Mode Switching for Global Coordinate Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic apparatuses that track human body motion for controlling operations often rely on local coordinate systems, which are not related to the real environment, limiting their applicability in interactions with other objects in the real world.
Innovation Solution
A method and apparatus that switch between host and client modes to provide positioning information in a global coordinate system, using a communication transceiver, processor, and motion sensor to broadcast and receive information, allowing devices to determine their position relative to real objects in the environment through trilateration and image recognition.

Engineering Contradiction Analysis
1Measurement precision
If local coordinate system is used for motion tracking, then device operation control is achieved, but positioning information related to real environment is lost
Solution Approach 1:
The system divides positioning into two independent coordinate systems: local coordinate system for motion tracking and global coordinate system for real environment positioning. Each coordinate system handles specific functions, allowing the device to maintain precise motion control while also achieving real environment positioning through separate but coordinated systems.
Solution Approach 2:
A mode switching mechanism acts as an intermediary between local and global coordinate systems. The switching condition detector and mode switch enable the system to transition between host mode (broadcasting global positioning) and client mode (receiving global positioning), facilitating integration of both coordinate systems without direct conflict.
2Loss of information
If host mode broadcasts global coordinate system information, then positioning information is provided, but device complexity increases
Solution Approach 1:
The system implements dynamic mode switching between host and client modes based on detected switching conditions. This allows the device to adapt its functionality and information broadcasting behavior dynamically, providing global positioning information when needed while reducing operational complexity in other states.
Solution Approach 2:
The mode switching mechanism enables a single device to perform multiple functions: it can operate as a host broadcasting global coordinate information, or as a client receiving such information. This multi-functionality allows the same hardware to serve different positioning roles without requiring separate dedicated devices for each function.

AI summary
A method and an apparatus related to multiple modes are provided. In the method, the first mode is operated. The first mode is a host mode or a client mode, and the host mode is configured for broadcasting information related to a global coordinate system to a device operated with the client mode. A switching condition is detected, and the first mode is switched to the second mode. The second mode is another one of the host mode and the client mode. The second mode is operated. Therefore, the positioning information of a global coordinate system can be provided for motion sensing apparatuses.
