| 21 | SYSTEM AND METHOD FOR SEMI-TRANSPARENT DISPLAY OF HANDS OVER A KEYBOARD IN REAL-TIME | US12390679 | 2009-02-23 | US20100214226A1 | 2010-08-26 | Douglas Stuart Brown; John Falk Kelley; James Robert Rudd; Robert J. Torres |
| A method for displaying a virtual keyboard with a semi-transparent overlay of an end user's hands. The method begins by receiving a video signal comprising an image of a keyboard and at least one hand belonging to the end user. Next the method creates a virtual keyboard comprising an outline for each key residing in the image of the keyboard. After creating the virtual keyboard, the method sends to a computer screen the virtual keyboard overlaying on top of the image of the keyboard. The overlaying giving an appearance that keys residing in the image of the keyboard obscured by the end user's hand are now visible. | ||||||

| There is provided a typing game machine which may change a display mode of a predetermined character array to be displayed. For example, the predetermined character array is partially or totally non-displayed upon satisfaction of a predetermined condition such that the player may type characters by guessing non-displayed part of the character array. And the predetermined character array is partially or totally replaced by a group of selective character arrays being composed of a plurality of candidate character arrays such that the player type characters in referring to the candidate character arrays. Since such display modes are available, the player may enjoy the game in addition to the typing practice. Further, the skilled player can enjoy the typing game with this typing game machine. | ||||||

| Device for detecting a pressure force exerted by a human muscle. If a sensor measures that a defined force is exceeded, a signal is emitted. This signal is used to indicate to the relevant person that he needs to modify his behavior. To determine the teaching effect of this signal, it is proposed for these signals to be stored in a memory and for the stored values to read out after a certain time and compared with more recent signals. The device can be used, inter alia, in a writing instrument which measures both the gripping force on the writing instrument and the writing pressure. | ||||||

| A system and method for teaching proper hand positioning for using a keyboard. The system includes not allowing a lesson for learning to operate the keyboard to begin until home keys are depressed simultaneously. Additionally, the lesson will be interrupted periodically and will not continue until the home keys are depressed simultaneously. | ||||||

| An apparatus for teaching efficient typing comprises a glove (10) having a wristband (14), a backhand section (16) adjacent the wristband, a plurality of finger sleeves (18) adjacent the backhand section and having an opening at a distal end for exposing a fingertip, and a plurality of visually different finger codes (28) extending from said finger sleeves toward said wristband, and a keyboard (12) bearing key codes that visually correspond to the finger codes. | ||||||
| 27 | Environmentally safe machine control security switch | US858919 | 1997-05-19 | US5785439A | 1998-07-28 | James H. Bowen |
| A keyboard where no finger pressure is needed to input data, that uses rows of emitters opposed by rows of detectors to detect a finger position, that is environmentally sealed, and inherently intrinsic safe. The keyboard has a mouse function so an operators finger can be tracked to position a cursor on a host display, and input normal keyboard functions. A sleep mode for a display or keyboard that slows down the scan rate and emitter intensity to increase emitter life. A split keyboard for each hand with an arm rest with an arm strap to attach the keyboard to an operators arm and a strap to attach the keyboard to the arm of a chair. A learning keyboard with a mode for QWERTY or other key pattern keyboards that the position of the operators fingers are tracked and supper imposed on a display, so the operator can see when their finger is over the correct keyboard indicia so correct data entry can be made without looking at the keyboard. | ||||||

| Training apparatus for use with a keyboard comprises a rigid support and a stabilizing bar having optional hand guides. The stabilizing bar is attached to the support, preferably pivotably, such that, when said training apparatus is positioned in front of a keyboard, an operator's hands are positioned between but not touching the support and the stabilizing bar when the operator's fingers are positioned over their home keys on the keyboard. In an alternate embodiment, the support for the stabilizing bar is formed integrally with the keyboard support. | ||||||

| 30 | Keyboard Cover | US145580 | 1993-11-04 | US5419704A | 1995-05-30 | Marilyn A. North |
| A keyboard training aid has a support resting on the keyboard around the text entry keys and an opaque cover pivotally mounted on the support. The cover extends over the text input keys so that they cannot be seen by a training operator. Two apertures in the top cover are aligned between the keyboard operator and the home keys in the center row so that the home keys can be viewed. | ||||||

| A student learning to use a keyboard device is given brief instruction and then uses the keyboard. The instruction includes a final predetermined key or keyboard element manipulation, which completes instructions to signal the initiation of new instructions. The instructions and operational signals can be recorded together on a two-track record, such as magnetic tape, so that the instructions are coordinated with the system actuating signals. The system is manually started and introductory material is presented from the record. After instructions are given, a signal starts a clock to measure the elapsed time for performance of instructions. The clock is terminated by a system actuating signal following execution of the last instruction. In the preferred system, actuation of the predetermined key will initiate the record drive which will be stopped after each unit of instruction is given by an appropriate signal on the other track, different from the ones actuating the clock. Thus, student controlled responses combined with accurate timing of the activities completed is achieved. | ||||||
| 32 | Transcriber having selectable word reproduction rate | US731462 | 1976-10-12 | US4093831A | 1978-06-06 | Walter M. Sharp; Gary E. Bergstrom |
| The invention is a device for controlling a sound reproduction transcriber which provides alternate playback intervals and stopped intervals. The playback interval length in words and the average word reproduction rate are manually selectable by a secretary or instructor. The device meters the reproduced words during the playback interval and initiates the stopped interval at the first audio pause after the selected number of words have been played back. The required total cycle time is computed by effectively dividing the number of words played back during the playback interval by the selected average word reproduction rate. A timer, which counts the time elapsed since the playback interval was initiated, has its counted time compared to the computed total cycle time so that the stopped interval is terminated, the circuit is reset and the playback interval is again initiated upon coincidence of the computed time and the elapsed time. | ||||||
