Patent ID: 8907931

Claim:
An information processing apparatus comprising: a first sensor that receives a first type of signal; a second sensor that receives a second type of signal; a third sensor that receives the second type of signal; an acceleration sensor that detects an acceleration externally applied to the information processing apparatus; and circuitry configured to calculate a position of a source from which a signal of the first type and a signal of the second type are transmitted based on a first time at which the signal of the first type is received at the first sensor, a second time at which the signal of the second type is received at the second sensor and a third time at which the signal of the second type is received at the third sensor; control a display to display an image corresponding to a path obtained based on changes in position of the source; and perform correction processing to correct a position of the information processing apparatus relative to the source by controlling the display to sequentially display a first mark and a second mark on the image displayed by the display when it is determined that an output of the acceleration sensor exceeds a predetermined threshold value.
