IntroductionIntroduction MouselessMouseless is an invisible computer mouse that is an invisible computer mouse that

provides the familiarity of interaction of a provides the familiarity of interaction of a physical mouse without actually needing a real physical mouse without actually needing a real hardware mouse. hardware mouse.

Despite these advances in computing hardware Despite these advances in computing hardware technologies, the two-button computer mouse technologies, the two-button computer mouse has remained the predominant means to has remained the predominant means to interact with a computer. The Mouseless interact with a computer. The Mouseless invention removes the requirement of having a invention removes the requirement of having a physical mouse altogether but still provides the physical mouse altogether but still provides the intuitive interaction of a physical mouse that intuitive interaction of a physical mouse that we are familiar with. we are familiar with.

Mouseless consists of an Infrared (IR) laser beam (with line Mouseless consists of an Infrared (IR) laser beam (with line cap) and an Infrared camera. Both IR laser and IR camera are cap) and an Infrared camera. Both IR laser and IR camera are embedded in the computer. The laser beam module is embedded in the computer. The laser beam module is modified with a line cap and placed such that it creates a plane modified with a line cap and placed such that it creates a plane of IR laser just above the surface the computer sits on. of IR laser just above the surface the computer sits on.

Laser beam lights up the hand which is in contact with the surface. The IR camera detects those bright IR blobs using computer vision. The change in the position and arrangements of these blobs are interpreted as mouse cursor movement and mouse clicks.

The change in the position and arrangements of these blobs are interpreted as mouse cursor movement and mouse clicks. As the user moves their hand the cursor on screen moves accordingly.

The user cups their hand, as if a physical The user cups their hand, as if a physical mouse was present underneath, and the laser mouse was present underneath, and the laser beam lights up the hand which is in contact beam lights up the hand which is in contact with the surface. The IR camera detects those with the surface. The IR camera detects those bright IR blobs using computer vision. The bright IR blobs using computer vision. The change in the position and arrangements of change in the position and arrangements of these blobs are interpreted as mouse cursor these blobs are interpreted as mouse cursor movement and mouse clicks. movement and mouse clicks.

As the user moves their hand the cursor on As the user moves their hand the cursor on screen moves accordingly. When the user taps screen moves accordingly. When the user taps their index finger, the size of the blob changes their index finger, the size of the blob changes and the camera recognizes the intended mouse and the camera recognizes the intended mouse click. click.

As we improve our computer vision As we improve our computer vision algorithms, an extensive library of gestures algorithms, an extensive library of gestures could be implemented in addition to mouse could be implemented in addition to mouse movement and mouse clicks. movement and mouse clicks.

Typical multitouch gestures, such as zooming in and Typical multitouch gestures, such as zooming in and out, as well as novel gestures, such as balling one’s out, as well as novel gestures, such as balling one’s fist are all possible. In addition, the use of multiple fist are all possible. In addition, the use of multiple laser beams would allow for recognition of a wider laser beams would allow for recognition of a wider range of free hand motions, enabling novel gestures range of free hand motions, enabling novel gestures that the hardware mouse cannot support. that the hardware mouse cannot support.

We implemented a fully functional working We implemented a fully functional working prototype system of 'Mouseless' that costs prototype system of 'Mouseless' that costs approximate $20approximate $20
