Definitions

  • the invention relates to a device for the rapid input of information to a computer according to patent claim 1 and a corresponding method for this according to patent claim 50.
  • a text input system which uses a touch screen. All letters and the most common words are displayed as keys, which requires 92 keys. The keys are arranged alphabetically, which is proven to be inferior to a frequency-based arrangement (M. Heiander (ed.), Handbook of Human-Computer Interaction, Elsevier (1988), p. 479). A dictionary list is also displayed. Approx. 12 x 20 cm are occupied on a monitor, which delicately limits the applications on mobile devices. In addition to the keys, the vowels can also be entered using so-called 'flicks' or line directions.
  • a user interface device which uses a stylus for input.
  • the 'graphical keyboard' has, among other things, a key arrangement known as the QWERTY keyboard.
  • the graphical keyboard is able to use the letters already typed e.g. perform the ALT or CONTROL function.
  • two 'strokes' can be connected to e.g. to be able to enter the letter a in capital letters with CONTROL-A. Use for the disabled, e.g. for blind writing, or in rehabilitation in general is not provided.
  • Some touchscreen devices offer handwriting recognition, but unfortunately this does not work optimally. There are those who try to decipher whole words and others who enter letters by letter by hand. The letters must be entered using a special 'graffiti' alphabet (U.S. Robotics, Palm Computing Division, Los Altos, California U.S.A.). The device often misinterprets the handwriting, which means that the user is distracted from the actual writing process. Another problem with these devices is the complex programming, which requires storage space and computing capacity, with the result that the entered text is displayed with a delay. In the Palm device, there is no separate use of the input device and the output device, which makes many useful applications impossible.
  • a folding keyboard is described in US Design Patent No. D457.525 S, in which no wireless connection to the output device is provided. Like a normal keyboard, the folding keyboard has the disadvantage that for entering from Example words or program commands that fingers and hands have to make relatively large and large movements. Many cases of RSI (Repetitive Strain Injury) are due to the (intensive) use of computer keyboards.
  • RSI Repetitive Strain Injury
  • a rapid writing system and device which has consonant keys and a vowel key. From each key, a pen can be moved in one of eight directions. These line directions can be freely combined for text input. However, there are no applications in which the text can be entered separately from the display device. Since it is primarily a writing system, the functions such as e.g. CONTROL or ESCAPE, as they are known for a computer keyboard. In addition, the use of the writing system for devices with physical keys is not intended.
  • an "electronic musical instrument in connection with computer” is known.
  • a computer is connected via a cable connection to a keypad, the keys of which are arranged on the X / Y axes.
  • Music sounds can be generated and set by entering the keys.
  • It also has pedals with which volume and echo effects can be influenced.
  • There is no wireless connection to the computer and no possibility of a force feedback function. Input variants for electronic sound generation have been described in detail (P.Gorges, L. Sasso, Nord Modular, Bremen, 2000).
  • the object of the present invention is to propose a device for the rapid input of information to a computer, which has access to the complete functionality of a computer keyboard and a computer mouse or a similar interface and a music keyboard with function keys and various sliders, combined in the smallest space and thus avoids the disadvantages mentioned. Another task is to specify a corresponding procedure for this.

  • Input detection unit 20 has three ultrasound receiver modules 39, 39 ′ and 39 ′′, the strength of the input signal being measured in each of them and ultimately the amount of data M being determined again.
  • this arrangement is not limited to three ultrasound receiver modules.
  • the exemplary embodiments described allow input that is efficient, comfortable, practical and flexible, in particular if it is carried out wirelessly. When using eight line directions, the number and the resulting combination possibilities result in an optimal input sentence. It enables access to the complete functionality of a PC without additional input means and / or peripheral devices but always with the same input method. The functionality of writing, painting, music, internet surfing etc. there the hands do not have to be moved, which is advantageous in tight spaces.
  • the solution according to the invention is particularly distinguished for mobile devices, since many functionalities are accommodated in the smallest space requirement.
  • Rapid input devices are used in the rehabilitation and reintegration of disabled people, e.g. for people with a quadriplegia or for the blind.
  • the at least one input means in the at least one input acquisition unit coordinates at least one point
  • Input acquisition unit has already been described in FIG. 1.
  • the coordinates of two points P1 and P2 are generated using two input means in two input detection units (FIG. 4).
  • a wide variety of input means are used in the exemplary embodiments described: one or more, the same or different.
  • the coordinates of the at least one point P are converted into electrical signals in the at least one input detection unit 20 (US 5,028,745 (Position Detecting Apparatus), US 5,466,896 (Position Detector)).
  • a third step at least one data quantity M is formed from the electrical signals measured over time.
  • the third exemplary embodiment (FIG. 4) reference was made to the formation of two data quantities M1 and M2, which are each fed to the computer 30 via a cable connection.
  • the data sets M1 and M2 are processed in the computer in such a way that a new data set M is formed from them, which now correspond to points P (x, y, z, t).
  • the amount of data M is transmitted to the computer 30 wirelessly (WO 01/18662: Wireless Peripheral Interface with Universal Serial Bus Port) or via a cable connection.
  • the amount of data M is processed in the computer 30 by means of data processing and kept available for output means.
  • Output means, in their diversity, are not described in detail here.

Abstract

L'invention concerne un dispositif de saisie rapide comportant au moins un élément de saisie (10), au moins une unité d'enregistrement de saisie (20) et un ordinateur (30), la position spatiale de l'élément de saisie (10) définissant au moins un point (P) dont les coordonnées sont converties en signaux électriques dans la ou les unités d'enregistrement de saisie (20) et forment dans le temps au moins une quantité de données (M) à partir des points (P), et forment par conséquent la saisie. L'unité d'enregistrement de saisie (20) est connectée (25) à l'ordinateur (30), ledit ordinateur comportant des éléments de traitement de la ou des quantités de données (M). La connexion (25) s'étendant de l'unité d'enregistrement de saisie (20) à l'ordinateur (30) est réalisée sans fil ou à l'aide d'un câble. Le dispositif de saisie rapide selon l'invention est mobile et peu encombrant. L'invention concerne également un procédé d'utilisation dudit dispositif ainsi que son utilisation dans des appareils d'écriture, des applications informatiques générales et la réhabilitation.
