Detailed ways

Please refer to Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, Fig. 1 is a schematic block diagram of a hand-held electronic device, Fig. 2 is a flowchart of a remote control method, and Fig. 3 is a hand-held electronic device The schematic diagram at the origin position, FIG. 4 is a schematic diagram of the handheld electronic device moving from the origin position to the moving position. The handheld electronic device 1 includes an electronic compass 11 , a processing unit 12 , a display unit 13 and an input unit 14 . The handheld electronic device 1 is such as a mobile phone or a tablet computer, and the display unit 13 and the input unit 14 are integrated into a touch screen, for example. The processing unit 12 is coupled to the electronic compass 11 , the display unit 13 and the input unit 14 . When the user holds the handheld electronic device 1 and enters a certain indoor room, such as bedroom, living room or office, etc., the remote control method can be applied to the handheld electronic device 1, and includes the following steps:

First, as shown in step 21 , the origin direction information Φ1 to Φ3 pointing from the origin position U0 to the controlled devices 31 to 33 is measured via the electronic compass 11 . The reference positions are related to the controlled devices 31 to 33 , and the actual positions of the controlled devices 31 to 33 are used as an example to describe the reference positions in this embodiment. The aforementioned controlled devices 31 to 33 are, for example, home appliances, such as electric fans, televisions or air conditioners, and the origin direction information Φ1 to Φ3 are, for example, angles. For convenience of description, this embodiment takes three controlled devices as an example, but the present invention is not limited thereto, and the number of controlled devices can be adjusted depending on the actual application. In addition, if there is only one controlled device in an indoor room, one reference position can be the actual position of the controlled device, and the other reference position can be a specific position of the indoor room itself, such as a corner or a door, etc. .

Next, as shown in step 22, the moving direction information Φ1' to Φ3' from the moving position U1 to the reference position is measured via the electronic compass 11 . The moving direction information Φ1' to Φ3' are angles, for example. Furthermore, after the user takes a step forward with the handheld electronic device 1 , the position of the handheld electronic device 1 changes from the origin position U0 to the moving position U1 . The processing unit 12 takes the distance between the origin position U0 and the moving position U1 as the unit length of the coordinate system. In other words, the unit length of the coordinate system is the distance that the user takes one step. In this way, the origin position and the moving position respectively correspond to the origin coordinates (0, 0) and coordinates (0, 1) in the coordinate system.

Then, as shown in step 23, the processing unit 23 establishes a coordinate system and calculates the reference position coordinates of the reference position in the coordinate system according to the origin position U0, the moving position U1, the origin direction information Φ1 to Φ3, and the moving direction information Φ1' to Φ3'. It should be noted that as long as the slope of a straight line and any point passing through the straight line are used, the straight line equation of the straight line can be obtained. Furthermore, any two non-parallel lines must intersect at a point. The slope of the straight line can be obtained from the origin direction information and the moving direction information measured by the aforementioned electronic compass 11 , so as to determine the reference position coordinates of the controlled devices 31 to 33 in the coordinate system.

After the system coordinates and the reference position coordinates in the coordinate system are established according to the aforementioned steps 21 to 23, when the subsequent user uses the handheld electronic device 1 to remotely control the controlled device 31, the controlled device 32 or the controlled device 33, hold the The electronic device 1 can determine the controlled device that the user wants to remotely control according to the electronic compass 11, the coordinate system and the coordinates of the reference position.

Then, as shown in step 24, the electronic compass 11 measures the current direction information pointing from the current position to the controlled device to be remotely controlled, and the processing unit 12 controls the display unit 13 to display the controlled device to be remotely controlled according to the coordinate system, reference position coordinates and current direction information. control interface of the control device.

The aforementioned step 24 further includes steps 241 to 245 . As shown in step 241, the display unit 13 displays the indoor layout of the user's environment. Although the indoor layout shown in FIG. 6 is illustrated by taking a rectangle as an example, the present invention is not limited thereto, and the indoor layout may be irregular. Furthermore, the display unit 13 may firstly display a room list as shown in FIG. 5 , the room list includes several options, such as living room or office. After the user selects the room configuration via the input device 14 , the display unit 13 displays the indoor layout of the user's environment as shown in FIG. 6 .

Next, as shown in step 242, the user clicks on the indoor layout and selects the current relative position U' which is probably located in the indoor layout, and the input unit 14 receives the current relative position U' related to the current position in response to the indoor layout. The current relative location U' input by the user may be different from the actual current location U.

Then, as shown in step 243, the processing unit 12 calculates the candidate direction information Φ U' _{, 1} and the candidate direction information Φ _{U', 2} pointing from the current relative position U' to the reference position coordinate P1, the reference position coordinate P2 and the reference position coordinate P3 , and candidate direction information Φ _{U', 3} .

Then, as shown in step 244, the processing unit 120 selects the candidate direction information Φ _U',1 closest to the current direction information Φ _U,1 , and based on the candidate direction information Φ _U',1 closest to the current direction information Φ _U,1 The control display unit 13 displays the control interface of the controlled device to be remotely controlled. For example, the reference position coordinates of the aforementioned controlled devices 31 to 33 in the coordinate system are P1 to P3 respectively. The candidate direction information Φ _{U', 1} is closest to the current direction information Φ _U,1 . The candidate direction information Φ _U′,1 points to the reference position coordinate P1, and the reference position coordinate P1 is the reference position coordinate of the controlled device 31 in the coordinate system. If the controlled device 31 is a TV, the processing unit 14 controls the display unit 13 to display the control interface of the TV as shown in FIG. 7 according to the candidate direction information Φ _U′,1 .
