An input detection device includes an input processor inputting a drive signal to an electrode group including a number of electrodes that are arranged adjacent to each other among a plurality of electrodes, and a detection processor detecting an input position based on a detection signal corresponding to the drive signal input to the electrode group. The input processor inputs a first drive signal to a first electrode group including electrodes at a first timing and inputs, at a second timing following the first timing, a second drive signal to a second electrode group including a number of the electrodes included in the first electrode group and at least one electrode positioned adjacent to the first electrode group. The detection processor detects the input position based on a first detection signal corresponding to the first drive signal and a second detection signal corresponding to the second drive signal.

A touch input device includes: a position detector that determines an input range in a touch input produced with an inputter on a touch panel and that detects, as a touch position, any position within the input range; a line information generator that generates line information which is information of a line connecting a plurality of the touch positions detected with the position detector; a smoothing level setter that sets, based on the area of the input range, a smoothing level indicating the degree of smoothing; and a smoothing processing processor that executes, on the line of the line information generated by the line information generator, smoothing corresponding to the smoothing level set by the smoothing level setter.

A handwriting input system includes a board for writing and a pen that serves as a writing instrument. The pen includes a pen tip that leaves visible handwriting on the board when the pen tip comes into contact with the board and an identification circuit that provides an identification signal. The board includes a coordinate detection section that detects position coordinates of a position on the board where the pen tip is in contact with the board and a pen identification section that detects the identification signal in a contactless manner.

The document data (e.g., conference materials) are transmitted from a conference server apparatus to a terminal apparatusattending a teleconference, and the terminal apparatusutilizes a displaying unitto display the document data on the lower layer, utilizes a accepting unit(e.g., a pen tablet or a mouse) to accept a writing operation performed on the display screen, generates a write-image regarding the writing operation on a layer upper than the lower layer, and displays and overlays the generated write-image on the document data. At that time, the terminal apparatussets a rectangular write-inhibition area containing character or word included in the sentence of document data. For example, when a leader line is written inside the write-inhibition area, an image regarding the written leader line is displayed outside the write-inhibition area.
