Definitions

  • a touch sensitive operation interface A touch sensitive operation interface
  • the present invention relates to solutions with a touch-sensitive operation interface.
  • the present invention relates to a novel and improved method, system, computer program, physical object and processing device for determining a point of application of force on a surface.
  • Various kinds of devices comprise a user interface that is touch-sensitive. Touch sensitive panels and screens allow a user to interact with the device by touching e.g. pictures, words, symbols or buttons on a touch sensitive surface. Touch sensitive technology can be used as an alternative user interface with applications that normally use electromechanical keyboards or buttons. Some computer applications are designed specifically for touch sensitive technology, often having larger icons and links than a typical, e.g. PC application.
  • a resistive touch screen panel is coated with a thin metallic electrically conductive and resistive layer that causes a change in the electrical current which is registered as a touch event and sent to the controller for processing.
  • Surface wave technology uses ultrasonic waves that pass over the touch screen panel. When the panel is touched, a portion of the wave is absorbed. This change in the ultrasonic waves registers the position of the touch event and sends this information to the controller for processing.
  • Capacitive touch screen panel A capacitive touch screen panel is coated with a material that stores electrical charges. When the panel is touched, a small amount of charge is drawn to the point of contact. Circuits located at each corner of the panel measure the charge and send the information to the controller for processing. Capacitive touch screen panels must be touched with a finger or another object that can distort electrostatic field of the touch screen measurable as a change in capacitance unlike resistive and surface wave panels that can use fingers or stylus without any need for change in capacitance. Capacitive touch screen uses a lot of current to provide the touch detection which is a constraint on screen size and potential interference issues that require careful design to overcome, making large capacitive screen solutions expensive. Also gloves and high humidity prevent them from working.
  • PDA Personal Digital Assistants
  • Most PDAs include only a few mechanical buttons in order to provide as large display area as possible. Therefore, the display area is also used as an input device.
  • the display area is usually touch-sensitive so that information can be transferred into the device just by touching the display or using a special tool, e.g. a special pen (i.e. stylus).
  • a touch screen may also be a touch-sensitive panel.
  • U.S. Pat. No. 5,241,308 (Paragon Systems) describes a touch-sensitive panel for generating selected ones of any of a plurality of different signals, each of which is generated by touching a different location on the panel.
  • the apparatus includes also force-sensing means for sensing the magnitudes of the forces that are applied to each panel member support by the panel member when the member is touched at a selected location.
  • US 2010/0103640 Al describes an integrated feature for frictionless movement of force sensitive touch screen.
  • a complicated suspension mechanism defined by a length of flexible line looped about both said floating touch panel and opposed fixed base panel. This solution is complex and difficult to manufacture.
  • a hand-held device has a display that is covered by a lens (touch sensitive panel).
  • One or more force sensors are attached to the lens in order to determine the point of application on the lens.
  • Each of the force sensors produces a signal in response to a touch on the lens.
  • the signals are received and processed with a processing unit.
  • the movement When the device is kept e.g. in hand and the hand moves, the movement itself produces signals that are not a result of a touch on the lens. If the lens is touched at the same time as the hand moves, the signals comprise two separate signal components: a signal component produced by the touch and a signal component produced by the hand movement.
  • the signal component produced by the movement is an interference signal that distorts the actual touch signal component. Due to the distortion, the actual point of touch may be determined erroneously.
  • support extensions receiving the external force via the force transducers are formed triangular or in tapering form in order to distribute the force sensed by the sensor evenly and keeping the momentum of the force equal along the support extension.
  • at least the main elements of the invention like the touch panel unit are manufactured from planar plates.
  • the present invention has several advantages over the prior-art solutions. Thanks to the force biased operation, the force sensors are effectively protected from excessive forces. On the other hand the traverse, flexible support effectively protects the sensors and makes the force measurement more accurate.
  • Planar structures enable simple and cost-effective manufacturing.

  • one M2F element with 4 force sensors may be be produced from one planar sheet for tablet device (mobile phone, tablet device, palm device) or for control interface (control panel for a welding machine).
  • two M2F elements are allowed to rotate in relation to each other around x or y- axis, whereby the information of the rotation is used as control information in palm devices.
  • the support enabling the rotation keeps the distance between M2F elements unchanged.
  • M2F elements with 1 or 2 force sensors may be produces a palm device, which can be rolled into a roll to be put into pocket or around wrist or into a bag, whereby a xy- translation on nano level may be allowed between two M2F elements (Watch, controller, wrist computer).
  • M2F elements Watch, controller, wrist computer
  • an additional support may be assembled between M2F structures, which essentially prevents the xy-translation between the M2F elements.
  • cursor is controlled in x and y directions by forces measured in M2F elements. For example when pressed right hand side M2F element the cursor moves on the display from right to left and correspondingly to left when the left hand side M2F element is pressed. When pressed M2F element low the cursor moves down and correspondingly when M2F is pressed high the cursor moves high.
  • Mainly planar in this application means in this application elements, which might have, e.g. bended sides, but at least most of the element surface (70-95%) is planar.
  • planar parts of the elements can be achieved easy fixed attachment.
  • an element in this application is meant e.g. an uniform thin layer in the total structure.
  • the touch panel may be equipped with tacktile feedback function enablimg more precise control of the interface in accordance with the invention.

Abstract

L'invention concerne une interface de commande tactile comprenant une unité d'écran tactile (1150) comprenant en outre un écran tactile (1002), une unité de support (1151) supportant l'unité d'écran tactile (1150), et au moins un capteur de force (1104) conçu pour mesurer une force F dirigée sur l'écran tactile (1002). Conformément à l'invention, l'unité d'écran tactile (1150) est formée de trois éléments essentiellement plans (802, 801, 800 ou 302, 301, 300) reliés de manière fixe les uns aux autres.
