Method: The system controls the movement and direction of the mouse cursor by capturing head movement images using a marker installed on the user's headset. In the clinical trial, this new mouse system was compared with an infrared-controlled mouse system on various tasks with nine subjects with SCI. Results: The results were favourable to the new mouse system. The differences between the new mouse system and the infrared-controlled mouse were reaching statistical significance in each of the test situations (p<0.05). Conclusions: The HMI-controlled computer mouse improves the input speed. People with disabilities need only wear the headset and move their heads to freely control the movement of the mouse cursor.[SDGs]SDG3[SDGs]SDG4[SDGs]SDG10adult; article; calculation; clinical article; clinical trial; computer interface; computer system; controlled clinical trial; controlled study; head movement; human; image processing; infrared radiation; male; microprocessor; physical disability; priority journal; spinal cord injury; statistical analysis; task performance; Communication Aids for Disabled; Computer Peripherals; Computer Systems; Equipment Design; Female; Head Movements; Humans; Male; Quadriplegia; Rehabilitation, Vocational; Sensitivity and Specificity; Spinal Cord Injuriesjournal article10.1080/0963828021000024960
