Abstract

The article describes a small device that can be wore around the pointing finger of a person using a computer device. Using his/her pointing finger (that is wearing the fingertip mouse) the user can control the mouse pointer on the screen and click on the screen using the button on the tip of the device, thus interacting with the screen of the computer instead of a none related device.

Wearable fingertip mouse

The solution presented herein eliminates the need for a conventional mouse device to control the cursor on a computer screen (laptop, tablet, or PDA). Today there are many alternative solutions to the problem, such as keyboard integrated controlling devices (IBM's* "red stick" or the touch pad), hand-held track balls, and a touch screen by which one can move the cursor by pressing on the screen itself.

    Though these devices solve the problem, they all have drawbacks that have prevented them from penetrating the market and replacing the conventional mouse device. First of all, the touch screen is a very expensive device, and the hand-held track ball is very bulky, takes up the entire hand, and is quite hard to wear and take off. As for keyboard integrated devices, they are common in laptop computers but require much precision to operate and lack user direct interaction with the screen of the computer. Lately another solution has appeared, one that can come close to the one presented here: the video camera tracking device that uses a video camera to track an object. It is worn around the hand of the user, and when the user moves his/her hand it moves the cursor on the computer screen according the hand movements. This solution needs fine tuning and requires multiple video cameras to operate.

    The solution presented here is a small device that can be worn around the pointing finger of a person using a computer device. Using his/her pointing finger (which is wearing the finger-tip mouse) the user can control the pointer on the screen and can click on the screen using the button on the tip of the device, thus interacting with the screen of the computer instead of a non-related device.

    This solution avoids all the above listed drawbacks by introducing a slim, wearable controlling device that does not interfere with the wearer's work. It avoids the high price of the touch screen and virtually transforms any regular monitor into a touch-screen monitor. It does not have the bulkiness of the hand-held tracking ball, and it needs little tuning and no additional hardware (unlike the multiple video cameras). It can be used to conduct presentations without the bulky tracking ball and can be used to replace touch pads or mouse sticks in portable computers and even to replace the pen in tablets and PDA devices.
