Detailed ways

Please refer to FIG. 1 , which shows an implementation environment diagram and functional module diagram of an embodiment of the handheld device 10 of the present invention. The handheld device 10 is used to control the menu of the multimedia terminal 20 . In this embodiment, the handheld device 10 may be a handheld terminal such as a mobile phone or a tablet computer, and the multimedia terminal 20 may be a terminal that needs to be controlled, such as a set-top box or a smart TV. The multimedia terminal 20 displays on the screen selectable menus, accessible web pages, and playing TV, etc., and the user can control the multimedia terminal 20 to select menus, access web pages, and control TV playback by controlling the shaking and rotating of the handheld device 10. channel, volume, etc.

In this embodiment, the handheld device 10 includes a processor 12 , a memory 14 , a motion sensor 16 , a command generating module 100 and a wireless transmitter 18 . Wherein, the command generating module 100 is a software code stored in the memory 14 and is executed by the processor 12 to realize its functions. In this embodiment, the motion sensor 16 can be a three-axis motion sensor, a gyroscope sensor, a gravity sensor, etc., and can sense the motion of the handheld device 10 .

In this embodiment, the motion sensor 16 detects the motion of the handheld device 10 . The command generation module 100 generates menu control commands for controlling the multimedia terminal 20 according to the detected motion. The wireless transmitter 18 sends menu control commands to the multimedia terminal 20 . After receiving these commands, the multimedia terminal 20 will execute corresponding actions. Here, the user only needs to move the handheld device 10 to complete the functions of the buttons on the common remote control.

In practical applications, there are many kinds of motions of the handheld device 10 , and the following examples illustrate how to control the multimedia terminal through the motion of the handheld device 10 for various motion modes.

First, take the handheld device 10 shaking up, down, left, and right as an example. In this embodiment, the user holds the handheld device 10 and shakes it directionally towards the multimedia terminal 20 . Here, the function to be realized by the handheld device 10 is: the user shakes the handheld device 10 in one direction and then returns to control the menu hotspot of the multimedia terminal 20 to move. For example, shaking the handheld device 10 to the left and then returning to the original place to the right can control the menu hotspot of the multimedia terminal 20 to move.

In this embodiment, the hotspot refers to the currently selected item in the menu, such as the currently played channel, the current volume, the currently selected menu, the currently selected hyperlink, etc. The multimedia terminal 20 replaces the selected item by moving the menu hotspot. project. If the item is linked to another page, the hotspot is triggered to enter the page linked to the item. There are many ways to express the movement of this menu hotspot, such as: select the previous or next menu of the current menu displayed on the display screen of the multimedia terminal 20, turn down the volume or turn it up by one step, and move the channel forward or backward Call one, and so on.

In this embodiment, if the motion sensor 16 first detects that the handheld device 10 moves from the first position to the second position along the first direction, and then detects that the handheld device 10 stays at the second position, and the stay time is less than the preset time. After setting time, it is detected that the handheld device 10 moves from the second position to the first position in the direction opposite to the first direction, thereby indicating that the motion sensor 16 detects the aforementioned shaking of the handheld device 10 . At this time, the command generating module 100 generates a menu control command for moving the hotspot in the menu of the multimedia terminal 20 along the second direction.

In this embodiment, both the first direction and the second direction include up, down, left or right. In fact, the first direction in which the handheld device 10 shakes is not limited, and may be up and down, left and right, diagonally, and so on. The second direction can be determined according to the menu on the display screen. For example, for a menu list with only up and down directions, the left and right shaking of the handheld device 10 may correspond to up and down selection menus. For the menu list with up, down, left, and right directions, the left and right shaking of the handheld device 10 can be corresponding to the left and right selection menus, and the up and down shaking can be corresponding to the up and down selection menus. For controlling the broadcasting of TV programs, shaking the handheld device 10 left and right corresponds to channel selection forward and backward, and shaking up and down corresponds to volume adjustment.

Then, take the handheld device 10 as an example to keep it after moving.
