Abstract
Description
Tast- grijphulp met objectinformatie voor blinde mensenTactile help with object information for blind people
De uitvinding voor blinde en slechtziende mensen heeft betrekking op het grijpen van allerlei objecten. Tevens kunnen met het gebruik van de tast- en grijphulp 5 obstakels vermeden worden.The invention for blind and partially sighted people relates to grasping all kinds of objects. Obstacles can also be avoided with the use of the probing and gripping aid.
De uitvinding wordt via een elastische band over de vingers op de handrug geschoven. Bovenop de elastische band is een afstandssensor geplaatst die een gebied kan aftasten van bijvoorbeeld 1 meter en bij nauwkeurig aftasten van bijvoorbeeld een Vi meter. In de elastische band, opzij van de afstandssensor, zijn 6 prikkel- puls- of 10 trilpads geplaatst die bij de werking voelbaar zijn op de handrug. De genoemde pads zijn, naar gelang men het object nadert, voelbaar oplopend van de pols naar de vingers. De afstand ver weg van het object betekent het trillen van een pad aan de kant van de pols en de afstand dicht bij het object (grijpafstand) betekent het trillen aan de kant van de vingers. Om het object te vinden maakt de blinde met de arm horizontale en verticale 15 bewegingen zodat een van de 6 pads gaat trillen en hierdoor de afstand bepaald wordt.The invention is slid over the fingers on the back of the hand via an elastic band. A distance sensor is placed on top of the elastic band which can scan an area of, for example, 1 meter and with accurate scanning of, for example, a Vi meter. In the elastic band, on the side of the distance sensor, 6 stimulus, pulse or 10 vibrating pads are placed which can be felt on the back of the hand during operation. The aforementioned pads are noticeably ascending from the wrist to the fingers as you approach the object. The distance far away from the object means the vibration of a path on the wrist side and the distance close to the object (gripping distance) means the vibration on the side of the fingers. To find the object, the blind man makes horizontal and vertical movements with the arm, so that one of the 6 pads vibrates and the distance is determined by this.
Tussen de duim en de wijsvinger zit een schakelaar op de elastische band. Een keer indrukken betekent aan voor 1 meter afstand en twee keer indrukken voor een x/i meter en drie keer indrukken betekent apparaat uit. Bediening geschiedt door de duim tegen de bovenkant van de wijsvinger te drukken.There is a switch on the elastic band between the thumb and the index finger. Press once means on for 1 meter distance and press twice for x / i meter and press three times means device off. Operation is by pressing the thumb against the top of the index finger.
20 Aanvullend wordt een minicamera op de elastische band naast de sensor geplaatst die gericht is in dezelfde richting als de straal van de sensor. Deze camera staat in verbinding met een palmcomputer. Aan de palmcomputer zit vervolgens een oortelefoon.Additionally, a mini camera is placed on the elastic band next to the sensor that is directed in the same direction as the radius of the sensor. This camera is connected to a palm computer. An earphone is then attached to the palm computer.
Als een blinde een object aftast en deze via de pads vindt, tast de camera dit 25 object af en vergelijkt dit in een database van objecten en voorwerpen in de palmcomputer en geeft de gevonden informatie door via de oortelefoon aan de blinde.When a blind person scans an object and finds it via the pads, the camera scans this object and compares it in a database of objects and objects in the palm computer and transmits the information found to the blind person via the earphone.
De uitvinding zal hieronder nader uiteengezet worden aan de hand van figuren die de werking en uitvoeringsmogelijkheden van de vinding weergeven.The invention will be explained in more detail below with reference to figures showing the operation and possibilities of implementation of the invention.
30 Fig. 1 geeft een zijaanzicht en een bovenaanzicht van een inrichting met een elastische- of klittenband 1, die over de vingers 9 geschoven wordt op de handrug 8. Boven op de band 1 komt een afstandssensor 2 en in mijn voorbeeld 6 pads 3a t/m 3f welke geplaatst worden langs de afstandssensor 2. Deze pads 3 zijn oplopend van pad 3a van de pols 10 naar de pad 3f van de vingers 9.FIG. 1 shows a side view and a top view of a device with an elastic or velcro strap 1, which is slid over the fingers 9 on the back of the hand 8. On top of the strap 1, a distance sensor 2 and in my example 6 pads 3a to 3f are placed which are placed along the distance sensor 2. These pads 3 are ascending from pad 3a of the wrist 10 to the pad 3f of the fingers 9.

Als het niet mogelijk is om een batterij of accu 14 op de band 1 te plaatsen kan deze geplaatst worden op een aparte band 5 met hierop een batterij of accu 14 die geplaatst is op de onderarm 11. Deze maakt verbinding met een bedrading 6 met de afstandssensor 2. Tussen de duim en wijsvinger 7 zit een schakelaar 4 op de elastische-5 of klittenband 1 die met de duim bediend wordt. Bijvoorbeeld bij eenmaal drukken wordt de afstandssensor 2 ingesteld op een halve meter, bij tweemaal drukken op een meter en bij drie maal drukken wordt de afstandssensor 2 uitgezet.If it is not possible to place a battery or accumulator 14 on the strap 1, it can be placed on a separate strap 5 with a battery or accumulator 14 placed on the forearm 11. This connects to a wiring 6 with the distance sensor 2. Between the thumb and index finger 7 there is a switch 4 on the elastic-5 or velcro strap 1 which is operated with the thumb. For example, once pressed, the remote sensor 2 is set to half a meter, when pressed twice to one meter and when pressed three times, the remote sensor 2 is turned off.
In fig. 2 wordt aangegeven dat door middel van horizontale en verticale bewegingen van de arm de straal 12 van de afstandssensor 2 het object 13 raakt en 10 voelbaar wordt door een van de pads 3 en hierdoor de afstand naar het object 13 ingeschat kan worden. Als het object voelbaar is wordt de hand naar voren bewogen en kan het object gepakt worden als pad 3f voelbaar is.In Fig. 2 it is indicated that by means of horizontal and vertical movements of the arm the radius 12 of the distance sensor 2 hits the object 13 and can be felt by one of the pads 3 and as a result the distance to the object 13 can be estimated. If the object is palpable, the hand is moved forward and the object can be caught if pad 3f is palpable.
