Personal digital assistant

An information processing apparatus that detects a first location of the information processing apparatus; receives information representing a target location from a target information processing apparatus; detects a target direction from the first location toward the target location; detects an orientation of a casing of the information processing apparatus; calculates an angular difference between the target direction and the orientation of the casing; determines a perceptual strength of each of a plurality of active elements disposed in different locations on or within the casing based on the angular difference; and controls each of the plurality of active elements based on the perceptual strengths.
