OptoFidelity TOUCH

OptoFidelity TOUCH comes with a purpose-built GUI, test sequencer and test reporting. In addition, a scripting API is available for custom tests. The camera-based positioning feature provides a convenient and accurate way to define the location of the device under test (DUT). The smart DUT detection enables test scripting by using DUT screen coordinates and the testing of multiple DUTs in the robot work area, as well as volume testing in less time and with better accuracy. The motion control supports synchronized motions enabling all types of touch gestures.

The default TOUCH test system is delivered with factory calibration for the camera system and for the motion control accuracy. The motion control accuracy of the delivered TOUCH test system is verified with an external measurement system supporting +/-25 μm accuracy.

It takes little time to deploy the TOUCH test system. The system delivery includes on-site system setup and training which enable users to start testing right away. Support services are available to provide any needed guidance and help for further usage of the system.

Test features

OptoFidelity TOUCH is used for measuring the performance of the following human-like gestures on any touch device:

• One-finger gestures: Tap, press, swipe, drag, double tap, multi tap, circle and path
• Two-finger gestures: Tap, swipe, pinch (zoom in/zoom out) and rotate
• Multi-finger gestures: Tap and swipe

Test metrics:

• Touch Accuracy, i.e. the accuracy of the tap gesture position reported by the touch panel compared to the programmed position of the tap
• Touch Jitter, i.e. variation in detected touch screen coordinates while finger is motionless or drawing a straight line
• Touch Linearity, i.e. how accurate the touch panel coordinates are compared to the actual, programmed position of the linear swipe gesture
• Touch Reporting rate, i.e. the frequency of reporting in the touch panel
• Touch Resolution, i.e. the smallest increment of position change that the touch panel is reporting
• Touch Latency, i.e. the level of delay between the tap gesture and receiving the related touch event (touch panel level test)
• Touch Sensitivity, i.e. the level of signal received from the touch sensor (touch panel level test)
