The invention relates to a method and an apparatus for using a wide keyboard including a wide range of keys in small mobile devices. A method relates to operating a mobile device having a touch sensitive display divided in input and output portions. A first location of a tactile input is detected on an input portion of the touch sensitive display displaying a plurality of keys. Next the input portion display view is zoomed by displaying and linearly magnifying the detected tactile input area and...

A computer or a display apparatus with an input function which is of simple construction and has high operability for touch input or pen input. A system body, a cover unit having a display panel with an input function on one side, and connection means such as a rotatable arm, which is rotatably connected to the cover unit and to the system body at a different portion from a portion at which said cover unit is conventionally connected, so as to allow the cover unit to be placed on the system body...

An optical touch panel including a support, an optical light guide illumination assembly arranged along and above at least most of a periphery of the support to define a detection region, the assembly including at least one optical light guide and a light source arranged for directing light along the at least one optical light guide, at least one light detector, arranged to detect changes in the light received from the optical light guide illumination assembly produced by the presence of an obje...

The present invention determines angular position using a potentiometric touch sensor. The sensor has an annular pattern of resistive material on a portion of a bottom substrate top surface. Conductive drive lines and fixed potential conductive traces radially traverse the bottom substrate top surface and are electrically coupled to the resistive material. Conductive sense traces radially traverse the bottom substrate top surface. A conductive layer on a bottom surface of a top substrate is posi...

An upper electrode plate has a 0.15 to 0.8 mm thick optically isotropic heat-resistant transparent resin plate having a glass transition temperature characteristic of not less than 150.degree. C. The heat-resistant transparent resin plate is laminated directly or indirectly on a quarter wave plate all over their surfaces.

A Graphic Input Device comprises a pen-shaped pointing device moving about a writing surface and using ultrasonic (US) waves propagating in the air to measure displacement. Can be used in either a 2D or 3D mode. Uses displacement measuring means for two directions in space, each parallel to the writing surface, and comprising means to establish an US waves path between an US transmitter and an US receiver; means to measure changes in the phase of the received signal, and for computing the displa...

A liquid crystal module comprises a liquid crystal panel including mutually orthogonal row electrodes and column electrodes and a liquid crystal layer sealed between the electrodes as a display element, a row electrode driving circuit driving the row electrodes of the liquid crystal panel, and a column electrode driving circuit driving the column electrodes. A detecting electrode detects scanning signals applied to the row and column electrodes of the liquid crystal panel by electrically couplin...

A coordinates input device includes: a liquid crystal sheet comprising a conductive layer, a transparent high electric resistant layer, a liquid crystal-dispersed polymer layer, and a transparent insulating layer, all of which are sequentially laminated on a board; and a tablet comprising a Y-axis coordinate resistant sheet, a pressure sensitive sheet, an electrode sheet, a pressure sensitive sheet, an X-axis coordinates resistant sheet, and a flexible film for protection, all of which are seque...

A system and method are disclosed for dynamically labeling touch sensitive buttons in a digitizing display. The display is partitioned into a main panel display region and a button panel display region. A touch overlay is also partitioned into a main panel touch region and a main panel display region. A button panel driver program defines button touch areas and button display areas enabling the dynamic labeling and relabeling of the touch sensitive buttons and the simultaneous touching of combin...

Disclosed herein is a portable electronic device including an operation surface for inputting an operating action of a user, detecting means for detecting the coordinates of a point of contact of a user's finger with said operation surface, a memory for storing information representing a deviation between the coordinates of a point on said operation surface where the user desires the user's finger to touch said operation surface and the detected coordinates of the point of contact, and correctin...
