Automotive touchscreen force testing solutions

Getting haptic feedback right on a vehicle touchscreen depends on accurately capturing the force behind every tap, which is exactly what this vehicle interface force testing solution is built to do. SMTM Micro S-Type Load Cells are mounted behind the bezel attachment points of the touchscreen, with load cell load buttons passing through each sensor to secure both the load cell and the screen assembly. When a user taps the screen, the SMTM measures the contact force, and the analogue output is captured through the compact, high-speed 9330 Battery Powered Data Logging Indicator, either straight to a laptop or via SD card. With this setup, engineers can confirm the automotive system correctly detects touch input and delivers the right haptic feedback response every time.
