Designing Page Scrolling Gesture using Gesture-Specific Heuristics in Leap Motion Validating The Gesture-Specific Heuristics By Creating Optimal Gestures

Optimal gesture creation is marred with many uncertainties, challenges and is still at its infancy stage. For hand-tracking devices such as that invented by Leap Motion, there is a lack of well-established gestures on controlling the operating system to perform basic operations. The gesture-specific heuristics (GSH) are a set of guidelines that could be used to evaluate and design gestures that would suit the limitation of the device and operating environment. This study narrows the gesture design to a single activity - simulating mouse wheel scrolling. However, the designing process comes with major obstacles. GSH needs to be supplemented with existing usability heuristics that tackles non-gestural design issues. The end results of combining GSH with existing usability heuristics produces a gesture that is more optimal than the existing available solutions. Moving forward, additional heuristics, taking into account user expectancy of the gesture nature needs to be considered.
