Mobile Terminal Pointing Control for Indoor Device Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for indoor positioning and control of electronic devices lack efficient methods for legacy device registration and seamless communication protocol changes based on user direction, leading to inconvenient device selection and control.
Innovation Solution
A mobile terminal system that measures its location and direction to select and control electronic devices by pre-registering legacy devices and automatically switching communication protocols based on user input, using a combination of sensors and wireless communication modules to generate maps and control commands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a mobile terminal uses traditional device selection methods requiring manual search and selection from lists, then device control functionality is achieved, but user convenience and operation speed deteriorate
Solution Approach 1:
The patent replaces manual mechanical scrolling and selection operations with an optical pointing system. The mobile terminal uses its camera to capture images of devices, and image recognition algorithms automatically identify and select the pointed device, substituting manual navigation through device lists with intuitive visual pointing.
Solution Approach 2:
The patent introduces an image recognition system as an intermediary between the user's pointing action and device selection. The camera captures the device, the system processes the image to identify the device, and then automatically selects it, mediating the interaction between user intent and device control.
2Adaptability or versatility
If a mobile terminal supports multiple communication protocols for different device types, then device compatibility is improved, but system complexity increases
Solution Approach 1:
The patent implements automatic protocol detection and selection, where the system autonomously identifies the appropriate communication protocol based on the pointed device type and configures the connection without user intervention. This self-service approach eliminates the need for users to manually select or understand different communication protocols.
Solution Approach 2:
The system dynamically changes communication parameters including protocol type, transmission power, and data format based on the identified device characteristics. This adaptive parameter adjustment allows seamless communication with diverse devices without requiring complex manual configuration.
3Adaptability or versatility
If legacy devices without communication functionality are to be controlled, then system universality is improved, but registration and control complexity increases
Solution Approach 1:
The patent replaces complex manual registration procedures with visual pointing and image recognition. Users simply point the camera at the legacy device, and the system automatically extracts device information from the image, identifies the device type, and completes registration without requiring users to navigate complex registration interfaces or understand technical protocols.

AI summary
A method for controlling a mobile terminal, and which includes establishing communication connections, via a communication unit of the mobile terminal, with a plurality of reference devices, for a location-based service to calculate a current location of the mobile terminal; displaying a list of controllable devices on a display unit of the mobile terminal based on the calculated current location of the mobile terminal; receiving, via a controller of the mobile terminal, a selection of a specific device from displayed list of controllable devices; storing location information about the selected device in an internal or external memory of the mobile terminal; and displaying a first graphic image for controlling a first device corresponding to the calculated current location and a direction of the mobile terminal.
