Background: A mouse is an important communication interface between a human and a computer, but it is still difficult to use for the elderly or disabled.
Objective: To develop a low-cost computer mouse auxiliary tool.
Methods: The principal structure of the low-cost mouse auxiliary tool is the IR (infrared ray) array module and the Wii icon sensor module, which combine with reflective tape and the SQL Server database.
Results: This has several benefits including cheap hardware cost, fluent control, prompt response, adaptive adjustment and portability. Also, it carries the game module with the function of training and evaluation; to the trainee, it is really helpful to upgrade the sensitivity of consciousness/sense and the centralization of attention. The intervention phase/maintenance phase, with regard to clicking accuracy and use of time, p value (p< 0.05) reach the level of significance.
Conclusions: The development of the low cost adaptive computer mouse auxiliary tool was completed during the study and was also verified as having the characteristics of low cost, easy operation and the adaptability. To patients with physical disabilities, if they have independent control action parts of their limbs, the mouse auxiliary tool is suitable for them to use, i.e. the user only needs to paste the reflective tape by the independent control action parts of the body to operate the mouse auxiliary tool.
