Description

Technical Field

[0001] This invention relates to the fields of navigation control technology and human-computer interaction technology, specifically to a control method for one-handed blind operation of navigation maps based on a touchpad, trackball, or joystick. Background Technology

[0002] Currently, navigation map operations primarily rely on touchscreens. However, in scenarios such as in-vehicle central control systems, airborne equipment, and non-touchscreen display terminals, touchscreen operation is inconvenient or unusable due to external factors. Especially while driving, users need to lean forward and reach out to touch the screen, resulting in low operating efficiency, poor safety, and seriously affecting driving safety.

[0003] Therefore, there is a need for a navigation map control method that does not rely on touchscreens, can be operated blindly with one hand, and is safer, while also being compatible with a variety of convenient operating devices to meet the usage needs of different scenarios. Summary of the Invention

[0004] Purpose of the invention This invention aims to solve the problems of existing navigation map operations relying on touch screens, inconvenience of blind operation, low security, and limited device compatibility. It provides a navigation map control method based on touchpad, trackball, and joystick, which enables one-handed, blind operation, safe and efficient control of map panning, zooming, view adjustment, reset, and other functions. It is compatible with a variety of operating devices and expands the applicable scenarios.

[0005] Technical solution A navigation map control method based on a touchpad, trackball, and joystick is applied to a navigation electronic device that has a touchpad, trackball, joystick, or expandable connection to the above devices. The touchpad, joystick, and trackball can all be connected to the controlled navigation device through hardware integration, wireless connection, or wired connection. The method includes the following steps: 1. Collect user operation signals on the operating device (touchpad, trackball, or joystick). Touchpad operation signals include single / multi-finger swipe, single click, double click, long press, swipe direction, and swipe distance; trackball operation signals include trackball movement, pressing, and long press; joystick operation signals include joystick flicking, pressing, and long press. 2. Based on preset or customizable mapping relationships, convert the operation signals of the corresponding operating devices into map control commands; 3. Update the map display in real time according to control commands; 4. When the device remains inactive for a preset period of time, it will automatically revert to the default navigation state.

[0006] Furthermore, the control includes: map panning, zooming, rotation, 2D / 3D view switching, positioning reset, view reset, and sensitivity adjustment.

[0007] Furthermore, the control logic based on the touchpad is as follows: a single finger swipe controls map panning; a two-finger swipe controls map zooming; a three-finger swipe controls map view rotation or switching; a single finger double-tap resets the positioning and view; a single finger long press for 5 seconds enters the panning sensitivity adjustment mode, and a two-finger long press for 5 seconds enters the zoom sensitivity adjustment mode. The corresponding sensitivity can be adjusted by swiping, and double-tapping or timeout will exit the sensitivity adjustment mode.

[0008] Furthermore, based on the trackball's control logic: the trackball's rotation signal controls map panning; pressing the trackball once changes its movement to control map zooming; pressing the trackball again restores the map panning control mode; pressing and holding the trackball for 3 seconds enters the map panning sensitivity adjustment mode, where rotating the trackball adjusts the panning sensitivity; pressing and holding the trackball for 5 seconds enters the map zoom sensitivity adjustment mode, where rotating the trackball adjusts the zoom sensitivity; pressing the trackball once or waiting for a timeout exits the sensitivity adjustment mode.

[0009] Furthermore, the control logic based on the joystick is as follows: the joystick's movement signal controls map panning; after pressing the joystick once, the movement changes to control map zooming; pressing the joystick again restores the map panning control mode; pressing and holding the joystick for 3 seconds enters the map panning sensitivity adjustment mode, and moving the joystick adjusts the panning sensitivity; pressing and holding the joystick for 5 seconds enters the map zoom sensitivity adjustment mode, and moving the joystick adjusts the zoom sensitivity; pressing the joystick once or waiting for a timeout exits the sensitivity adjustment mode.

[0010] Furthermore, the mapping relationship between touch / operation actions of each operating device and map functions can be customized in the software.

[0011] Beneficial effects 1. It does not rely on a touchscreen and is compatible with three types of operating devices: touchpad, trackball, and joystick, making it more widely applicable and meeting the usage needs of different scenarios such as in-vehicle, airborne, and non-touchscreen terminals; 2. All three devices support one-handed blind operation, with a simple operation logic that eliminates the need for users to search for the operating area, making operation safer and more efficient; 3. No large physical movements are required, making it especially suitable for driving scenarios, which can effectively reduce the risk of driver distraction and ensure driving safety; 4. The operating device can be adapted to navigation electronic devices through hardware integration, wired or wireless connection, and has strong adaptability; 5. The operation sensitivity is customizable to suit the operating habits of different users and improve the user experience. Figure 1 is a schematic diagram of the overall process of the method of the present invention.
