Projection Region Control via Spatial Sensing and Automatic Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing systems require users to frequently switch to a display control mode and manually position a projection region when changing the projection area, which is inconvenient and inefficient.
Innovation Solution
An information processing apparatus with an input unit for sensing and coordinate information, and a control unit that analyzes the space to automatically set and adjust the projection region based on user input, allowing for intuitive selection and projection at desired positions, even adjusting along edges or avoiding inappropriate surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the user manually switches to display control mode and positions the projection region, then the projection region can be accurately positioned, but the operation becomes complex and time-consuming
Solution Approach 1:
The system automatically detects the projection surface and calculates the optimal projection region using the sensor unit and control unit, eliminating the need for manual user intervention in positioning and setting the projection region
Solution Approach 2:
The manual mechanical operation of switching modes and positioning is replaced by an automatic detection and calculation system using sensor units that capture spatial information and control units that process this data to determine projection parameters
2Measurement precision
If the system requires users to switch to display control mode every time projection region changes are needed, then precise positioning can be achieved, but the time required for operation increases
Solution Approach 1:
The sensor unit continuously captures and stores spatial information about the projection environment in advance, so when projection is needed, the system can immediately retrieve this pre-acquired data and quickly determine the projection region without requiring users to manually search for positioning information
Solution Approach 2:
The system automatically performs the entire process of detecting the projection surface, calculating the optimal region, and setting projection parameters without requiring user intervention, thereby eliminating the time loss associated with manual mode switching and positioning
3Ease of operation
If the projection region is automatically set based on space analysis, then ease of operation improves, but the ability to handle complex spatial variations may be insufficient
Solution Approach 1:
The sensor unit is designed to perform multiple functions including detecting projection surfaces, measuring spatial dimensions, identifying objects in the projection path, and analyzing environmental conditions, enabling the system to adapt to various complex spatial configurations through a single integrated detection system
Solution Approach 2:
The control unit continuously receives spatial information from the sensor unit, analyzes the projection environment, and automatically adjusts projection parameters based on this feedback, enabling the system to adapt to complex spatial variations and make intelligent decisions about optimal projection region placement

AI summary
An information processing apparatus includes an input unit and a control unit. The input unit to which sensing information and coordinate information are input, the sensing information being obtained by sensing a space in which video is projected, the coordinate information being obtained by pointing through a pointing operation of the space by a user. The control unit stores setting information for setting a projection region in a predetermined range in a storage unit on the basis of a result of analyzing a state in the space on the basis of the sensing information and the coordinate information. Then, the control unit controls, in a case where a projection region is designated by the user on the basis of the stored setting information, a projection apparatus to project the video onto the projection region.
