Context-Aware Application Triggering via Image Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in accurately determining a user's psychological state for personalized content selection, particularly in wearable computer systems with optical transmission type HMDs, where providing suitable services at the right time is difficult due to inaccuracies in assessing the user's situation.
Innovation Solution
An information processing apparatus and method that records event lists associating time information and physical solid image information, uses an image pickup unit to capture real space images, and determines if the images match the recorded information to trigger specific applications, allowing for context-aware service provision and user interface handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If psychological state determination methods are used to select content for users, then personalized service can be provided, but the accuracy of user situation determination is insufficient
Solution Approach 1:
The patent introduces an image pickup unit as an intermediary device to capture the user's actual viewing situation (what they are looking at in their environment). This captured image serves as objective evidence to verify or supplement the psychological state determination, thereby improving the accuracy of user situation assessment while maintaining personalized service capabilities.
2Ease of operation
If wearable computers with HMD are used to provide services, then user experience can be enhanced, but it is difficult to provide services at the right time due to inaccurate user situation assessment
Solution Approach 1:
The patent implements a feedback mechanism where the image pickup unit continuously captures the user's viewing environment and feeds this information back to the control section. The control section compares the captured image with pre-registered event images to determine when specific services should be provided, ensuring services are delivered at the right time based on actual user situation rather than estimated psychological state.
3Measurement precision
If image recognition is used to determine user situation, then service timing can be improved, but the system complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-registering event images and their corresponding service information in the recording unit before actual use. When the image pickup unit captures the user's viewing environment, the control section simply needs to compare the captured image with the pre-registered event images to determine if a service should be triggered. This approach achieves accurate service timing while keeping the real-time processing relatively simple.

AI summary
A recording unit 140 records an event list 152 in which time information and physical solid image information are associated with an event. An image processing portion 234 determines whether an image corresponding to physical solid image information recorded in the recording unit 140 is included in a picked up image picked up within a time zone specified by the time information recorded in the recording unit 140. A condition determination portion 236 determines that an event starting condition is satisfied if it is determined that the image corresponding to the physical solid image information is included in the picked up image. A starting instruction portion 238 instructs an application execution section 220 to execute processing of the application. The application execution section 220 starts processing of the application associated with the event whose starting condition is satisfied.
