Definitions

  • the described invention represents a control unit that is used for positioning and control of PC cursors and other virtual and physical objects.
  • the device's control module comprises a button that is mounted on a horizontally moveable guide plate, and the horizontal (X-Y) position can be determined by an opto-electronic sensor that has the capability to detect movement of a pattern on the lower surface of the guide plate.
  • mice The most popular devices used for control of cursors and other graphical symbols and objects on the PC screen are mice, track-balls, touch-pads and TrackPointTM buttons.
  • the track-ball can be compared with an inverted mouse, where the ball is controlled by the thumb.
  • the original track-ball utilised the same signal generating system as the mouse (U.S. Pat. 5,122,654; U.S. Pat. 5,008,528).
  • a modern version of the track-ball includes a rotating ball with a randomly patterned (speckled) surface that is illuminated by diffuse light, whereby a picture of part of the surface is focussed onto a photosensor matrix (U.S. Pat. 5,288,993 and U.S. Pat. 5,703,356).
  • An analyser associated with the sensor matrix detects motions of the ball and transforms this information into conventional control signals.
  • mice and track-balls have disadvantages, particularly regarding precision, ergonomics and scalability.
  • Other systems are based on index finger control or incorporate control sticks that are seized by fingers or hand, providing slightly better precision. They are also better suited for incorporation in mobile devices, e.g. hand-held computers and telephones (U.S. Pat. 4,736,191; U.S. Pat. 4,680,577; PCT/US89/05662 ; EP A3 0,295,368; EP Al 0,640,937; U.S. Pat. 4,719,455; PCT/JP89/01148; PCT/CA90/00022 ; U.S. Pat. 4,935,728; EP A3 0,556,936) .
  • control module comprises a finger-grip or button that is mounted on a horizontally sliding plate (guide plate) .
  • This "stick- and-plate” concept utilises several different signal- generating systems (sensors) .
  • a preferred embodiment employs a concentrated light beam (generated by a diode laser or LED) , which by means of the control module is directed towards an addressable photosensor matrix. The position of the light spot, appearing where the beam hits the sensor matrix determines the horizontal position of the control module. Movements of the button may thus be used to control movement or position of the cursor .
  • the surface pattern utilised by the present invention may consist of spots, lines, geometric figures or other shapes that may be printed, painted, etched, engraved, or consisting of surface irregularities stemming from a template or cast used in the production process, or be due to inherent properties of the surface material.
  • the signal generating system employs an opto-electronic sensor that is capable of detecting X-Y motions of the control module, whereby a photo-sensor matrix, in association with a set of suitable optical members, a signal processor, a memory, and other electronic utilities, captures sequential pictures of the patterned, lower surface of the guide plate which is being illuminated by diffuse light.
  • the processor/analyser associated with the sensor matrix can interpret signals from said matrix and transform them into control signals that may be used to control movements and location of cursor or object on a display or PC screen.
  • the rim of the patterned area has a higher reflectivity than the central part . This implies that when the rim enters the focal area of the sensor matrix, this is immediately detected by a set of photosensor pixels that will receive light of higher average intensity than the remaining pixels. The analyser logic will interpret this as being due to the control module approaching the border of its mobility range, and hence activate certain program functions.
  • Such program functions are particularly useful in connection with the stick-and-plate concept, where movement of the control module is restricted to within a certain delimited area (mobility range) , and functions are needed to prolong motion control of cursor or object when the control module reaches the border of said mobility range.
  • Such functions are e.g.: a) Transition from congruent to vectorial control mode.
  • the vector controlling the movement is based upon the speed and direction of the control module immediately before entering into the fringe zone, this information being recorded by the memory of the sensor or control unit.
  • Cursor leap to display border When the control module enters the fringe zone at a speed above a certain, pre-determined limit, this will immediately move the cursor or object to the accompanying display border.
  • Re-positioning function When the control module enters the fringe zone, a program loop is initiated whereby an analyser circuit connected to the signal processor determines which border or fringe zone segment is involved.
  • the signal processor will interrupt the signal transmission to the object control unit (PC, communication device, etc.), or otherwise give instructions that will terminate any motion of cursor or object, allowing the control module to be retracted from the border without this having any effect on the position of cursor or object.
  • the signal processor will re-establish signal transmission or give instruction that movement of cursor or object is resumed. This program will be running as long as the re-positioning function is active.
  • the activation of functions previously described may be achieved in many different ways, where the use of a segmented pattern is one of several options . Instead of using a rim with higher reflectivity, the same result can, of course be obtained by reducing the reflective properties of the rim. The same result may also be obtained by employing different switch arrangements. By using position-based switch functions whereby different switches are activated depending upon which part or segment of the border is approached by the control module, a switch activation of the described functions can be achieved. Such switch arrangements may be based upon electromechanical or opto-electronic switch concepts .
  • a cursor control unit comprising a button or finger-grip that is mounted on a horizontally sliding plate (guide plate), together constituting the device's "control module” .
  • the button is generally cylindrical with a diameter of 5-20 mm and a height of 2-20 mm.
  • the guide plate has restricted mobility, being limited in its movement to an area of the plane that is equivalent to a square or circle with a diameter of 5-50 mm (the "mobility range") .
  • the shape of the mobility range is preferably square or rectangular (with rounded corners) , or circular.
  • the plate and button is in its "normal position" when placed in the centre of the mobility range.
  • the guide plate is moved by means of the button, e.g. by putting a finger on top of, or seizing it by two fingers .
  • the signal generating system comprises a light source that is mounted under the guide plate, illuminating the lower side of the plate with diffuse light.
  • This side of the guide plate has a pattern that is imprinted, engraved, etched or otherwise applied to the surface, providing patch-like reflections when illuminated by the light source.

  • the analyser circuit/microprosessor is capable of detecting horizontal movements of the control module.

  • the plate pattern may otherwise be segmented, e.g. by using different patterns in the centre and in the peripheral parts, giving rise to differences in reflectivity. Such differences will be detected by the sensor matrix when parts of both segment types are positioned within in the focal area of the sensor matrix.
