Abstract: An ultrasonic coordinate input apparatus includes: a transmitter that transmits ultrasonic wave; and a receiver that has a function of detecting a position indicated by the transmitter, based on an ultrasonic signal received from the transmitter, while synchronizing with the transmitter. In this ultrasonic coordinate input apparatus, the transmitter is connected to the receiver with a communication line that enables bi-directional communication between the transmitter and the receiver.

Abstract: An input device that transmits, to a host device having a display displaying a pointer, information relating to the pointer and includes a sensor detecting contact information, and further includes an area extracting part and a control part. The area extracting part extracts a contact area of the sensor and a finger based on the contact information detected by the sensor. The control part controls the pointer based on the contact area extracted by the area extracting part.
