• Demonstrating Eyes-Free Object Retrieval via Fingertip Deflection Guidance Using the NURing

  Tomasz P. Trzpit, Gregory Reardon, Elizabeth Gerber, Pedro Lopes, Michael Peshkin, J. Edward Colgate (2026) — Extended Abstracts of the 2026 CHI Conference on Human Factors in Computing Systems (CHI EA ’26)

  This CHI 2026 Extended Abstract is an interactive-demo paper introducing a vision-enabled version of NURing, a tendon-driven wearable ring that guides reach by gently deflecting the wearer’s fingertip. The authors frame the work around a recurring re…

• Camera-Based Closed-Loop Fingertip Deflection Guidance: Pilot Demonstrations in Target Acquisition and Object Retrieval

  Tomasz P. Trzpit, Gregory Reardon, Elizabeth M. Gerber, Pedro Lopes, Michael A. Peshkin, J. Edward Colgate (2026) — Extended Abstracts of the 2026 CHI Conference on Human Factors in Computing Systems (CHI EA ’26)

  This CHI 2026 Extended Abstracts poster from the Northwestern/University of Chicago team behind the NURing project presents a camera-enabled evolution of their fingertip-deflection guidance wearable. The authors argue that most eyes-free guidance sys…
