#TECHNOLOGY FOR MOUSELESS CLICKING FREE#

Although it is not expensive to realize, it offers advanced gestural usage, and its usage is intuitive to all who have used an ordinary computer mouse, there are still some issues that need to be solved. An image of the human hand is read from the webcam and the hand. Mouse operations like left click, right click and double click are performed by hand gestures. There are no plans for commercializing the “invisible mouse” but the prototype Mouseless was built for around $20 USD. In this paper, an approach for developing an intangible interface with the help of computer vision technology for human computer interaction using static hand gestures has been discussed.

The researchers claim that the use of multiple laser beams would allow the recognition of a wider range of free hand motions, enabling novel gestures that the hardware mouse cannot support.

Typical multitouch gestures, such as zooming in and out, as well as novel gestures, such as balling one’s fist are all possible. When the user taps their index finger, the size of the blob changes and the camera recognizes the intended mouse click.Īs they improve their computer vision algorithms, an extensive library of gestures could be implemented in addition to mouse movement and mouse clicks. As the user moves their hand the cursor on screen moves accordingly. The change in the position and arrangements of these blobs are interpreted as mouse cursor movement and mouse clicks. The IR camera detects those bright IR blobs by using computer vision. The user cups their hand, as if a physical mouse was present underneath, and the laser beam lights up the hand which is in contact with the surface. The laser beam module is modified with a line cap and placed in a way so it creates a plane of IR laser just above the surface the computer sits on. Although keyboard equivalents for many mouse functions exist, the question remains as to whether they are usable in practice, without having to rely on mouse emulation software. Toolbars, which are not easy to access by keyboard, are now ubiquitous. Both IR laser and IR camera are embedded in the computer. The 'shortcut menu,' for example, is activated by clicking the secondary mouse button on a screen object. Mouseless consists of an Infrared (IR) laser beam (with line cap) and an Infrared camera. The Mouseless invention removes the requirement of having a physical mouse altogether but still provides the intuitive interaction of a physical mouse that most of us are familiar with.
