Project Houdini is a discovery project working with the Tap device, which is a wearable keyboard that can be used on multiple platforms with only one hand. The goal of the project is to explore the innovative use scenarios where Tap serves either as a standalone product or part of an integrated system including but not limited to integration with AR/VR devices. It aims to modify user’s input behavior, improve the input experience of certain user groups and ultimately bring impact to society.
