Definitions

  • the "flexible computer input” described here is characterized in that it determines the final signals or characters for a computer from information about a basic position of the fingertips and from measurement data of a sensitive input surface on which the operating fingertips are located adapts individually and dynamically to hands and work habits.
  • the usual computer input keyboards require a discipline to hit the keys in certain lines and thus to maintain certain distances.
  • the input of data can be adapted to individual hands and work habits, because it is only about the basic existence of distances that can be changed and adapted individually and dynamically (or gradually) while working. This results in ergonomic advantages.
  • a quasi continuously extended touch-sensitive surface is easy and intuitive to use.
  • the "flexible computer input” described here consists (not of conventional keys, but) of a sensitive surface (ie an input surface consisting of a large number of input surface areas) and a software concept (ie a method).
  • the arrangement determines the characters (eg letter or control signals) especially in typing mode from the basic positions of the 10 fingertips ("basic topography") and from the completed printing locations. This means that due to the hand positions and hand movements or pressure triggering on a relatively smooth, sensitive input surface, the associated characters are obtained by comparison with a temporarily applicable "occupancy topography”.
  • the handling in relation to the basic topography
  • the handling is in the dynamic typing Mode, in particular, almost automatically adaptable to individual hand dimensions and typing habits, insofar as it makes ergonomic sense.
  • the sensitive surface can optionally also be used as a (large) trackpad, i.e. replace a mouse.)
  • a currently common touchscreen eg that of a "tablet PC”
  • a currently common touchscreen which basically can only differentiate between one pressure point at a time
  • can be upgraded with the appropriate software to include this flexible input system see also below, end of the description. It requires the user a certain discipline to put your fingers on one after the other.
  • a touchscreen for example that of a "tablet PC”
  • a flat sensor that can process several finger positions at the same time
  • Optical quality is somewhat deteriorated there by adding, for example, a fine sensor matrix, but is sufficient to display the occupancy topography.
  • small PC types usually don't have a conventional keyboard anyway, they can also use this ergonomically and individually adaptable, flexible input.
  • a relatively smooth sensitive input surface can be used as a separate keyboard or Input unit can be used to the computer.
  • a certain translucency of the surface is sufficient to display the occupancy topography (or the objects).
  • fine motor feedback e.g. are produced by the elasticity of the control surface with a certain cross-sectional profile (use of toggle lever effects) ("visualizing-touch-surface vision")
  • This "flexible computer input” is characterized, among other things, by the fact that the processor has a "basic topography" of the fingertips, from which a “occupancy topography” can first be inferred by scale-like projection, and that each measured pressure trigger location (or actuated input area) is compared with the temporarily applicable "occupancy topography”. From this relation, the intended sign either results directly. Or it may be necessary (e.g. if the sensitive input surface is only raster-meshed) to identify (by processor) the active finger and the associated character (or the associated command) can then be determined. This relation or identification to be queried relates primarily to the hand topography (or fingertip topography, shown as 10 circles in Figure 1).
  • Certain inputs which are processed by a microprocessor or a corresponding EDP unit, are used to trigger the signal for a specific character (e.g. alphanumeric or control characters).
  • a specific character e.g. alphanumeric or control characters.
  • the processor uses in particular the information (a) for triggering pressure or actuation of the input surface areas, (b) for identifying the location of the fingertips and (c) for the basic and occupancy topography.
  • the identification of the location of the print trigger on the sensitive surface leads, for example, to the location description using a grid of coordinates.
  • Such coordinates can be determined for several fingers at the same time, for example on the basis of a technically modified sensitive surface (possibly using two different sensitive methods, for example a video image of the contours).
  • the current positions of additional fingers can thus be determined.
  • An existing "5-wire resistance technology” could, for example, by a "6-wire resistance technology” Development and additional information about pressure point and finger positions. Development work may have to be invested in this, see below for technical feasibility. While the pressure triggering only has to be localized for one finger, the positions of the other fingers should be determined quasi-simultaneously or in one triggered query procedures (eg 5 times per second for the area) can be determined).
  • the processor always has a basic topography (or “template”) of the 10 fingertips available, which represents a basic posture of the hand.
  • This topography is in particular in the form of the coordinates of the 10 fingertips.
  • the topography can be defined individually for each user and, on top of that, it can be dynamically adjusted.
  • the (primary) basic topography results in a (secondary) occupancy topography that assigns certain characters to the input area areas.
