Solution Overview
Problem
Conventional methods lack effective utilization of sensor data, making it difficult to provide appropriate services based on user presence and activity in indoor spaces.
Innovation Solution
An information providing method that uses a processor and memory-based apparatus to collect and analyze sensor data from luminares, audio devices, and sensors to determine user presence and activity, generating information for identifying users or spaces and triggering appropriate services over a network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If sensor data is collected from various sensors placed in indoor spaces, then the quantity of available data increases, but the effectiveness of service provision remains insufficient due to lack of information on how to use the data
Solution Approach 1:
The patent introduces an information processing apparatus that acts as an intermediary between sensor data collection and service provision. This apparatus analyzes sensor data, determines user presence and activity patterns, and generates meaningful information that bridges the gap between raw data and effective service delivery, thereby resolving the contradiction between data quantity and utilization effectiveness
2Adaptability or versatility
If conventional methods are used to process sensor data, then system complexity is minimized, but the ability to provide tailored services based on user presence and activity is insufficient
Solution Approach 1:
The patent segments the service provision system into distinct functional modules: sensor data acquisition, user presence determination, activity pattern analysis, and service generation. This segmentation allows the system to achieve high adaptability and versatility in providing customized services while managing complexity through modular architecture, where each module performs a specific function
3Measurement precision
If sensor data is analyzed to determine user presence and activity patterns, then service provision accuracy improves, but information processing requirements increase
Solution Approach 1:
The patent applies partial action by focusing processing efforts only on relevant sensor data that indicates user presence and specific activities. Rather than continuously processing all sensor data, the system selectively analyzes data that contributes to determining user presence and activity patterns, thereby achieving high measurement precision while reducing overall information processing requirements and energy consumption
Data Source
AI summary
An information providing method that, when (i) presence information indicates that a user is present in a space, (ii) current lighting information indicates that a luminaire is currently emitting light, (iii) the current time is not included in a period indicated in past lighting information, and (iv) operating status information indicates that an audio device is not outputting sound, generates first information indicating that a user is in a space at a time at which the user is not usually in the space, obtains, from a second information processing apparatus connected to a first information processing apparatus, information indicating first request content over a network, and, when content of the first information is included in the first request content, outputs, to the second information processing apparatus, second information including information for identifying a user or space, using the first information.
