DE2263332A1 - AUDIO-VISUAL SENSORY DEVICE FOR THE EFFICIENT LEARNING OF ACTIVITIES TO BE TOUCHED WITH SEVERAL FINGERS - Google Patents

Description

Title: "Audio-visual-sensory device for the rational learning of activities to be carried out with several fingers" Patent description The learning of skills in which the fingers play an essential role, such as typing, playing the piano, programming devices etc. cultural, especially in the musical area of human life an important place. That is why new methods have been developed to shorten the lengthy and arduous learning time.

The currently most modern method is the audiovisual, which gives the student a combination of acoustic and optical information. The basic disadvantage that characterizes both the classical and the modern audiovisual teaching system is the fact that, in order to obtain a movement of the fingers, they use optical and acoustic commands which contain the actual information encoded form and must first be decoded by the student.

This is laborious and always has a more or less long response time between the arrival of the command and its execution accompanied5 The present The invention therefore describes a device, hereinafter referred to as "fingermaster, which gives the movement to be performed directly to the fingers as a sensory command. In Combination with acoustic and optical signals makes it a logical one Further development of the audiovisual to the audiovisual sensor system (A.V.S.) the.

According to the invention, one sits at the physiologically favorable points every finger little stimulator (1). These are set by a programmer (2) activated in the order of an entered program and thus solve the desired movement of the finger, the same programmer assigns each finger stimulation on one Display screen (3) an optical and - with headphones # (4) - an acoustic signal too. All three signals can be used at the same time or else given with the correct time shift.

The display screen (3) provides a meaningful picture of what is to be operated Device (5). If the finger hits the right key or string after stimulation us. if it lights up on the display screen e.g.

green, if it does not hit it, it lights up red. Simultaneously a signal sounds through the headphones, e.g. "wrong". This correction is carried out according to the invention accomplished by a comparator (6), which the actually operated control element compares with the one commanded in the program.

In the case of a typewriter keyboard, the finger can in principle assume four misalignments: too high, too deep, too far to the right or to the left. According to the invention there is a passive resonator (7) with a fixed natural frequency on each finger. It comes into resonance with the active oscillator, which oscillates at the same frequency (8) on the correct key. According to the invention, each finger is assigned a frequency, which is automatically given by the programmer (2) to the key to be printed. the surrounding keys automatically receive slightly different frequencies in such a way that that the comparator (c) can decide on the basis of the different attenuation, whether the finger is set too high, too low, to the right or left of the key to be pressed became.

In addition to the optical and acoustic correction, the comparator gives according to the invention auc. a sensory correction. For this purpose, e.g. left on both sides and on the right of the wrist and on the front and back of the upper arm on the Small stimulators (9) attached to physiologically favorable places. The comparator (6) operates it in such a way that an obvious corrective movement is carried out will, The stimulators (1) (9) as well as the pessive resonators (7) - mitsaint their electrical connections - are according to the invention in two easy to carry Gloves housed.

Claims (1)

Claims 1.) Device for learning the technique of operating finger-operated devices Devices, hereinafter referred to as fingermasters, d u r c h e k e n n -z e i c h n e t that stimulator n placed on each finger of the student are, which are controlled by a programmer so that the finger to be operated receives a sensory stimulus that triggers the desired movement, where possible positional errors due to frequency assignments of passive resonators with a defined natural frequency on each finger to the one controlled by the programmer, high-frequency oscillators located in the keys by means of a comparator recognize which sensor, optical and acoustic corrections are being made, until the position of the finger corresponds to the desired 2.) Fingermaster device, according to claim 1) that the stimulators are electrical, electromagnetic, mechanical or thermal in nature and in the form of pleasantly perceived stimuli triggering the desired movement. 3.) device fingermaster, according to claim 1) d a d u r c, h g z k 8 n n -z e i c h n e t that the comparator the vibration damping resp. Resonance oscillation between the oscillator frequencies of each Measures keys and the passive resonators with a fixed natural frequency on the fingers and based on this information sensory, optical and acoustic corrections controls. 4.) Fingermaster device, after request i) d u r c h e k e n n n -z e i n e t that the display screen the commands of the programmer in obvious converts optical signals and the comparator confirms the correct or incorrect Gets execution and converts these into obvious signals. 5.) device fingermester, according to claim 13 and 4) d a d ur c h g 0 k E n n z s h e n e t that the programmer every imaginable, meaningful program can be stored that he can then either simultaneously or with any time shift in the form of sensory, optical, and acoustic Transmits stimuli to the student. 6.) device fingermaster, according to claim 1), 3), 5) d a d u r c h g e -k e n n n e i c h n e t that the headphones, controlled by the programmer, have a provide meaningful acoustic information and, in the event of a student's error, a acoustic correction command is given. 7.) Fingermaster device, according to claims 1), 3) d a d u r c h g e k e n, n -z e i c h n e t that the passive resonators can be addressed acoustically or electrically are.
