Abstract
A system to measure latency in displaying a key tap event corresponding to a touchscreen keyboard is disclosed. The system includes a text input module, configured to capture pre-defined text for latency measurement. The system includes a keyboard selection module, configured to select a virtual keyboard for the latency measurement with respect to the pre-defined text. The system includes a keyboard configuration module, configured to capture positional details of each text character of the pre-defined text with respect to registered virtual keyboard. The execution module, configured to execute the key tap event for each of the text character of the pre-defined text for latency measurement, to measure time gap of each text character of the pre-defined text between the key tap event and corresponding text display event and also configured to calculate average latency measurement of the pre-defined text from a measured time gap for each of the character.
