Method and device for controlling movement of external device

Abstract

A method and device for controlling movement of an external device. The method (200) comprises: generating an array pattern on an interface of a device (202); and generating a predetermined trace on the array pattern, so that the external device moves according to the predetermined trace (204). By generating a predetermined trace by using an array pattern, the movement of an external device can be controlled rapidly and efficiently.

 a controller;   a memory in communication with the controller, the memory storing executable instructions executable by the controller to:
 generate an array pattern on an interface of the device; 
 generate a predetermined trace on the array pattern so that the external device moves according to the predetermined trace; and 
 control a movement of the external device in accordance with the predetermined trace. 
   
     
     
         2 . The device according to  claim 1 , wherein the executable instructions are further executable by the controller to:
 generate the array pattern on an electronic map of the device.   
     
     
         3 . The device according to  claim 2 , wherein the executable instructions are further executable by the controller to:
 move and/or scale the electronic map and/or the array pattern to generate the predetermined trace on the array pattern.   
     
     
         4 . The device according to  claim 3 , wherein the executable instructions are further executable by the controller to:
 move and/or scale the electronic map and/or the array pattern according to the predetermined trace so that the predetermined trace is completely included in the array pattern.   
     
     
         5 . The device according to  claim 2 , wherein the executable instructions are further executable by the controller to:
 rotate the electronic map and/or the array pattern to generate the predetermined trace on the array pattern.   
     
     
         6 . The device according to  claim 5 , wherein the executable instructions are further executable by the controller to:
 rotate the electronic map and/or the array pattern according to the predetermined trace so that a direction of the predetermined trace matches a direction of the array pattern.   
     
     
         7 . The device according to  claim 1 , wherein the executable instructions are further executable by the controller to:
 automatically translate an endpoint of the trace which is not in the array pattern to a neighboring array point.   
     
     
         8 . The device according to  claim 1 , wherein the executable instructions are further executable by the controller to:
 calculate coordinates of the predetermined trace based on positions of array points associated with the predetermined trace.   
     
     
         9 . The device according to  claim 8 , wherein the coordinates are relative coordinates or absolute coordinates. 
     
     
         10 . The device according to  claim 9 , wherein the executable instructions are further executable by the controller to:
 in response to the coordinates being the relative coordinates, calculate a relative coordinate of a starting array point associated with the predetermined trace on a basis of a center of the array pattern as a coordinate origin;   control the external device to move to the relative coordinate to start to execute the predetermined trace.   
     
     
         11 . The device according to  claim 9 , wherein the executable instructions are further executable by the controller to:
 in response to the coordinates being the absolute coordinates, calculate an absolute coordinate of a starting array point associated with the predetermined trace;   control the external device to move to the absolute coordinate to start to execute the predetermined trace.   
     
     
         12 . The device according to  claim 10 , wherein the starting to execute the predetermined trace comprises:
 starting to execute the predetermined trace from any point of the predetermined trace.   
     
     
         13 . A non-transitory computer-readable medium storing computer-readable instructions that, when executed by a device, cause the device to perform:
 generating an array pattern on an interface of the device; and   generating a predetermined trace on the array pattern so that an external device moves according to the predetermined trace.   
     
     
         14 . The non-transitory computer-readable medium according to  claim 13 , wherein computer-readable instructions cause the device to further perform:
 generating the array pattern on an electronic map of the device.   
     
     
         15 . The non-transitory computer-readable medium according to  claim 14 , wherein the generating a predetermined trace on the array pattern comprises:
 moving and/or scaling the electronic map and/or the array pattern to generate the predetermined trace on the array pattern.   
     
     
         16 . The non-transitory computer-readable medium according to  claim 15 , wherein the moving and/or scaling the electronic map and/or the array pattern to generate the predetermined trace on the array pattern comprises:
 moving and/or scaling the electronic map and/or the array pattern according to the predetermined trace so that the predetermined trace is completely included in the array pattern.   
     
     
         17 . The non-transitory computer-readable medium according to  claim 14 , wherein the generating a predetermined trace on the array pattern comprises:
 rotating the electronic map and/or the array pattern to generate the predetermined trace on the array pattern.   
     
     
         18 . The non-transitory computer-readable medium according to  claim 17 , wherein the rotating the electronic map and/or the array pattern to generate the predetermined trace on the array pattern comprises:
