Abstract
An input device allowing the user to quickly differentiate between the input states is provided. The input device includes a cap, a first light source, a second light source and a control module. The first light source radiates a first light of a first color and the second light source radiates a second light of a second color. The cap includes a first portion and a second portion. The first portion displays the light of the first light. The second portion displays the light of the second light. When the input device is in a first state, the control module controls the first light source to radiate the first light to illuminate the first portion. When the input device is in a second state, the control module controls the second light source to radiate the second light to illuminate the second portion.
