Abstract
Abstract A device, which sits on a finger or the fingertip and allows communication with computer systems by finger-pointing to monitor images. Embedded into a body (10) are electronic elements, e.g., (11) and (9). Pointing with the finger to a certain image displayed on a monitor's screen causes the electronic elements to return a signal to the controlling software application through hardware interface electronic. The software application recognizes which of the displayed images has been selected by finger-pointing. The software application than starts corresponding actions.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
159 words
A finger-fitting device, for communicating with a remote computer system by pointing to a monitor screen, comprising: (a) a body, shaped as a thimble to fit onto any digit of a human hand; and (b) a light detecting sensor incorporated in a tip area of said body for sensing a light-emitting spot on said monitor's screen for causing a change in an electrical output signal of said sensor when said sensor in said body is brought in close proximity to the surface of said monitor screen of said computer system; and (c) a light transmitter incorporated in said body and connected to said sensor for detecting the change of said electrical output signal of said sensor and changing its transmitting state to provide a transmission signal to said remote computer system accordingly; and (d) an electric energy means incorporated in said body comprising a battery and a switch for providing electric current to said sensor and said light transmitter.
Claim 2
Dependent Claim
159 words
A finger-fitting device, for communicating with a remote computer system by pointing to a monitor screen, comprising: (a) a body, shaped as a thimble to fit onto any digit of a human hand; and (b) a light detecting sensor incorporated in a tip area of said body for sensing a light-emitting spot on said monitor's screen for causing a change in an electrical output signal of said sensor when said sensor in said body is brought in close proximity to the surface of said monitor screen of said computer system; and (c) a light transmitter incorporated in said body and connected to said sensor for detecting the change of said electrical output signal of said sensor and changing its transmitting state to provide a transmission signal to said remote computer system accordingly; and (d) an electric energy means incorporated in said body comprising a battery and a switch for providing electric current to said sensor and said light transmitter.
Claim 3
Dependent Claim
161 words
A finger-fitting device, for communicating with a remote computer system by pointing to a monitor screen, comprising: (a) a body, shaped as a thimble to fit onto any digit of a human hand; and (b) a light detecting sensor incorporated in a tip area of said body for sensing a light-emitting spot on said monitor's screen for causing a change in an electrical output signal of said sensor when said sensor in said body is brought in close proximity to the surface of said monitor screen of said computer system; and (c) a radio wave transmitter incorporated in said body and connected to said sensor for detecting the change of said electrical output signal of said sensor and changing its transmitting state to provide a transmission signal to said remote computer system accordingly; and (d) an electric energy means incorporated in said body comprising a battery and a switch for providing electric current to said sensor and said radio wave transmitter.
Claim 4
Dependent Claim
