Abstract

A control method for an electronic device comprising a sensor unit having a first detection range and a second detection range measured from the electronic device, and the second detection range being smaller than the first detection range. The method includes: detecting a 3D movement track of an operation body when the relative distance between the operation body and the electronic device is smaller than the first detection range, the 3D movement track being a continuous movement track having one end between the first and second detection range and the other end equal to or smaller than the second detection range; generating a status change signal when the operation body reaches close to or moves away from the second detection range of the sensor unit; executing a corresponding control command according to the 3D movement track and the status change signal.

First claim

The invention claimed is:

1. A method for moving a display object applied to an electronic device comprising a display unit, wherein a first relationship between the display object and an object display area for displaying the display object in a display area of the display unit is in a first relative position relationship, comprising:
detecting a first operation of an operation body relative to the electronic device;
obtaining a first distance between the operation body and the electronic device according to the first operation;
determining whether the first distance is smaller than or equal to a second detection distance for recognizing a contact operation;
obtaining a first operation parameter and a second operation parameter according to the first operation when it is determined that the first distance is smaller than or equal to the second detection distance, wherein the first operation parameter differs from the second operation parameter;
changing the first relationship between the display object and the object display area from the first relative position relationship into a second relative position relationship based on the first operation parameter and a first moving parameter;
detecting a second operation of the operation body relative to the electronic device after the first relationship between the display object and the object display area is changed from the first relative position relationship into the second relative position relationship;
obtaining a second distance between the operation body and the electronic device according to the second operation;
determining whether the second distance is greater than the second detection distance and smaller than or equal to a first detection distance for recognizing a proximity operation;
obtaining a third operation parameter of the operation body differing from the first operation parameter according to the second operation when it is determined that the second distance is greater than the second detection distance and smaller than or equal to the first detection distance; and
changing a second relationship between the display object and the object display area from the second relative position relationship into a third relative position relationship based on the first operation parameter and a second moving parameter, wherein the second detection distance is smaller than the first detection distance, the third operation parameter includes movement distance of the operation body in the second operation and operation time of the operation body in the second operation,
wherein prior to changing the first relationship, the second operation parameter is transformed to the first moving parameter by applying a first coefficient, and prior to changing the second relationship, the third operation parameter is transformed to the second moving parameter by applying a second coefficient, and the first coefficient is different from the second coefficient, and
wherein the first operation parameter is one of distance, speed, direction, and operation time, the second operation parameter is one of distance, speed, direction, and operation time, the third operation parameter is one of distance, speed, direction, and operation time, the first moving parameter is one of distance, speed, direction, and operation time, and the second moving parameter is one of distance, speed, direction, and operation time.

2. The method as claimed in claim 1 , wherein the obtaining the second distance between the operation body and the electronic device according to the second operation comprises:
obtaining the second distance between the operation body and the electronic device according to the second operation at a predetermined timing.

3. The method as claimed in claim 2 , further comprising:
at a moment when it is determined that the second distance is smaller than or equal to the second detection distance or greater than the first detection distance, maintaining the relative position relationship between the display object and the object display area at the moment unchanged.

4. The method as claimed in claim 1 , wherein when an area of the display object is smaller than that of the object display area, the relationship between the display object and the object display area is in a first relative position relationship refers to: the display object is displayed at a first position of the object display area;
the changing the first relationship between the display object and the object display area from the first relative position relationship into the second relative position relationship comprises: moving the display object from the first position to a second position of the object display area, wherein the second position differs from the first position;
the changing the second relationship between the display object and the object display area from the second relative position relationship into the third relative position relationship comprises: moving the display object from the second position to a third position of the object display area, wherein the third position differs from the second position.

5. The method as claimed in claim 1 , wherein when an area of the display object is larger than that of the object display area, the first relationship between the display object and the object display area is in a first relative position relationship refers to: a first part of the display object is displayed on the object display area;
the changing the first relationship between the display object and the object display area from the first relative position relationship into the second relative position relationship comprises: moving the display object to display a second part of the display object on the object display area, wherein the second part and the first part are at most partially overlapped;
the changing the second relationship between the display object and the object display area from the second relative position relationship into the third relative position relationship comprises: moving the display object to display a third part of the display object on the object display area, wherein the third part and the second part are at most partially overlapped.

6. The method as claimed in claim 1 , wherein the changing the second relationship between the display object and the object display area from the second relative position relationship into the third relative position relationship comprises:
determining movement distance and movement direction of the display object based on the first operation parameter and the second moving parameter;
determining whether the display object after being moved will be in a boundary-exceeding status based on the movement distance; and
when it is determined that the display object after being moved will be in the boundary-exceeding status, moving the display object until the display object is in a boundary status, which is taken as the third relative position relationship between the display object and the object display area;
wherein when an area of the display object is smaller than that of the object display area, the boundary-exceeding status is: a first object boundary corresponding to the movement direction in the display object exceeds the object display area; the boundary status is: the first object boundary coincides with a first display boundary corresponding to the movement direction in the object display area; and
when an area of the display object is greater than or equal to that of the object display area, the boundary-exceeding status is: a second object boundary reversely corresponding to the movement direction in the display object is located in the object display area; the boundary status is: the second object boundary coincides with a second display boundary reversely corresponding to the move