  • the print trigger location (or the actuated input area) must be compared with the current, temporarily saved occupancy topography. From this relation, the intended sign either results directly. Or it may be necessary (e.g. in the case of indistinct work or if the input area is only roughly meshed) to optimize (by processor) the decision (compare below) or to identify the currently active finger (e.g. left hand, middle finger) and this is the reason then the associated character (or the associated command) can be determined.
  • the basic topography (or fingertip topography, shown as 10 circles in Figure 1) initially provides the basis for developing a secondary occupancy topography (secondary) through scale-like projection.
  • This occupancy topography can be described as sectors or input surface areas designated by coordinates which are assigned to a respective character or command location.
  • the basic topography covers or determines exactly the signs of the usual basic position (for the 8 non-thumb fingers these are traditionally "A, S, D, F, J, K, L, ⁇ ").
  • the next subsequent pressure point positions require a certain small deviation (shown as arrows in the drawing) in order to reach the corresponding characters. The direction of this deviation can be clearly separated for middle and ring fingers.
  • index finger and little finger must be distinguished more precisely because it (in the sense of the usual system) there are several options (compare drawing).
  • the thumb could be given a new role (eg important command functions) because it is actually underchallenged in the sense of the usual system.
  • the further assignments are to be assigned in the sense of the assignment topography (see points C. and D. below.)
  • a hand topography (with the adjustable limit values) always results in an occupancy topography.
  • This "flexible input” is optionally characterized in that the positions and pressure releases of several fingers are determined and evaluated simultaneously on a sensitive input surface (see claim 2). This enables easier and flexible adjustments for the individual user.
  • the "flexible input” mentioned here is characterized in that it not only determines the position of one finger, but the positions of several fingers (at the same time) and, based on the positions, movements and (more or less fast) pressure releases of one, two, three or up to ten fingers on a (relatively) smooth, sensitive surface generates corresponding control signals or determines associated characters.
  • the handling can be adapted to special tasks and thus be simplified, ergonomically sensible and “intuitively appropriate”.
  • the deviation is smaller than an (adjustable) limit (e.g. 7 mm).
  • the location is interpreted as the starting point of the finger. There is a certain character (e.g. for the left middle finger "D")
  • the deviation is greater than the limit.
  • the direction of the deviation is to be interpreted on the basis of the current template (in the sense of the starting position) as an activity associated with a specific finger. If the direction e.g. deviates more than 7 mm upwards from the starting point, there is the sign "E" above the middle finger of the left hand.
  • the (largely) uniformly drawn input surface should have a certain transparency, if possible, to use projections or LED elements to roughly represent the current template of the local occupancy (occupancy topography). This enables the user to coordinate finger movements with the eye for more distant or hard-to-remember assignments (e.g. for special characters or commands). - This corresponds to the following decision in the processor: An operation that hits the outer locations of the current template (special characters, commands and the like) is always interpreted as a hit of these special characters.
  • Any locations that are pressed simultaneously (with two or more fingers) can be decided in the processor according to predefined probabilities or priorities ("filter options").
  • the temporarily stored basic topography (as a primary reference) (and thus also the resulting temporarily stored occupancy topography as a secondary reference) can be determined in the following way:
  • the topography could also correspond to a simple straight-line grid in the sense of conventional standard keyboards. It can e.g. can be easily varied in their longitudinal and transverse dimensions.
  • the topography could also be ergonomically adapted to an average hand shape through curved lines, i.e. the assignments are grouped around an average relaxed hand. In particular, this corresponds to the different lengths and possibilities of movement of the 10 fingers (see Figure 1).
  • the topography can, in particular, be individually determined and saved for each user by relaxed laying on of the fingers and can therefore be called up.
  • all 10 fingers should be placed comfortably and calmly on the surface once (for example, for two seconds simultaneously as an initiating symbol for the calibration.
  • all 10 fingers should be typed one after the other roughly into the basic position for calibration.
  • a “scale topography” also results in the "occupancy topography", for example, in that the distances to the other lines of the “occupancy topography” are proportional to the distances between the fingertips of the “basic topography”” be determined.
  • Dynamic adjustment The topography (basic and occupancy topography) as well as the work parameters and limit values can be adjusted gradually or dynamically, especially while working. In other words, in this mode, the average location or pressure points realized by the fingers, ie the average basic positions of the 10 fingers or the occupancy topography, are continuously recorded. Any gradual shifts and possible gradual changes in the average line distances are noticed and corrected if necessary.
