Context-Aware IoT Control Using Modality Score Maps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing IoT systems struggle to effectively control multiple electronic devices within a space, leading to suboptimal user experiences due to independent device control without considering overall interaction and context.
Innovation Solution
A computing device determines user context, selects relevant modalities, generates score maps for input and output areas, and calculates scores to optimize device operations for enhanced user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If an IoT server controls each electronic device independently based on device status and function, then device control is simplified and device complexity is reduced, but user experience quality deteriorates and devices do not interact smoothly
Solution Approach 1:
The patent introduces a context information management system that acts as an intermediary between devices and the IoT server. This system collects, manages, and provides context information about user activities and environments, enabling the server to make coordinated control decisions that improve user experience while maintaining manageable system complexity through modular architecture.
Solution Approach 2:
The patent creates a universal context information framework that serves multiple functions: it provides context for coordinated device control, enables user activity recognition, supports personalized services, and facilitates device interactions. This multi-functional approach improves user experience quality without proportionally increasing system complexity.
2Speed
If an IoT server controls multiple electronic devices without considering overall situation, then control processing is faster and response time is reduced, but device interaction smoothness deteriorates and quality of user experience worsens
Solution Approach 1:
The patent implements preliminary action by pre-collecting and managing context information about user activities, environments, and device states before control decisions are needed. This pre-processing of context data enables faster response times during actual control operations while ensuring coordinated and smooth device interactions through advance context awareness.
Solution Approach 2:
The patent establishes feedback mechanisms where context information from device operations and user activities is continuously collected and used to adjust control decisions. This feedback loop ensures that fast control responses remain coordinated and smooth by adapting to changing contexts in real-time.

AI summary
A method performed by a computing device of controlling a plurality of electronic devices according to context of a user is provided. The method includes the computing device determining the context of the user, based on the determined context, selecting at least one modality to be considered when controlling the plurality of electronic devices, obtaining, for each selected modality, a score map indicating an area affected by input and output of the plurality of electronic devices, calculating a score for each selected modality by using the obtained score map, and controlling operations of the plurality of electronic devices based on the calculated score such that the score includes a value indicating a degree of optimization of user experience in the determined context.
