Touch Accuracy: The Key to Success for IVI Systems

In the modern automotive industry, the In-Vehicle Infotainment (IVI) system has become an indispensable part of vehicles. IVI systems improve the convenience and comfort of driving and integrate functions such as navigation, music playback, communications, and information displays. Moreover, these functions all rely on the interactive touch screen. If there is poor touch accuracy on IVI systems, drivers are likely to face operational errors and experience confusion during usage.

For example, if a driver is trying to adjust the volume and the poor touch accuracy results in switching on the music or if a driver is trying to change songs but changes the navigation destination instead, it can seriously affect the driving experience. In more serious cases, it could even put the driver’s safety at risk. Another example would be if a driver attempts to turn on the seat heating or air conditioning, but the poor touch accuracy does not allow the driver to do so, it could cause inconvenience to the driver, especially in bad weather conditions. These potential issues shine a light on the necessity of strict verification testing for IVI systems.

A Fatal Mistake: Measuring Touch Accuracy for IVI Systems

Entrusting a Third-party Testing Laboratory is Better for Complex Touch Accuracy Testing

When dealing with touch accuracy testing, manufacturers often encounter difficulties when simulating user behavior and improving the accuracy during repeated actions. This not only relies on high-precision testing equipment, such as the UR5 robotic arm that has an accuracy of ±0.01mm, but it is also extremely complex to calculate data and execute the test. Most manufacturers need expensive testing equipment and also specific knowledge with practical experience in testing. Therefore, manufacturers seeking assistance from professional third-party testing laboratories like Allion can efficiently allocate limited resources and time into the development of new products and features. This enhances innovation capabilities, sustaining a competitive advantage in the market.


A Closer Look of Touch Accuracy Testing

Let’s look at one of our clients, a touch panel manufacturer, as an example. They contacted Allion to verify and test the touch accuracy of their product and required the error standard to be within 1mm. By using our UR series robotic arm with a customized clamping fixture, we successfully tested 81 points. It was found that two of the points had exceeded the error standard of 1mm. Our client then made adjustments and sent the product back to us for verification once again. In the end, all of the touch points had error standards of under 1mm, meeting their requirements for shipping.


This result not only demonstrates Allion’s industry-leading technology but also reflects the urgent demand in the market for high-precision touch accuracy. Modern consumer requirements for automotive technology are constantly increasing and touch precision has become a very important factor in terms of market competition. Allion’s professional consulting team has an in-depth understanding of current market trends and can provide clients with comprehensive solutions such as technical analysis or actual testing, helping clients with their market requirements and enhancing competitiveness in their products.
