HotStrokes - Word-Gesture Shortcuts on a Trackpad

Explore an innovative interaction technique called HotStrokes in this 21-minute conference talk from the ACM CHI Conference on Human Factors in Computing Systems. Learn how HotStrokes improves upon traditional hotkeys by allowing users to gesture type command names on a laptop trackpad while holding a modifier key. Discover the adaptation of the SHARK2 algorithm used for gesture recognition, including a new spatial model and refined dynamic suggestions. Examine the results of a controlled experiment demonstrating HotStrokes' efficiency in reducing command activation time by 43% compared to linear menus, its ease of learning, and high adoption rate. Gain insights into how combining linear menus, hotkeys, and HotStrokes can lead to 24% faster overall command activation, potentially revolutionizing user interface interactions.
