A footmouse (also spelled foot mouse) is a type of computer mouse that gives the users the ability to move the cursor and click the mousebuttons with their feet. It is primarily used by users with disabilities or with high-back or neck problems. It is also promoted as a way to prevent such problems in the future and as a means to increase productivity by not having to move one's hand between the keyboard and mouse.
