One-handed VR Controller

Publication link: TBA


Description:

The one-handed VR controller was designed for users who wish to interact with Virtual Reality using only one hand. The current work-in-progress one-handed VR controller has 11 buttons, seven with digital, four with analog output, and two joysticks. It combines the functionality of two conventional VR controllers into a single unit and can be motion-tracked with an HTC Vive Ultimate Tracker. 

Design Approach:

We designed the controller from an accessibility- and ergonomics-driven perspective, drawing on the literature and the current state of the art in VR controller design. We plan to evaluate the final one-handed VR controller with users who want to experience VR with only one hand after the design is complete.  

Implications for VR Experience:

The one-handed VR controller enables users to interact with Virtual Reality while only using one hand. This provides access and can reduce friction with the bimanual requirements of VR, potentially supporting presence and immersion.
