LT5157B - Computer mouse for the blind - Google Patents

Abstract

Computer mouse for the blind relates to computers and can be used for teaching purposes of the blinds. Computer mouse for the blind comprises a rectangular holder (1) with rings (2) and rollers (3); a magnet (4) is disposed in a frame of a mouse; a system is placed on an axis (5), which is fixed in a frame of a mouse and is coaxial with horizontal axis; an axis of magnets are parallel to axis of a folder (1) and of a frame. Rigid plates (6, 7) are fixed at a top and a bottom of a holder (1), magnets (4) are placed with contact on surfaces of rings (2) and can to move in horizontal direction; a winding (8) is placed on magnets (4). A cavity (9) is made in a top of rollers (3). Rings (2) and roller (3) a re fixed motionlessly.

Description

The invention can be classified in the field of a computer device adapted for working with a computer for the disabled.

Known tactile screens for the blind to work with the computer. These are sophisticated video and text transmission mechanisms. They have one needle per actuator, making the device bulky and cumbersome (see Taylor, PM, Hosseini-Sianaki, A., Varley, CJ: An Experimental Investigation into the Application of Electrorheological Fluids in Tactile Display Systems, Proc. 5th International Conference on Adaptive Surfaces, Sendai, Japan, December 5-7, 1994.)

The disadvantage is the complex and bulky device.

A similar computer mouse device with an electromagnetic transceiver is known (see International Patent US 5870080 G06F 3/033). This device combines a computer mouse and an electromagnetic transmitter-receiver. They are connected to the computer's data bus. Transmitter - Receiver receives information via electromagnetic pulses from a device with appropriate equipment and at a sufficient distance, converts pulsations into electrical signals and transmits these electrical signals to a computer. The receiver receives electrical signals directed to the device from a computer, converts electrical signals into electromagnetic pulses and transmits pulsations to a remote device. This ensures the interface of the specific device, away from the computer, with the database.

The construction of this unit is very complicated. There is also a lack of communication.

The object of the present invention is to simplify the construction of the device and improve the transmission of information to the blind.

The computer mouse is made up of an outward rectangular holder with integrated rings and wheels inside the mouse and magnets incorporated into the housing, the system being mounted on an axis mounted in the computer mouse housing and coinciding with its horizontal axis and magnet axis. for housing axes. The top and bottom of the bracket are fitted with rigid plates and the magnets are positioned so that their surface is in contact with the surface of the rings and allows them to move freely in the horizontal direction, with the winding wrapped around the magnets. At the top of the wheels is a cavity for the upper parts of the wheels to protrude, which are intended to touch the finger. The rings and wheels are fixed together.

The essence of the invention is illustrated in the drawings.

Figure 1 is a sectional view of the main element mounted. Magnet 4 and rings 2 and casters 3 mounted on axis 5. Coil winding 8 on magnet 4.

In figure 2, the dashed line shows the cavity 9 in the holder 1 through which the top of the wheels 3 extends and comes into contact with the finger. All these elements are reduced on axis 5 and mounted in bracket 1.

Figure 3 shows the magnets 4 and the wheels 2 and 3 from the side. Visible form 4 magnets. Figure 4 shows a magnet 4 with a winding 8, rings 2 and wheels 3 wrapped thereon. The computer mouse consists of a rectangular holder 1 with integrated rings 2 and wheels 3 located therein, as well as magnets 4 mounted on the mouse. In addition, the system is mounted on an axis 5, which is mounted on the computer mouse housing and coincides with its horizontal axis, and the magnet axis is parallel to the axis of the holder 1 and the housing. At the top and bottom of the holder 1 are rigid plates 6 and 7, and the magnets 4 are arranged so that their surface is in contact with the surface of the rings 2 and can move freely in a horizontal direction. to roll out the upper parts of the castors, which are intended to touch the finger. Rings 2 and casters 3 are fixed together.

This device works as follows.

While the cursor passes through a white and non-communicating area on a computer screen (not shown), the pulse is not transmitted, but a constant signal is sent to magnet 4 and presses ring 2 and ring 2 is fixedly connected to wheel 3 which does not rotate. When text or graphic information is generated, a voltage cut-off signal is sent to the magnet. The voltage is interrupted by allowing the rings 2 and the wheels 3 to rotate for a set time. Wheel 3 touches finger and transmits information. This device significantly simplifies the design of this type of device and improves information transfer.
