Touch Panel, UI & Stylus Testing

Touchscreens are used in diverse fields of electronics

The touchscreen is a vital component of consumer electronics. Touchscreens are used in smartphones as well as other types of smart devices, such as smartwatches, tablets, white goods and in automotive infotainment. Touchscreens are commonly used also in medical, industrial and commercial applications as well as in info displays.

Touch-enabled displays come in many sizes and shapes; from tiny smartwatches to large monitors and info displays with rectangular, rounded, flat, curved or even foldable physical shapes. A touch UI is usually controlled with various finger, hand or stylus gestures.

Human-simulating approach in smart device testing

Despite their diversity, touchscreens have one thing in common: the quality of a touchscreen is based on the end users' perceptions. Motivated by this fact, OptoFidelity has adopted a so-called human-simulating approach in designing automated test systems for demanding customers. In addition to having human-like test systems, we also think it's important to understand the timing – when something should be tested. To create the best possible end user experience, it is important to perform appropriate testing on every stage of the product's life cycle.

See the table below for a better understanding of what kind of touch-related testing we recommend for each stage in the product's lifecycle.
