Evaluation of AI-Mouse Use in Patients With Hand and Wrist Conditions
10 juli 2026 uppdaterad av: Nazarbayev University
People with hand and wrist conditions, such as carpal tunnel syndrome or hand injuries, often experience pain and discomfort when using a computer mouse.
This study will evaluate a new artificial intelligence (AI)-assisted computer input system ("AI-mouse") designed to reduce the amount of hand movement needed during computer tasks.
Participants will complete short computer-based tasks using both a conventional mouse and the AI-assisted system while researchers measure task performance, muscle activity using surface electromyography (EMG), and participants' ratings of pain, physical strain, and usability.
The study aims to determine whether the AI-assisted system can reduce physical effort and muscle load while maintaining effective computer interaction.
Findings may help improve accessible computer technologies and support the development of ergonomic tools for people with hand and wrist impairments.

Deltagargrupp / Arm |
Intervention / Behandling |
|---|---|
|
Aktiv komparator: Conventional Mouse
Participants perform standardized computer pointing tasks using a conventional computer mouse.
Performance (task completion time, error rate, throughput), surface electromyography (EMG) of upper-limb muscles, and participant-reported outcomes (pain, physical strain, and usability) are assessed during task completion.
|
A standard computer mouse used for conventional point-and-click interaction.
Participants complete the same standardized computer tasks as in the experimental condition, allowing direct comparison of task performance, upper-limb muscle activity measured by surface electromyography (EMG), and participant-reported pain, physical strain, and usability.
|
|
Experimentell: AI-Mouse (Preview-Accept-Discard [PAD] System)
Participants perform the same standardized computer tasks using the AI-Mouse, a predictive human-computer interaction system based on the Preview-Accept-Discard (PAD) paradigm.
The system generates AI-assisted action suggestions that can be accepted or discarded using minimal keyboard input, reducing cursor movement.
Performance, surface electromyography (EMG), and participant-reported outcomes (pain, physical strain, and usability) are assessed during task completion.
|
A non-invasive computer input system that uses artificial intelligence to predict the user's intended on-screen action.
Instead of relying primarily on continuous cursor movement and mouse clicking, the system presents predicted actions that participants can preview, accept, or discard using minimal keyboard input.
The intervention is designed to reduce repetitive hand movements during computer interaction while preserving user control.
Participants complete standardized computer tasks using the system during a single study session lasting less than four minutes.
