GyroWand: An Approach to IMU-Based Raycasting for Augmented Reality

Area of Science:

• Computer Science
• Human-Computer Interaction
• Virtual Reality

Background:

• Optical see-through head-mounted displays (HMDs) are key to augmented reality (AR), overlaying virtual objects onto the real world.
• Low-cost tracking technologies are crucial for interpreting user motion and enabling interaction with virtual content in AR.
• Current tracking methods present limitations in interaction possibilities despite pervasive tracking advantages.

Purpose of the Study:

• To introduce GyroWand, a new raycasting technique designed to overcome interaction limitations in AR HMDs.
• To enhance user interaction capabilities within augmented reality systems.
• To leverage inertial measurement unit (IMU) data for improved AR navigation and control.

Main Methods:

• Development of GyroWand, a raycasting technique specifically for AR HMDs.
• Utilizing rotational data from an inertial measurement unit (IMU) integrated into a handheld controller.
• Implementing the technique to interpret user motion for virtual object interaction.

Main Results:

• GyroWand enables effective raycasting for AR HMDs using IMU rotational data.
• The technique addresses limitations in interaction possibilities associated with pervasive tracking.
