Abstract
The present invention relates to a scan type tactile display, the pin (100) having a latch (110) to be caught on the wire 120 while being able to move up and down to feel tactile, in a vertical direction with the pin (100) Wire 120 is fixed in a fixed position, the separator 130 for separating the wire 120 from the clasp 110, the pin driver 150 to move the pin 100 once separated to the intended position, the clasp ( 110 is coupled to the wire 120, the coupling device 140, the separating device 130 / coupling device 140 / frame 160 to secure the pin driver 150, the frame 160 to the wire 120 It consists of a linear driver 170 for linear movement in the direction of ().
In order to display tactile information on the pin 100 of a specific (X, Y) coordinate on the display plane, the linear driver 170 moves the frame 160 to the X position of the corresponding coordinate. The wire 120 is separated from the latch 110 by the separator 130 fixed on the frame 160 just before arrival of the X position, and thus the pin 100 may be controlled by the pin driver 150. do. At this time, if necessary to drive the pin driver 150 in the Y position to display the intended tactile information by the pin 100 to move the frame 160 a little more, the latch (140) by the coupling device (140) As the pin 110 is caught by the wire 120, the pin 100 may be fixed to transmit tactile information to the user.
Description
Braille Displays, Graphical Tactile Displays, Miniature Drivers
White cane is the most commonly used tool to help the visually impaired walk. This cane is used to tactilely identify features and to walk around obstacles or dangerous objects. However, with this cane, you can only see features that are about 1m away, and you can't respond to other obstacles by grasping obstacles that are harder to see through tactile touches. This high level of walking requires a visual aid that can be remotely searched.
However, the task of commercializing such visual aids is slow. The key reason starts with the problem of the device itself that needs to be supplemented with the sense of touch. To tactilely inform, you need a driver that can deliver power, and it costs a lot to have a minimum of hundreds to even tens of thousands of drivers that can complement long-range vision.
To reduce the number of drivers, a scan scheme is used to control the pin at a specific position as the pin driver moves. An important design point is that the pin must be able to maintain the specified position after the pin driver has passed. The existing patent (US6700553) uses a pin with a clasp and an elastic wire. When the pin is pushed up to display information on the pin (ON means the pin protrudes and OFF means the pin is inserted), the elastic wire It contracts momentarily, catches up with the latch, then stays in the groove and retains the information. If the adjacent pins sharing the wire are turned on at the same time, the clasps of the two pins will pass through the wire at the same time, causing severe wire wear and high output of the driver. In addition, since there is no way to turn off the pin individually after turning the pins on, there is a separate OFF plate that turns off the entire display at once.In this case, the display efficiency is lowered, but the manufacturing cost is increased due to the additional components such as the OFF plate. . For example, in the case of the center pin, only 50% of the time is used to display the correct information, and the remaining time remains off.
The patent proposes a tactile display that is economically constructable and portable enough to be used in such a visual aid.
