Abstract
The present invention relates to a mobile terminal for detecting an obstacle in the front, comprising: a display unit; a laser sensor for detecting an obstacle located on a moving route by irradiating a laser beam; and a control unit for controlling so as to activate the laser sensor when a predetermined event is detected, measure the distance to an obstacle detected through the activated laser sensor, and display obstacle notification information on the display unit when the measured distance is within a threshold distance.
Claims20
A mobile terminal comprising:
- a display unit;
- a laser sensor configured to emit laser beams to sense an obstacle located on a movement path;
- and
- a controller configured to activate the laser sensor upon detecting a predetermined event, to measure a distance from the obstacle sensed through the activated laser sensor and to control the display unit to display obstacle notification information when the measured distance is within a threshold distance.
A method of controlling a mobile terminal, the method comprising:
- activating at least one laser sensor provided at a rear surface of a body of the terminal upon detecting a predetermined event;
- sensing an obstacle located on a movement path using the activated laser sensor;
- and
- measuring a distance from the sensed obstacle and displaying obstacle notification information on a display unit when the measured distance is within a threshold distance.
