Query: Holoscopic 3D Micro-Gesture Database for Wearable Device Interaction   With the rapid development of augmented reality (AR) and virtual reality (VR)
technology, human-computer interaction (HCI) has been greatly improved for
gaming interaction of AR and VR control. The finger micro-gesture is one of the
important interactive methods for HCI applications such as in the Google Soli
and Microsoft Kinect projects. However, the progress in this research is slow
due to the lack of high quality public available database. In this paper,
holoscopic 3D camera is used to capture high quality micro-gesture images and a
new unique holoscopic 3D micro-gesture (HoMG) database is produced. The
principle of the holoscopic 3D camera is based on the fly viewing system to see
the objects. HoMG database recorded the image sequence of 3 conventional
gestures from 40 participants under different settings and conditions. For the
purpose of micro-gesture recognition, HoMG has a video subset with 960 videos
and a still image subset with 30635 images. Initial micro-gesture recognition
on both subsets has been conducted using traditional 2D image and video
features and popular classifiers and some encouraging performance has been
achieved. The database will be available for the research communities and speed
up the research in this area.
