In-vehicle infotainment (IVI) UX is the design of how drivers and passengers interact with a vehicle's digital interfaces through touch, voice, steering-wheel controls, visuals, and sound. A good IVI system makes it easy to navigate, control media and climate, check vehicle information, and use connected features while keeping driver distraction low.
IVI UX brings together safety, software, and human behaviour at the same time, which makes it one of the harder areas of automotive product design. Each interaction needs to be quick to understand and responsive so it doesn't pull the driver's attention away from the road.
This guide covers what IVI UX is, why it matters, and how to design IVI systems that are safe, easy to use, and even enjoyable.
What is In-vehicle Infotainment (IVI) UX?
In-vehicle infotainment (IVI) UX is the user experience of a vehicle's digital infotainment system and the connected services it brings together. An IVI system brings navigation, media, phone integration and communication, connectivity, and many vehicle settings into one or more screens, plus voice and physical controls. IVI UX is the craft of making all of that easy, efficient, and safe to use while driving.
In many modern vehicles, the IVI works alongside the digital instrument cluster, steering-wheel controls, voice assistant, and sometimes a head-up display to create a connected cockpit experience.
The job of IVI UX is to decide what each of these shows, when it shows it, and how a person moves between them without getting lost or distracted.

In-vehicle Infotainment vs Telematics vs The Connected Car: The Differences
Infotainment, telematics and the connected car are related, but separate ideas, and design teams should not treat them as one thing. Infotainment is the digital interface people use to access media, navigation, communication, connected services and many vehicle functions.
Telematics is the technology that collects, transmits and receives vehicle data, such as location, diagnostics, driving behaviour and vehicle health. The connected car is the wider system that connects the vehicle to cloud services, mobile apps, infrastructure and, in some cases, other vehicles.
| Term |
What it means |
Example |
| Infotainment |
The vehicle's digital interface for media, navigation, communication, connected services and vehicle functions |
Choosing a playlist, entering a destination or adjusting climate settings |
| Telematics |
The technology that collects and exchanges vehicle data with cloud services |
GPS location, battery or fuel status, diagnostics, service alerts |
| Connected car |
A vehicle connected to cloud services, mobile apps and digital networks |
Over-the-air updates, remote unlock from a phone |
| Navigation |
The route-planning and guidance feature within the infotainment system |
Turn-by-turn directions on the central screen |
In simple terms, telematics provides the data, connectivity enables it to move, and the infotainment system presents it to the driver.

How is In-vehicle UX Different From Mobile and Web UX?
In-vehicle UX differs from mobile and web UX mainly because of safety, attention, and context. On a phone or computer, interacting with the screen is usually the primary task. In a vehicle, driving remains the primary task, and interacting with the interface is secondary.
The practical differences are large.
- Touch targets need to be bigger because a moving car makes fine taps hard.
- Menus need to be shallower so a task can finish in a glance or two.
- Feedback often has to work through sound or touch, because long visual interactions increase driver distraction.
- Colours and contrast have to survive bright sun and night driving.
- The system has to change with the situation, for example by limiting or adapting certain tasks while the vehicle is moving.
Unlike most mobile and web interfaces, IVI systems rely on multiple interaction methods, including touch, voice, steering-wheel controls, and haptic feedback, to help people complete tasks while keeping visual attention on the road.
Why Does In-Vehicle Infotainment UX Matter for Safety and Business?
Poor in-car design is a road safety problem as well as a product experience one. Every extra second a driver spends hunting for a function is a second their attention is split between the road and the screen. Good IVI UX cuts down on unnecessary interaction, lets drivers finish tasks faster, and makes the vehicle feel more trustworthy. It also affects how customers judge the product's quality long after they buy it.
The Impact of IVI UX on Driver Safety
Driver distraction is one of the biggest problems in IVI design. Research has revealed that taking your eyes off the road for just two seconds doubles the risk of a crash.
The same research found that entering a navigation destination took up to 40 seconds in the test scenarios. Navigation entry was the most demanding task tested, which shows how a poorly designed interface can keep drivers visually and mentally occupied far longer than they should be.
Accessibility makes the problem harder. In a follow-up study, drivers aged 55 to 75 took between 4.7 and 8.6 seconds longer than younger drivers to finish the same infotainment tasks. That is why inclusive design is a safety concern and not only a usability one. Interfaces that are simpler for older drivers tend to be better for everyone.
For design teams, this means reducing interaction time. Simpler navigation flows, shallower menus, better voice interaction, and showing the right information at the right moment all cut the time drivers spend on the system instead of the road.
What’s The Business Case for Good IVI UX?
Good IVI UX matters commercially too. For many customers, the infotainment system is one of the most-used parts of the car and one of the first things they judge once they own it. A confusing interface leads to frustration, support requests, and bad reviews. But a clear one improves how people rate the product and the brand, and it keeps them satisfied over time.
As cars become more software-defined, the interface also becomes the way in to connected services, over-the-air updates, premium features, and subscriptions. The easier those are to find and use, the more customers get out of the vehicle over the years they own it. Good IVI UX supports safer driving, and it also lifts feature adoption, customer loyalty, and a brand's standing in a market that increasingly competes on software.

