A total of 30 university students were divided into three groups depending on the correction method for their wrist angle: control (no feedback), experimental (vibrotactile feedback) and instructed (trainer feedback). The experimental protocol consisted of four sessions, with data collection occurring from the second to the fourth session. The primary metric was the proportion of time the wrist maintained the correct flexion-extension angle, which was individually tailored for each participant with the help of a trainer. The results showed significant interaction effects between feedback type and session number. The vibrotactile system demonstrated higher average percentages of wrist alignment compared to the control (23% more) and trainer (15% more) groups, possibly indicating learning effects. These findings are explained throughout the document and support the use of vibrotactile feedback as an effective tool to monitor and improve wrist posture, highlighting its potential in motor skills learning and haptics research.TextoengopenAccesshttp://creativecommons.org/licenses/by-nc/4.0INGENIERÍA Y TECNOLOGÍA::CIENCIAS TECNOLÓGICAS::TECNOLOGÍA MÉDICA::OTRASTechnologyTesis de maestríaHaptics, vibrotactile feedbackMotor skill learningVibrations, wrist angleReal-time feedback1317997
