Specifically, the main circuit board 12 is disposed inside the housing 11. The control command is a command for moving the cursor. The remote control equipment can be connected with the electronic equipment in a wired or wireless mode, the electronic equipment comprises a host and a display screen, the host is respectively connected with the remote control equipment and the display screen, and the display screen can display a cursor and a window. The remote control equipment is held by a palm of a user, and the host moves a cursor in the display screen according to a control command of the remote control equipment. The operation principle of the user controlling the movement of the cursor in the display screen through the remote control device is well known to those skilled in the art, and will not be described herein again.

Touch sensing elements 1322 are uniformly distributed with sensor elements, and can sense the moving track of conductive module 131 in each area of conductive element 1321 and identify the capacitance corresponding to each area.
The position information of the cursor movement is obtained by converting the physical position information and the electric signal from the position of the conductive module 131 sensed by the touch sensing element 1322 and the capacitance of the conductive area in which the conductive module 131 is located, and then obtaining a displacement coordinate point of the cursor in the next step of the system operation interface.
And (3) a physical conversion relation, namely a cursor displacement coordinate point (X1, Y1) is a touch range and operation range proportionality coefficient (S0) X (key contact sensor coordinate point (X2, Y2)/capacitance (C)).
Thus, the conductive module 131 moves in different conductive areas of the conductive component 1321, and the cursor moves in different distances on the screen under the same distance, and the higher the capacitance corresponding to the conductive area, the smaller the distance the cursor moves on the screen. Therefore, the higher the capacitance corresponding to the conductive area is, the lower the corresponding cursor precision is, and fine movement can be carried out in a small range; the lower the capacitance corresponding to the conductive area, the higher the precision of the corresponding cursor, and the fast movement can be performed in a large range.
In the embodiment of the invention, the conductive components are controlled by the regional capacitance, so that the cursor in each conductive region has different moving precision, the conductive region with high capacitance, the conductive region with low cursor moving precision and low capacitance and the conductive region with high cursor moving precision, and a user can move the conductive module in the corresponding conductive region according to the requirement, thereby meeting the requirements of the user on large-range rapid cursor movement and small-range fine cursor movement.

The cursor moving operation step includes: 1. the user's finger presses and orients the mobile navigation key 134; 2. conductive module 131 under navigation key 134 contacts conductive element 1321 and moves along with the movement of navigation key 134, touch sensing element 1322 senses the movement trace, the conductive area and the capacitance of conductive area of conductive module 131 on conductive element 1321, and outputs the movement trace and capacitance data to corresponding control circuit 1331 according to the conductive area; the control circuit 1331 is used for outputting an electrical signal to the main circuit board 12 according to the moving track and the capacitance data; 4. the main circuit board 12 outputs a control command to the host according to the electric signal; 5. and the host moves and controls the cursor according to the control command.
In the embodiment of the present invention, by setting the navigation key 134, the conductive module 131 is fixedly connected to the navigation key 134, and when the navigation key 134 is acted by a pressing force, the conductive module 131 is contacted to the conductive component 1321, so that the cursor can be moved by pressing and orienting the navigation key on the mobile remote control device with a finger of a user, which is convenient for the user to operate.
In an alternative embodiment, the conductive element 1321 is a conductive ink, and the concentration of the conductive ink is different for each conductive area.
The general physical equations are referenced herein to illustrate the specific circuit signal conversion and control of the various conductive regions of the conductive module 131 in the embodiments of the present invention: concentration of conductive ink versus capacitance.

resistance (R) voltage (U)/current (I),
capacitance (C) is the electric quantity (Q)/voltage (U),
current (I) electric quantity (Q)/time (t),

For the conductive ink with high concentration, after the circuit is conducted, the charge moving speed is high, and the corresponding resistance value is low, so that the capacitance is high. For conductive ink with low concentration, after the circuit is turned on, the charge moving speed is slow, and the corresponding resistance value is high, so that the capacitance is low.

In an alternative embodiment, the conductive strength of the conductive areas decreases from the center of the conductive element 1321 to the outside.
In the embodiment of the invention, the conducting strength of the conducting area is sequentially decreased from the center of the conducting component to the outside, so that the moving precision of the cursor is sequentially increased from the center of the conducting component to the outside, the use habit of a user is met, and the user experience can be improved.
In an alternative embodiment, the navigation assembly module 13 has an exterior housing portion exposed outside the housing 11; the navigation keys 134 cover the outer portion of the housing with a gap from the upper surface of the housing.
Preferably, the navigation keys are circular in shape. In the embodiment of the present invention, by partially exposing the navigation module 13 outside the housing 11, the navigation key 134 covers the components of the navigation module 13 exposed outside the housing 11, and has a gap with the upper surface of the housing 11, so that the navigation key 134 protrudes from the upper surface of the housing 11, which is convenient for a user to press and directionally move the navigation key 134.