What are the Components of an IVI System?
An IVI system has three main layers: the hardware people interact with, the software and operating system that runs it, and the connectivity that links the car to the wider world. Designing good IVI UX means understanding all three, because each one sets limits on what the experience can do.
The Hardware Layer
The hardware layer is everything physical the person sees and touches. It includes the central touchscreen, the digital instrument cluster behind the wheel, any head-up display that projects information onto the windscreen, physical buttons and dials, steering-wheel controls, and the microphones and speakers used for voice and audio. At the heart of the IVI system sits a system-on-chip (SoC), which largely determines how responsive and visually rich the experience feels.
Hardware choices shape the design brief before a single screen is drawn. Screen size and position affect how far the driver's eyes travel. The presence or absence of physical dials changes how climate and volume are handled. A slower processor forces simpler animations and fewer live elements. Designers who ignore these limits produce work that cannot ship.
The Software Layer
The software layer is the operating system and applications that run the experience. Common automotive operating systems include QNX, Automotive Grade Linux (AGL), and Android Automotive OS. On top of the operating system sit the apps, the interface framework, and the design system that keeps everything consistent.
The industry is shifting from hardware to software as the main source of value and differentiation. That is why the choice of operating system now carries so much weight. It affects how apps are built, how updates are delivered, and how much control the carmaker keeps over the experience.
Connectivity and the Software-defined Vehicle
Connectivity is the layer that links the car to the cloud, to phones and to services, and it is turning cars into software-defined vehicles. A software-defined vehicle is one where features are delivered and improved through software, often after the car has been sold. Over-the-air updates, live traffic, streaming media, and remote functions all depend on this layer.
Connectivity also allows the IVI to receive real-time vehicle data, such as battery status, range, diagnostics, and ADAS information, enabling more context-aware experiences.
This changes IVI UX in a lasting way. A system is no longer finished at launch. It can gain features, fix problems, and change its interface over the life of the car. Designers now have to plan for a product that keeps evolving, which means clear versioning, careful change management, and a design system that can grow.
The same design principles extend beyond the dashboard. Our work on Royal Enfield's connected ownership experience used telematics to surface real-time vehicle information, geofencing, and health insights through a companion app. Although outside the in-vehicle interface itself, it reflects the same shift towards software-defined, connected vehicle experiences.
Core Principles of Effective IVI UX Design
Effective IVI UX helps drivers finish tasks with as little distraction as possible. Every design decision should lower visual demand, mental effort, and interaction time while keeping the information drivers need easy to find. The principles below help designers build in-vehicle experiences that are safer and easier to use in real driving conditions.
1. Minimise Cognitive Load and Interaction Time
Reduce how much thinking and interaction a task takes. Common actions should need the fewest possible steps, and frequently used controls should be easy to reach and read. So interactions have to stay short. No everyday task should call for a long, uninterrupted glance at the screen.
2. Design for Glanceability
Drivers should be able to read the screen in a glance and get their eyes back on the road. Large type, strong colour contrast, clear icons, and a well-defined visual hierarchy all help. Critical information, like the next navigation instruction, speed, or a safety alert, should always stand out while secondary information stays quiet. Every unnecessary element on screen adds to the driver's load and slows recognition.
3. Design for Multimodal Interaction
A good IVI experience lets people move naturally between touch, voice, steering-wheel controls, and haptic feedback depending on the task and the driving conditions. Giving drivers more than one way to do the same thing lowers distraction and widens access without making the interface more complicated.

4. Use Context-aware and Adaptive Interfaces
A well-designed IVI experience responds to what's happening on the road instead of showing the same layout all the time. Navigation prompts should grow more prominent as a turn approaches, and less important functions should fade back. Some interactions may need to be simplified, limited, or switched off while the car is moving, and the interface should adjust to conditions like night driving or a low battery. Context-aware design does the deciding for the driver by surfacing the right information at the right moment.
5. Use Progressive Disclosure
Not every option needs to be on screen at once. Progressive disclosure keeps the interface focused. It shows the most important information first and reveals advanced controls only when they're needed. That cuts visual clutter, makes navigation easier, and keeps drivers from feeling overwhelmed during everyday tasks.
6. Provide Clear Feedback and Easy Error Recovery
Drivers should always know whether the system caught their input. A brief visual cue, a subtle sound, or a light haptic buzz can confirm an action without holding attention. Consistent patterns across screens help people learn the system, and simple recovery paths, like an obvious Back button, undo options, or a clear confirmation message, make mistakes easy to fix.
7. Design for Personalisation Without Adding Complexity
Cars are often shared, so the in-car experience should adapt to different drivers without creating extra work. User profiles can remember seat position, mirror settings, climate preferences, favourite destinations, media settings, and frequently used apps. Done well, this saves people from repeating setup and gets them on the road faster.

