  • Pointer tool
    Patent number: 8005275
    Abstract: This invention relates to a pointer tool for connecting to a display device, comprising a number of sensors elements being positioned on a two dimensional surface, for measuring a predetermined parameter at a surface, the measured quantity being sampled at a chosen rate, and calculating means for comparing the measurements from the sensor elements for detection of movements in two dimensions over the elements based on changes in the measured parameter, the time between the changes and the known relative positions between the sensor elements.
    Type: Grant
    Filed: November 28, 2007
    Date of Patent: August 23, 2011
    Assignee: IDEX ASA
    Inventors: Stig Mathiassen, Svein Mathiassen, Jon Nysaether

  • Pointer tool
    Patent number: 7308121
    Abstract: This invention relates to a pointer tool for connecting to a display device, comprising a number of sensors elements being positioned on a two-dimensional surface, for measuring a predetermined parameter at a surface, the measured quantity being sampled at a chosen rate, and calculating means for comparing the measurements from the sensor elements for detection of movements in two dimension over the elements based on changes in the measured parameter, the time between the changes and the known relative positions between the sensor elements.

  • Navigation tool
    Patent number: 7129926
    Abstract: This invention relates to a navigation tool for connecting to a display device, comprising at least two sensor elements having known positions relative to each other, each sensor element being coupled to detector means for recording a change in a predetermined parametre and timing means for determining the time of change at each sensor element and calculating means for calculating the direction and speed of the recorded changes based on the relative positions of the sensor elements and the duration between the recorded changes.
