State of the art

The pointing devices have their origin in studies conducted at the SRI (Stanford Research Institute). A research center at the University of Estanford, where in 1963-64 sought methods of pointing and pointing ("Point and click") on a computer screen. The group It was directed by Douglas C. Englebart, the inventor of the mouse, and It was in 1970 when it was patented as a "Position Indicator X-Y for a display system. "

The Apple computer manufacturer included it standard on your computer Lisa and due to its appearance, the device It was quickly called Mouse ("Mouse"), name with which It has universally popularized.

The traditional mouse system is the ball system, which by means of an opto-mechanical system transforms the mouse movement in a series of digital codes that are collected by the computer.

The latest trends point to mice from optical sensor (without ball) and without cable ("Cordless"), which avoid the disadvantages of the traditional mouse. There are currently others Mouse derived pointing devices: track-ball-track-point; pad  touch (touch pad); optical pencil; Tablet digitizer

In publicly accessible computer equipment, the most extended pointing device is the touch screen or Touch Screen, in this system the device monitor itself serves as support to a special surface and whose operation is performed by direct finger contact on the screen of said monitor.

Explanation of the invention.

The Invention Patent referred to in This Report is intended to guarantee exploitation and exclusive property throughout the national territory, of a electronic touch pointing device for computer equipment, which unlike other pointing devices, in which it is necessary a physical contact with the device itself, allows its use through glazing.

The device, object of the patent and whose functional blocks are illustrated in drawing 1 , is composed of a panel of six capacitive touch sensors in which each sensor circuit activates its output terminal when it detects the proximity of a finger at a distance maximum of 25 millimeters, on a metal surface connected to the input terminal of said sensor circuit. Four of these sensors represent, respectively, the up, down, left and right movement of the pointer on the screen and the remaining two sensors represent the functions of the buttons (left and center or right) of a conventional Mouse. The output terminals of the sensor circuits are connected to the input terminals of a microcontroller integrated circuit which, by software, determines which panel sensor has been activated to generate in its output terminal, a digital code that corresponds to the direction of travel of the pointer on the screen or at the press of any of the buttons.

The output of the microcontroller circuit is communicates with the receiving computer through a port communications that can be by RS-232 serial cable, USB or via wireless radio frequency communication, Bluetooth or infrared light.

The integrated circuit operation software microcontroller is stored in the ROM type memory that incorporates said microcontroller. This programming is done in The production phase of the touch pointing device for equipment computer. The device power supply is carried out at through an external rectifier transformer, with input of AC 220 V / 50 Hz and output 9 V / 500 mA in current continuous, connected by cable to the device.

Applications and advantages

The tactile pointing device for computer equipment provides a new means of interaction between the public that visits the outer side of a shop window, display or glass panel, of a commercial premises, office or office, and a computer installed on the inner side of said glazing , with its screen visible from the
Exterior.

The numerous applications of the device Touch pointer for computer equipment are inherent to those of A public access computer. Some of these applications would:

- Information point.

- Interactive advertising in shop windows.

- Public internet access.

- Entertainment.

The touch device pointing device IT does not suffer deterioration in its structure or its hygienic conditions since it remains inside the premises, In addition to lacking mechanical buttons for its operation.

Method of realization

For the construction of the pointing device touch for computer equipment the following have been used elements:

A closed plastic enclosure that determines the physical appearance of the device and contains the printed circuit inside (see drawing 2 ).

One of the outer faces of the enclosure has the functions of moving the pointer and the buttons in the touch-sensitive areas corresponding to the sensitive metal areas of the printed circuit printed (see drawing 3 ).

Said outer face is fixed to the glass or plastic material by means of an adhesive film, at the time of Device installation.

A printed circuit where they are fixed and interconnect the electronic components necessary for your functioning.

A set of active electronic components and liabilities

Claims (1)

1. Touch pointing device for computer equipment whose operation is characterized by the absence of physical contact between said device and its user. By activating with the finger the respective inductive touch sensors that said device incorporates, through the glazing of a shop window, showcase, display or window on whose inner face said device adheres, the movement of the mouse pointer on the screen is achieved and / or the emulation of the functions of the Mouse buttons.
