We present PalmType, which uses palms as interactive keyboards for smart wearable displays, such as Google Glass. PalmType leverages users' innate ability to pinpoint specific areas of their palms and fingers without visual attention (i.e. proprioception), and provides visual feedback via the wearable displays. With wrist-worn sensors and wearable displays,(More)
In this paper, we explored eyes-free gesture interactions on palms, which enables users to interact with devices by drawing stroke gestures on palms without looking at palms. We conducted a 24-person user study to understand how users draw gestures on the palm with varying characteristics including regions, orientation and starting points. Based on the(More)
We present a novel gestural interface for an educational 3D construction game that helps children practice and learn spatial reasoning skills. Previous research shows that having well-developed spatial reasoning skills is crucial to the success in the STEM fields. Our game requires the player to create a number of 3D target objects by moving, rotating, and(More)
Certain commercial video games, such as Portal 2 and Tetris, have been empirically shown to train spatial reasoning skills, a subset of cognitive skills essential for success in STEM disciplines. However, no research to date has attempted to understand which specific features in these games tap into players' spatial ability or how individual player(More)
