A notebook computer mouse named Long Tail, inspired by the power cable cords of electric vacuum cleaners that are automatically rolled in after use. Reflecting the sales trend where more and more consumers prefer laptops to desktops, and the increasing demand of users for mobility, we solved these simple needs and wants by maximizing the mobility, without hassle, having the mouses power cable automatically rolled in. Also, we provided an easily maneuverable scroll located between the two buttons of the mouse by applying touch sensing function. At the same time, we gave more texture to the scroll to enhance the tactile experience
