In-Car Touchscreen Sensitivity Consulting
Thanks to the widespread use of smartphones and tablets, users are accustomed to interacting with their electronic devices via touchscreens. Touchscreen technology is also gaining popularity in the automotive industry. However, if a touchscreen is over- or under-sensitive, it will not only deliver a bad user experience but also pose a real risk to driving safety. Allion now provides In-Car Touchscreen Sensitivity Consulting to tackle touchscreen issues, such as touchscreen performance, touch latency, and noise interference.Inquiry
Common Complaints about Touchscreens and Touchpads
- The touchscreen is not sensitive enough to give real-time response.
- The touchscreen does not respond to users’ touches or it takes too long to respond.
- Users cannot switch between open windows on the touchscreen.
- The touchscreen cannot be turned on and off for no apparent reason.
If an in-car touchscreen fails to respond instantly and correctly, it will seriously impact backup camera view, automotive navigation system, and other safety enhancement features.
Allion Consulting Team Helps You Find the Optimal Solution to In-Car Touchscreen Issues
Here we divide in-car touchscreen testing into 3 categories:
Touch Gesture Test
Touchscreens and touchpads should be able to respond to different gestures. Allion has developed a full range of validations for different touch gestures used in diverse driving scenarios. We use databases to analyze whether touchscreens or touchpads successfully detect the gestures and execute the specified command.
Basic gestures for most touch commands:
- Tap or Press
- Drag, swipe, or scroll
- Directional gestures
- Pinch and spread
Touch Latency Test
Touch latency is one of the decisive factors in the success of any touch device. When users tap or touch a touchscreen, they expect the touchscreen responds to their touches instantly. Allion has developed the most stringent touch latency test methods. We use a robotic arm to tap and swipe the icons on the touchscreen, and measure the touch response time required for different touch gestures. We will also collect and analyze the data to see whether the touch latency of a head unit display meets Allion’s regulatory requirements.
Advantages of Allion’s Automation System
|Advantages||High Efficiency, High Accuracy||24/7 Real-time Testing, Accelerate the Test Schedule||Beyond Human Capabilities||Big Data Collection and Analysis|
|Applications||The accuracy of manual testing can reach somewhat 83%-90% but it is easily affected by physical conditions, for example, fatigue.
However, automation testing can always remain 99% accuracy rate or even above.
|Working hours for human beings are 8 hours a day. However, robots can run 24 hours non-stop. An increase from 8 to 24 test hours a day suggests that the test schedule is accelerated (2-3 times faster).||Allion AI visual recognition system can solidly supervise the monitor without a break, check all the tiniest details, and capture fleeting actions displayed on the monitor. All of these operations are beyond human capabilities.||Allion AI system can analyze test results by collecting big data, including the test items with the highest error rates. The results can be references for future modifications and test planning.|
Electromagnetic interference or electrical noise is everywhere in our environment. Most electronic devices are susceptible to interferences, and automotive electronics are no exception. Noises in the environment may reduce the accuracy of touch. Thus, touchscreens and touchpads must provide sufficient anti-noise capability in both the hardware and the firmware to avoid the situation that the touch devices do not work.
In the anti-noise test, we simulate user scenario—apply the noise to touchscreen/touchpad by using robot arms. Through this user scenario, we can inspect the realness of device’s anti-noise capability.
A Test Report Tells More than a Thousand Words
Allion’s In-Car Touchscreen Sensitivity Consulting Is Sensitive to Your Needs
Consumers are intuitive decision makers. Even though automakers and head unit manufacturers might establish different levels or criteria of touchscreen sensitivity, consumers might find a test report issued by a third-party testing lab much more impartial and convincing.
As an independent test lab with 30 years of certification experience, Allion provides the most comprehensive engineering services for your touchscreen products. From training courses to technical support, our consulting services help you get a full picture of the industry specifications and setup your own test facilities.
Allion plays the role of overseeing product quality, and we strive to help product designers to improve their products and deliver a better experience to users.
