To receive user-experience oriented measurements on rendered image content, you can set checkpoints on images and expect an accuracy of ±½ second in the UX timer, based on the real result. For example, if the real image shows 10 seconds from the trigger of the checkpoint, the UX timer will be between 9.5 seconds and 10.5 seconds. The UX timer is based on rendered text and images from the device UI, ensuring the desired rendered content is indeed visible and recognizable. This is different from other methods, including network traffic analysis or native object analysis, which may give false insight where the desired content is not, in fact, rendered on the screen.
To achieve a UX timer with high accuracy, define the following parameter settings:
