Answer: (b).They can be operated accidentally and may be awkward to use, especially with laptops. Explanation:While foot-operated controls like the footmouse are not intrinsically a bad idea (and are, in fact, commonly used in musical instruments and industrial controls), two main issues limit their widespread use in computer interfaces. One is the practicality of having such controls in the work environment. Pedals under a desk could be accidentally operated and using such devices with laptops would be inconvenient.
