Controller Grip Orientation Detection via Attitude Calculation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional information processing systems that determine the mode of holding a controller device based on user input are prone to errors due to incorrect self-reporting by the user.
Innovation Solution
The system includes a controller device with a lopsided grip portion and an attitude calculation unit, which calculates the device's attitude to determine the orientation of the grip portion, allowing for precise determination of the holding mode, and includes a process executing unit that varies information processes based on this determination, along with an output unit that provides images or sounds to guide the user in holding the device correctly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the mode of holding is determined based only on user input, then the system can operate with simple determination logic, but the determination accuracy deteriorates due to erroneous user input
Solution Approach 1:
The controller device automatically determines the holding mode by analyzing its own attitude data from sensors, without requiring user input. The determination unit uses the calculated attitude to identify which hand the user is holding with, making the system self-diagnosing and eliminating reliance on user self-reporting.
Solution Approach 2:
The patent replaces the manual input method (user pressing buttons or speaking) with an automatic sensor-based detection system. The attitude calculation unit processes data from acceleration and angular velocity sensors to determine holding mode, substituting mechanical/user-based determination with automated electronic sensing and processing.
2Measurement precision
If the grip portion is formed lopsided to enable orientation determination, then the holding mode can be precisely determined, but the controller device loses symmetry and may affect manufacturing simplicity
Solution Approach 1:
The grip portion is deliberately designed with lopsided orientation relative to the housing center, creating an asymmetric feature that enables the determination unit to distinguish between different holding orientations. This asymmetric design provides a reference that allows the system to accurately determine whether the user is holding the controller with their left or right hand.
3Ease of operation
If the system provides visual and auditory cues to guide user holding, then the ease of operation improves, but the device complexity increases due to additional output functions
Solution Approach 1:
The determination unit provides visual feedback through a display unit and auditory feedback through a speaker, guiding the user on the correct holding orientation. The system continuously monitors the attitude and provides real-time feedback to help the user adjust their holding姿势, making the operation more intuitive and easier to learn.

AI summary
An example controller device includes a housing, and a grip portion formed lopsided with respect to a center of a predetermined surface of the housing. An information processing system calculates an attitude of the controller device, and determines the orientation of the grip portion with respect to the center based on the attitude of the controller device. For example, the information processing system determines whether the grip portion is facing right or facing left with respect to the center. Thus, the information processing system can precisely determine the mode of use in which the controller device is used.
