Definitions

  • the present invention relates to a portable device which visualises the keyboard operations made on the back surface or side surface of the terminal, or which is partly or completely invisible from the front of the terminal, on a display at the front surface of the terminal.
  • the display shows a representation of the keys of the keyboard and the user's fingers, the fingers' position relative to the keys, and whether the keys are activated or not.
  • Handheld terminals generally present a compromise between size and functionality. In the pocket the terminal should take almost no place at all. When in use, the terminal should be easy to access with the hands /fingers.
  • An alternative situation is when the terminal is gripped by a user in one hand and the user operates the keyboard with the other hand.
  • the keys of the keyboard are small and difficult to operate, due to the fact that they are closely spaced and the user's fingertips are broad or the user has enough finger motor activity. The operating efficiency would thus be increased if the keyboard could be operated with both hands.
  • Still another alternative situation is when a user operates a portable terminal having the keyboard keys arranged on the side surface of the terminal, such that the keys are partly or fully invisible from the front of the terminal. In that case, the terminal would normally be resting in one of the user's hands and the user would then operate the terminal by pressing the keyboard keys by using one or both hands.
  • CN- 1356622, US-6297752, US-5515305 and KR-20020004420 discloses different devices that all have a keyboard arranged on the back surface. None of said documents include means for indicating, on a display provided at the front side, the position of the user's fingers on the keyboard.
  • DE- 10260499 discloses a keyboard for portable devices.
  • the keyboard is arranged on the back surface of the device, and is transparent so that the user can see where the fingers are.
  • One disclosed embodiment comprises a card on the front surface showing the positions of the keys. This in combination with transparency of the terminal makes it possible to see, through the terminal, where the fingers are positioned on the keyboard.
  • the problem of the prior art devices is that they do not provide enough information about the positions of the fingers relative to the keys of the keyboard, such that a user may enjoy a much improved operational speed.
  • the features of a transparent terminal casing and a position-indicating card as disclosed in DE- 10260499 do not provide the user with the type of information that is required for him to operate the keyboard at significantly higher speeds. This is prevented by the fact that he cannot clearly see the position of the fingers through the position card, the front surface of the terminal casing, circuits and the back surface of the casing/ keys of the keyboard.
  • the user is forced to look down at the keys and can therefore not follow the result of his operations in the application window. It will also be very difficult to see whether a key is activated or not.
  • the prior art fails to disclose any means of giving the user a direct feedback of the finger positions relative to the keys of the keyboard and the keyboard operations.
  • the present invention provides a novel and efficient way of giving the user such information.
  • the present invention achieves such feedback by the terminal design defined in claim 1.
  • the present invention relates to a portable device, which visualises the keyboard operations made on a keyboard arranged on the back surface or side surface of a terminal, on a display on the front surface of the terminal.
  • the display shows a representation of the keys of the keyboard and the user's fingers, and the current position of the fingers relative to the keys of the keyboard, and whether keys are activated or not.
  • the means for transferring information of the positions of the fingers to the display of the said finger movements may be embodied in many different ways. These are defined by the dependent claims. At present, no prior art discloses a terminal design that achieves said visualisation.
  • the main advantage of the device according to the present invention in addition to good ergonomics, is the provision of quicker and more efficient feedback of the user's keyboard operations.
  • the terminal design according to the present invention is particularly suitable for portable devices, such as cell phones, palm tops, portable computers, PDA:s (personal digital assistants), handheld terminals of joystick- type, such as game pads, or manoeuvring or control units for equipment (cranes, robots or different tools), whether they are cordless or not.
