We present EyeWrist, which uses palms as the gesture interface for smart wearable displays such as Google Glass. With abundant tactile cues and proprioception on palms, EyeWrist can also be leveraged for device-less and eyes-free remote for smart TVs. EyeWrist embeds a micro-camera and an IR laser line generator on the wristband and use computer vision algorithms to calculate the finger’s position on the palm. Without requiring the line of sight of users’ fingertips on palms, the camera height could be lower, making the whole device more portable. We also implemented a gesture recognizer to distinguish different symbols, letters or touchscreen gestures(e.g. swipe, pinch) on palms. The recognition result would be sent to smart devices via Wi-Fi for gesture-based interaction.
