LightGuide: Projected Visualizations for Hand Movement Guidance

When performing complex gestures that require a specific form or technique, such as an exercise or playing an instrument, we use resources such as visual diagrams or videos to communicate concepts like posture, movement and speed of motion. Without incremental and real-time feedback such as those we receive from an instructor, interpreting and following a set of instructions can be a challenge. LightGuide is a new approach to gesture guidance, where digital hints are projected directly on a user’s body. The techniques are focused on guiding a user’s hand freely, providing feedback and feed forward queues to help guide users through a range of movements. The queues provide collocated instructions for the movement, along with the body part that is moving on the desired path.
