Abstract: A coordinate input device is provided. The coordinate input device includes a first input device for detecting a position input and obtaining a first input value indicate of the position, a second input device for detecting the position input and obtaining a second input value indicative of the position, the second input value having a tendency to be a more accurate indication of the position than the first input value, a determining unit configured to determine whether the first input device and the second input device simultaneously obtain the first input value and the second input value, respectively, a storing unit configured to store a relationship between the first input value from the first input device and the second input value from the second input device as correction information, and a correcting unit configured to correct the first input value on the basis of the correction information.

Abstract: An input apparatus includes a display element (e.g., an LCD element) and a first sensor. The display element has a display screen of a predetermined size. The first sensor is configured to have a detection area that is smaller than the display screen, and to detect coordinates of a position pointed to in the detection area by a pointing body, such as a finger and a pen. The first sensor is coupled with the display screen such that its detection area, in which a pointing position pointed to by the pointing body is detected, maps to a predetermined display area within the display screen. The input apparatus may further include a second sensor configured to detect a pointing position pointed to by a pointing body in a full display detection area of the display screen, and the input apparatus selectively processes a detection output from the first sensor or the second sensor.

Abstract: A notebook-sized computer, comprising a main unit having a display screen portion with a display screen and a key input portion, said notebook-sized computer further comprising an electrostatic capacitance type input pad by which the touch operation by user's finger is detectable, a palm rest portion arranged near the electrostatic capacitive type input pad underneath which the sensor substrate of a position detection device is placed, and a position detection device comprising the sensor substrate mounted internally in said notebook-sized computer and including a plurality of loop coil groups realized by one or a plurality of patterns on the sensor substrate, each of the loop coils comprising at least one turn, a position detection circuit electrically connected to the loop coils within the sensor substrate, a position indicator having a resonance circuit coupled to said coils in electromagnetic coupling fashion, wherein the detection circuit detects operations initiated by using the position indicator when

Abstract: A position detecting device includes: a display unit having a first electrode formed of a transparent conductive film, a plurality of second electrodes, and display material interposed between the first electrode and the second electrodes; a display driver configured to drive the display unit based on a video signal input to the display driver; and a position detecting section configured to detect a position of an indicator on the first electrode and to output the detected position. The display unit may comprise, for example, an “electronic paper,” such that the display state of the display unit can be maintained even after a drive power applied between the first electrode and the second electrodes is discontinued.