8. Make Accessibility and Inclusive Design a Requirement
Accessibility is a core part of safe IVI design rather than an add-on. An inclusive interface should work for people of different ages, abilities, languages, and comfort with technology. Readable type, generous touch targets, clear voice interaction, high colour contrast, and support for assistive technologies all make the system safer to use. Building accessibility in from the start helps everyone.
9. Build on a Scalable Design System
Applying these principles across many screens, vehicle models, and software updates takes more than careful design; it takes a solid design system. Shared components, interaction patterns, and accessibility standards let teams ship consistent experiences with less duplicated work. As cars become more software-defined and gain features through over-the-air updates, a scalable design system lets the in-vehicle experience keep changing without losing usability or consistency.

Which Standards and Guidelines Shape IVI UX Design in India?
India does not have dedicated IVI UX regulations equivalent to the NHTSA Driver Distraction Guidelines in the United States. Instead, Indian automotive teams typically design against internationally recognised human-machine interface (HMI) principles while complying with Indian automotive safety requirements. For vehicles sold globally, manufacturers also align with the standards and assessment programmes of their target markets.
| Framework |
Why it matters for IVI UX |
| ISO 15005 |
Defines ergonomic principles for designing transport information and control systems. |
| ISO 15007 |
Provides methods for measuring driver visual behaviour and glance patterns. |
| NHTSA Driver Distraction Guidelines (US) |
Recommend limiting visual distraction and prolonged interactions while driving. Widely used as a design reference. |
| Euro NCAP |
Encourages dedicated physical controls for safety-critical functions as part of its vehicle safety assessments. |
| UN R155 & UN R156 |
Set requirements for connected vehicle cybersecurity and secure over-the-air software updates. |
Whether designing for the Indian market or global exports, the underlying UX principles remain consistent. That is, minimise driver distraction, reduce cognitive load, support multimodal interaction, and keep safety-critical controls easy to access. With Indian OEMs continuing to build software-defined and connected vehicles, these global standards increasingly shape how IVI systems are designed, tested, and improved over time.
How Do You Design an IVI System? A Step-by-Step UX Process
Designing an IVI system follows a research-led UX process, moving from understanding drivers to testing the interface in realistic conditions. The steps below give a practical order of work.
Step 1: Contextual User and Driver Research
Start by learning how real people use the car, not how you imagine they do. IVI UX is also highly collaborative. Early research should involve designers, product managers, HMI engineers, software teams, and other stakeholders so user needs, technical constraints, and business goals are understood from the beginning rather than discovered late in development.
Useful methods include in-car observation, ride-alongs, interviews, driver personas, diary studies, and jobs-to-be-done analysis. Because the driving context is so specific, research done in a meeting room rarely tells the whole story. Watching people drive reveals the small frustrations that surveys miss.
This is the stage where good user research and usability testing pay off most. While designing the Royal Enfield ownership experience, we used stakeholder and rider insights to build an information architecture around real behaviour and mental models, and drew on ethnographic research into rider culture to shape the community features. Understanding how riders actually read their vehicle data came first; the dashboards came second.
Step 2: Information Architecture and Task Flows
Organise the system so common tasks are short and findable. Map the main jobs a driver needs to do, then design the shortest safe path to each one. Deep, nested menus are the usual cause of long glances, so the aim is to flatten the structure. A clear information architecture helps reduce the number and duration of glances needed to complete common tasks.
Step 3: Interaction and Modality Design
Decide how each task should be done: by touch, by voice, by a physical control, or from the steering wheel. Different tasks suit different inputs. Adjusting volume suits a dial or wheel button. Entering a destination is often safer using voice input than touch. Choosing between screens suits touch. Matching the task to the right input, and using dedicated physical controls for safety-critical functions, is central to safe design.
This stage also defines how information is presented. Labels, notifications, warnings, confirmation messages, and other interface content should be brief, easy to understand, and prioritised according to the driving context. Clear microcopy reduces hesitation and helps drivers make quicker decisions.
Step 4: Visual Design, Motion and the Design System
Design the visual language that brings the interface to life. Typography, colour, icons, spacing, motion, and animation should all support quick recognition rather than decoration. Every visual element should help drivers understand information at a glance across different lighting conditions, from bright sunlight to night driving.
These decisions are then captured in a design system made up of reusable components, interaction patterns, and accessibility standards. A robust design system keeps the experience consistent across screens, vehicle models, and future software updates while allowing teams to design and build more efficiently.
Step 5: Prototyping and Simulation
Turn the design into something people can interact with before development begins. Prototypes can range from simple clickable wireframes to high-fidelity experiences evaluated in driving simulators or controlled testing environments. Early testing helps teams identify usability issues before implementation, making changes significantly faster and less expensive than after development.
