Research at: MIT Media Lab.
Role: Usability Studies (I came in after the development of the prototype, in the capacity of a UX researcher. I designed the experiment and analyzed the results)
Team of 4 with 2 engineers and a consultant.
Project Overview: We developed an augmented reality (AR)-controlled supernumerary robotic limb that uses eye gaze and voice commands to enable high-level control, aiming to reduce the cognitive load of traditional low-level interfaces. Through comparative usability studies with joystick-controlled and AR-controlled SRLs, we found that technical challenges limited our ability to demonstrate improvements in accuracy or efficiency with AR controls. We still believe there is significant potential for AR-based systems, and hope to refine and conduct future studies to better compare the systems.
Current control interfaces for supernumerary robotic limbs are often low-level, which results in a high cognitive load and discomfort for the user [1]. This can limit the effectiveness and usability of these devices.