  • measurements can be taken five times per second and averaged over the last 20 seconds or averaged over the last 20 keystrokes of a certain input area).
  • the user can gradually vary their personal hand position, writing and typing habits.
  • several working parameters and limit values used by the processor can be changed gradually or dynamically (especially those to distinguish the geometric deviations from the basic position or, for example, to distinguish between deliberate pressure triggering from a strip that is too fast or from a support that is too static) ,
  • the average distance to the other occupancy lines and the average stroke impulses (time gradient) are determined and corrected if necessary.
  • the type of projection from a basic topography to occupancy topography can also be changed.
  • this input system is "capable of learning”. This arrangement makes 10-finger typing more attractive by adapting to natural hand shapes and individual movements.

  • the measurement data of all these elements changed by touching the fingers can be made available to the processor in a capacitive measurement in order at best to determine the position (to be distinguished from the pressure triggering) and in to calculate the pressure trigger determination (DruB) of several fingers in each case.
  • DruB pressure trigger determination
  • vapor-deposited conductor tracks and insulation layers can provide the feed to the point-like sensors.
  • the technical feasibility for the "touch-screen-like vision" can be established, for example, by replacing or superimposing certain visual pixels in the sensitive zone with pressure sensors (which act analogously to the force) (for example, every fifth pixel row would have every fifth Pixels or, for example, to replace an area of 2 by 2 pixels with a pressure sensor).

  • the measurement data of these elements changed by finger touching can be made available to the processor in a capacitive measurement in order at best to determine the position (PosB) (to be distinguished from the pressure triggering) and in any case the Calculate pressure trigger determination (DruB) of several fingers.
  • the computer input is optionally characterized in that the sensorium for simultaneous measurement of several finger positions e.g. can also be detected by an electric field that is built up in several directions (several times per second), that is to say quasi-circumferentially, (especially for two fingers). (Compare claim 11 and Figure 6)
  • the input surface is optionally characterized (cf. claim 5) in that it provides fine motor feedback for actuation or pressure release with a noticeable exceeding of a release force by using an elastic (if possible still translucent) surface with a certain geometric structure (the surface is supported by transverse, almost flat slender struts), which is characterized in that it uses the toggle effect and the buckling effect at the same time and can be produced in particular by an extrusion process.
  • the toggle effect and the buckling effect cause the resistance to rise to a certain maximum value when the pressure is actuated, and when this maximum value is exceeded, the resistance breaks down (because the slim cross struts buckle) and lets the surface sink in by a certain distance (eg by 3 mm) to trigger the control signal.
  • the technical feasibility of position determination (PosB) and actuation or pressure release determination (DruB) of several fingers with fine motor feedback thus exists, for example, by the following suggestion:
  • the input surface (the “touch field”) is structured as follows: the one on the upper side is relatively smooth Surface is made of an elastic and transparent (or translucent) material and has a certain geometry of the cross-section, so that it can be pressed in with a certain force by the fingers.
  • This certain resistance is due to toggle lever effects with a certain geometry (in particular from two flanks) or only single-flanked or only single-flanked but two-parted toggle-lever elements (see Figures 2, 4 and 5) so that when they are pushed in, they initially rise slightly, then reach a maximum and then the resistance decreases again, so that the triggering Element the area underneath surface (especially a printed circuit board) safely and noticeably.
  • This input surface which works with toggle lever and buckling effects, is characterized in particular by the fact that it can be produced by extrusion (see Figures 2, 4 and 5). Then you can (a) leave the complex area in itself, (b) cut open this product from the underside so that the surface running through it is preserved or (c) in this product (e.g. by hot profile cutting or LASER Cut) a certain profile from the underside (the surface running through it remains intact) so that the toggle lever supports are separated from each other in the transverse direction, so they hardly influence each other in their impression behavior (see Figure 3). In the case of (c), additional volume is created under the surface in which LEDs can be accommodated. In a further step, certain contact zones on the underside can be produced by printing conductive (and at the same time elastic) material. In the last step, this product can be clicked on a circuit board can be glued on. This circuit board can in particular cross conductors to the

  • This computer input is further characterized by the fact that it can take on additional tasks that make it easier and more intuitive to work, in particular by distinguishing two (or more) fingers simultaneously (apart from working in the sense of a “QWERT keyboard”).
