Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing apparatuses, such as head-mounted displays, face challenges in performing multiple control operations using data from various sensors without changing the operating system, particularly in integrating sensor data for different control states and improving user operability.
Innovation Solution
The apparatus includes an operation unit, a first detection unit for detecting the operation unit's direction, an input and output conversion unit that adjusts inputs based on different regulations depending on the operation unit's state, and a control processing unit that performs operations based on both the converted outputs and the apparatus's state, allowing for varied control operations and improved user interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single gyro sensor is embedded in the operation unit, then the operation can be performed with the angular velocity detected by the gyro sensor, but it is difficult to mount a sensor other than the gyro sensor to perform different operations
Solution Approach 1:
The operation unit is designed to accommodate multiple types of sensors (acceleration sensor, gyro sensor, touch sensor, etc.) and perform diverse control operations based on the detected results from these sensors. The control unit is configured to execute different control operations corresponding to detected results from multiple sensors, enabling a single operation unit to serve multiple functions without requiring separate dedicated units for each sensor type.
Solution Approach 2:
The system dynamically switches between different control operations based on which sensor is active and what detection results are obtained. The control unit adapts its behavior in real-time according to the sensor type and detection output, allowing flexible and versatile control operations from a unified operation unit structure.
2Adaptability or versatility
If multiple sensors are integrated to perform different control operations, then various control operations can be performed, but the device complexity increases
Solution Approach 1:
Multiple sensor types (acceleration sensor, gyro sensor, touch sensor) are merged into a single operation unit structure. The control unit integrates the processing logic for all sensor types into one unified control system, combining multiple sensor functions and control operations into a single integrated unit rather than separate dedicated units.
Solution Approach 2:
The operation unit is designed as a universal platform that can accommodate multiple sensor types and perform diverse control operations. The control unit is configured to execute different control operations corresponding to detected results from multiple sensors, enabling a single operation unit to serve multiple functions.
3Measurement precision
If the operation unit direction is constantly detected to improve control precision, then control precision is improved, but the detection load on the apparatus increases
Solution Approach 1:
Instead of continuous detection, the system performs direction detection periodically or based on specific trigger conditions. The control unit determines the operation unit direction based on detection results from sensors like the acceleration sensor, but the detection can be optimized to occur at appropriate intervals rather than continuously, reducing processing load while maintaining sufficient precision for control operations.

AI summary
An information processing apparatus includes: an operation unit which receives an operation; a first detection unit which detects a direction of the operation unit; an input and output conversion unit which converts an input of the operation received by the operation unit into an output based on a first regulation, when the direction of the operation unit is in a first state, and converts the input into an output based on a second regulation which is different from the first regulation, when the direction of the operation unit is in a second state; a second detection unit which detects an apparatus state which is at least one of a position and a direction of the information processing apparatus; and a control processing unit which performs a control process of the information processing apparatus, based on the output from the input and output conversion unit and the apparatus state.
