A mobile device utilizing on-board sensors capturing a rotation vector, the GPS position and an accelerometer is used as a pointing device. Pointing a mobile device in the direction of an object and tilt the device to signify distance, objects can be selected by establishing the GPS coordinates of the object. Tilt of the phone relative to any maximum range defined, will proportionally define the intended range by the tilt angle as proportional representation in distance. Compass direction is supplemented by the tilt angle to calculate the true direction (A compass works when it is level with the ground, the tilt causes significant deviation). With the direction and distance and utilizing the GPS position reading in the mobile device, a second GPS coordinate can be calculated. This GPS coordinate is then matched to objects located in that location. The details of the object selected are displayed on the mobile device. |