Unlike most digital products, IVI interfaces should be evaluated in realistic driving conditions wherever possible. Simulated driving, closed-course testing, and other contextual evaluations reveal usability problems that rarely appear in office-based reviews.
Step 6: Usability Testing and Iteration
Test the experience with representative drivers, measure how well common tasks perform, and refine the design continuously. Useful measures include task completion time, task success rate, glance behaviour, error rates, and perceived cognitive workload. These metrics show whether drivers can complete tasks efficiently without unnecessary distraction.
Testing is not a one-off activity at the end of the project. Modern IVI systems continue evolving through software updates, so research and measurement should continue after launch. If an existing system is difficult to use, a structured UX audit helps identify usability issues before redesign begins.
How Do You Design the Key IVI Interaction Modalities?
An IVI system rarely relies on a single interaction method. Instead, designers must decide which input method works best for each task, balancing safety, speed, and ease of use across touch, voice, physical controls, and multiple displays.
Touchscreen UX for Automotive
Automotive touchscreens should prioritise high-frequency tasks, maintain consistent control placement, and minimise gestures that require precision. Unlike smartphones, in-vehicle touch interactions must remain usable despite vibration, changing lighting conditions, and divided driver attention.
Voice UX and AI Assistants
Voice interaction can reduce the need for visual and manual input, making it one of the safest ways to complete many in-vehicle tasks.
Good voice UX understands natural, conversational commands, gives short and clear spoken replies, and does not force the driver to look at the screen to confirm. Modern voice assistants increasingly use AI to understand natural language, maintain conversational context, and complete more complex tasks.
The design challenge is trust. The system must be accurate and predictable, or people stop using it.
Physical Controls, Haptics and Steering-wheel Integration
Physical controls remain the safest option for frequent, safety-critical actions. Dials, buttons and steering-wheel controls can be found by feel, without looking. Haptic feedback, a small vibration or click, can confirm an action through touch alone. A well-judged mix of physical and digital controls usually beats an all-screen cabin for safety.
Navigation UX in Vehicles
Navigation is one of the most-used and most safety-sensitive parts of an IVI system, so it deserves special care. Guidance should be clear and timed well, with the next instruction easy to see or hear at the moment it is needed. When drivers need to enter a destination while parked or before a journey, voice input and saved locations can reduce interaction time compared with manual entry.
Multi-screen, Head-up Displays and AR Interfaces
Modern cabins spread information across several displays, so the design has to decide what belongs where. The instrument cluster suits driving-critical data such as speed and the next turn. The central screen suits media, settings, and detailed navigation. A head-up display can place key information in the driver's line of sight, reducing how far the eyes travel.
Augmented-reality displays go further by overlaying guidance onto the real view of the road. The principle across all of them is the same. Put the most urgent information within the driver's natural line of sight, and keep each screen focused on its job. Designing across multiple displays requires a clear understanding of information hierarchy so every screen complements the others instead of competing for the driver's attention.
How Does IVI UX Change for Electric Vehicles?
Electric vehicles bring information needs that older infotainment systems were never built to handle. On top of navigation and media, drivers need to see battery status, estimated range, nearby charging, energy use, and charging progress in real time. Showing this clearly is what keeps range anxiety down and helps drivers decide with confidence.
A good EV IVI experience shows how much range is left and also why that number moves. Speed, terrain, climate control, and traffic all draw on the battery. The interface should explain these shifts in a plain, predictable way, and it should tie route planning together with charging stops, live charger availability, and estimated charging times.
The experience doesn't end inside the car. EV drivers move between the infotainment system, charging networks, and companion apps across a trip, so those touchpoints need to work together. Our work with Statiq fits this wider EV picture, making charger discovery, availability, and charging workflows simpler so there's less friction before, during, and after a charge. These connected experiences sit outside the vehicle, but they complement the IVI by helping drivers make faster, surer charging decisions.

Designing the Next Generation of In-Vehicle Infotainment Starts Here
A great IVI system comes from understanding how people actually drive, designing for safety and context, picking the right interaction for each task, and keeping the experience improving as vehicles get more connected and software-defined. Get those right, and IVI turns into something drivers rely on every time they get behind the wheel.
At Onething Design, we work with automotive and mobility brands to design connected experiences that make complex journeys simpler and technology easier to use. That includes rethinking Royal Enfield's connected ownership experience, building digital experiences that scale for TVS Motor, and designing EV charging for Statiq. The work is grounded in research and measurable outcomes.
