Touch Performance Testing
Testing and measuring touch performance is essential to guarantee functionality and quality for touch-enabled smart devices. Touch performance consists of the following measurable items:
- Tap accuracy, ie. the accuracy of the tap position in the touch panel compared to the programmed position of the tap
- Tap latency, ie. the level of delay in reproducing the intended functionality when tapping.
- Jitter, ie. variation in detected touch screen coordinates while finger is motionless or drawing a straight line
- Swipe accuracy, ie. how accurate the touch panel coordinates are compared to the actual, programmed position of the swipe
- Reporting rate, ie. the frequency of reporting in the touch panel
OptoFidelity Touch Performance System
OptoFidelity Touch Performance Test System is an automated test system for testing chipsets, touch panels, final products and systems. It includes a convenient and accurate, camera-based positioning feature to define the location of the device-under-test (DUT) which enables setting up of test with a new DUTs in less time, less errors and with more accuracy. Touch performance measurement is carried out for chipsets, touch panels and final products.

OptoFidelity Touch Panel Performance TesterThank you all for this lively interaction. We have collected FAQ to our website related to our widely spread iPhone measurement report. You can see our response to the most common speculations on http://www.optofidelity.com/archives/4016 .
Please stay tuned in to our YouTube Channel, we are definitely doing more test demo cases and videos for different devices and brands.
OptoFidelity Touch Panel Performance Tester is a turnkey solution for automatic measurement of key performance metrics from a touch panel. Test system consists of accurate robotic movements combined with touch sensor actuation for one, two and multiple fingers.
The key feature of the system is the software package that executes the testing process accurately and consistently. All touch sensor activation is done automatically including taps, swipes, zooms and other gestures. System changes activation methods automatically, so the complete test process can be executed without operator interaction.
OptoFidelity Touch Panel Performance Test System can be used to test both bare touch sensors and touch performance of touch enabled devices, such as smartphones and tablets. For convenience, test process is divided into separate sections for all the features that are tested. Different sections exist for single finger and multifinger testing as well as testing of coordinate accuracy, touch latency and gestures.
Test software is highly configurable by test parameters or with optional test application development tools. It is easy to perform a quick test with a small number of test points as well as an extremely thorough test process with high test point counts. The system features an interactive report, that shows the measured values as well as the requirement limits and provides pass/fail criteria for each test. Report is HTML based, and can also be accessed over the network. Test system includes OptoFidelity PIT for high accuracy measurements of touch latency directly from the touch controller chip interrupt.

In this video a calculator
application in a mobile phone is
tested using OptoFidelity One
Finger Delta Robot.
Robot has OCR, Icon detection,
state validation tools and
First the robot navigates in the
phone menu using OCR (Optical
Character Recognition) and icon
detection. After finding calculator
application robot opens it and
verifies that correct application was
opened using icon detection.
Actual application test is
implemented using OCR.
Once test is executed robot sets the
phone back to main menu.
