External Camera Position Detection for Operation Input Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing systems, such as game apparatuses, require an imaging section to detect player actions, which limits interaction processes to only those with an imaging capability, and do not efficiently handle operations without additional imaging provisions.
Innovation Solution
An information processing apparatus with an image acceptance section, an operation signal acceptance section, and a process execution section that can execute processes based on images and signals from operation inputting apparatuses with or without an imaging section, using light emitting sections to identify and position inputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an imaging section is included in the operation inputting apparatus to detect player actions, then the ability to execute interactive processes is improved, but the device complexity and cost increase
Solution Approach 1:
The patent introduces a camera positioned at the display unit as an intermediary to capture images of the operation inputting apparatus. This external camera serves as a mediator between the display unit and the processing unit, enabling position detection without requiring the operation inputting apparatus itself to have imaging capabilities. The camera captures images, and the processing unit determines positions based on these images, resolving the contradiction by centralizing the imaging function externally rather than embedding it in each operation inputting apparatus.
Solution Approach 2:
The patent makes the camera and image processing system universal by using a single camera to capture images of multiple operation inputting apparatuses. The processing unit can identify different apparatuses and determine their positions based on the captured images, allowing the same imaging system to serve multiple functions and multiple devices. This eliminates the need for each operation inputting apparatus to have its own imaging section, reducing overall device complexity while maintaining versatility.
2Measurement precision
If an imaging section is provided in each operation inputting apparatus to enable position detection, then the measurement precision of position is improved, but the manufacturing cost and device complexity increase
Solution Approach 1:
The patent uses an external camera as an intermediary to perform position detection for all operation inputting apparatuses. Instead of each device having its own imaging section, the single camera captures images that are then processed to determine positions of all apparatuses. This approach maintains measurement precision by using the same imaging technology while dramatically simplifying manufacturing, as only one camera is needed instead of multiple imaging sections distributed across different devices.
3Adaptability or versatility
If the operation inputting apparatus includes an imaging section to detect its own position, then the adaptability to various operations is improved, but the device complexity and loss of information increase
Solution Approach 1:
The patent introduces a camera as an intermediary that captures images of the operation inputting apparatus from the display unit side. This external imaging approach allows the system to adapt to various operations by capturing the apparatus from a consistent perspective, eliminating information loss that would occur if each apparatus had to provide its own position data. The camera serves as a neutral intermediary that gathers position information objectively, maintaining information integrity while enabling versatility.
