Virtual Light Source Object Animation for Intuitive Lighting Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of information processing apparatuses with virtual lighting effects struggle to recognize changes in lighting effects without interacting with the light source object, especially if unfamiliar with the apparatus's operation.
Innovation Solution
An information processing apparatus that includes a display unit for captured images, a change unit to modify the virtual light source object based on elapsed time, and an adding unit to apply the changed lighting effect to the image, allowing users to easily recognize changes in lighting effects without explicit user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the lighting effect is changed only through user operation on the light source object, then the user can control the lighting effect, but the user may be unaware of being able to change the lighting effect if unfamiliar with the apparatus
Solution Approach 1:
The system automatically changes the light source object state and lighting effect at predetermined time intervals without requiring user operation. This preliminary action demonstrates the lighting effect change capability to users who may be unfamiliar with the apparatus, while the system remains ready to respond to user operations when needed.
Solution Approach 2:
The lighting effect change function serves itself by automatically demonstrating its capability through periodic state changes of the light source object. The system performs the function without external user intervention, making the capability visible and intuitive to users.
2Ease of operation
If the light source object state changes automatically based on elapsed time, then the user can easily recognize lighting effect changes, but the system requires continuous time tracking and state management
Solution Approach 1:
The system provides visual feedback by changing the light source object state and corresponding lighting effect at regular intervals. This feedback mechanism makes the automatic time-based state management transparent to users, showing them the relationship between time passage and lighting effect changes without exposing the underlying complexity.

AI summary
An information processing apparatus includes a display unit configured to display a captured image and an object representing a state of a virtual light source, a change unit configured to change the object and change the state of the virtual light source based on an elapsed time, and an adding unit configured to add a lighting effect to the captured image, the lighting effect being provided by the virtual light source the state of which has been changed by the change unit.
