Abstract

An information processing apparatus that includes a first sensor that receives a first type of signal; second and third sensors that receive a second type of signal; a control unit that calculates 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; and a display that displays an image corresponding to a path obtained based on changes in position of the source calculated by the control unit.

Claims

1. 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;

a control unit that calculates 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; and

a display that displays an image corresponding to a path obtained based on changes in position of the source calculated by the control unit.

2. The information processing apparatus of claim 1, wherein the first sensor is an infrared sensor that receives an infrared signal transmitted from the source.

3. The information processing apparatus of claim 1, wherein the second sensor and the third sensor are ultrasonic sensors that receive an ultrasonic signal transmitted from the source.

4. The information processing apparatus of claim 1, wherein the information processing apparatus is a mobile terminal including a housing having top, bottom and side surfaces.

5. The information processing apparatus of claim 4, wherein the first sensor is located substantially in a center of a side surface of the housing.

6. The information processing apparatus of claim 5, wherein the second and third sensors are located on the side surface of the housing on opposite sides of the first sensor and at equal distances from the first sensor.

7. The information processing apparatus of claim 1, wherein the control unit calculates the position based on a difference between the first time and the second or third times, and a difference between the second and third times.

8. The information processing apparatus of claim 1, further comprising:

an acceleration sensor that detects an acceleration externally applied to the information processing apparatus.

9. The information processing apparatus of claim 8, wherein the control unit compares an output of the acceleration sensor to a predetermined threshold value.

10. The information processing apparatus of claim 9, wherein, when the control unit determines that the output of the acceleration sensor exceeds the predetermined threshold value, the control unit performs correction processing to correct a position of the information processing apparatus relative to the source.

11. The information processing apparatus of claim 10, wherein the correction processing includes controlling the display to sequentially display a first mark and a second mark on the image displayed by the display.

12. The information processing apparatus of claim 11, wherein upon displaying the first mark a next position calculated by the control unit is registered as a first position corresponding to the first mark.

13. The information processing apparatus of claim 12, wherein upon displaying the second mark a next position calculated by the control unit is registered as a second position corresponding to the second mark.

14. The information processing apparatus of claim 13, wherein the control unit controls the display to rotate the displayed image based on the first position corresponding to the first mark and the second position corresponding to the second mark.

15. The information processing apparatus of claim 11, wherein the first mark and the second mark are selected from among points on the path in the displayed image and correspond to an evaluation value in a horizontal direction and an evaluation value in a vertical direction.

16. The information processing apparatus of claim 11, wherein the first mark and the second mark are randomly selected points on the path in the displayed image.

17. The information processing apparatus of claim 1, wherein the control unit controls the display to display an image indicating a distance between two points.

18. The information processing apparatus of claim 17, wherein the control unit controls the display to display a measurement value corresponding to a difference between a first calculated position of the source and a second calculated position of the source.

19. A method performed by an information processing apparatus, the method comprising:

receiving a first type of signal transmitted from a source at a first sensor at a first time;

receiving a second type of signal transmitted from a source at a second sensor at a second time;

receiving the second type of signal transmitted from the source at a third sensor at a third time;

calculating a position of the source based on the first time, the second time, and the third time; and

displaying an image corresponding to a path obtained based on changes in position of the source calculated by the control unit.

20. A non-transitory computer-readable medium including computer program instructions, which when executed by an information processing apparatus, causes the information processing apparatus to perform a method, the method comprising:

receiving a first type of signal transmitted from a source at a first sensor at a first time;

receiving a second type of signal transmitted from a source at a second sensor at a second time;

receiving the second type of signal transmitted from the source at a third sensor at a third time;

calculating a position of the source based on the first time, the second time, and the third time; and

displaying an image corresponding to a path obtained based on changes in position of the source calculated by the control unit.
