| Popis: | In this study, we measured wrist torque perception in conditions that mimic activities of daily living. We tested five participants with a two-alternative forced choice paradigm torque comparison test while the user was both seated and walking, with both a stationary and a moving wrist. Reference torque, walking, and moving wrist all significantly affected the results. Both walking and moving wrist conditions resulted in higher Weber fractions (worse perception), and the conditions with the smallest wrist flexion reference torque while walking and moving the wrist had significantly higher Weber fractions than a number of others. This information provides insight regarding the design of wearable kinesthetic haptic devices worn at the wrist. |
