Attitude Sensor Input Device for Intuitive Item Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for selecting items from a circular ring on a screen require rotation and are not intuitive, making it difficult to operate the desired item effectively.
Innovation Solution
An information processing system that uses an attitude/motion sensor to detect the input device's attitude and motion, allowing for intuitive selection of items by correlating the device's attitude with corresponding items on the screen, with features like projection vector calculation and reference attitude setting for enhanced selection and cancellation processes.

1Ease of operation
If items are arranged in a circular ring shape and selected by rotation according to operation button inputs, then item selection functionality is achieved, but the operation becomes non-intuitive and complex
Solution Approach 1:
The patent replaces the mechanical button-rotation system with an attitude sensor-based selection system. Instead of requiring users to press buttons to rotate items in a circular ring, the system detects the three-dimensional attitude (orientation and position) of the input device in space and directly maps it to select corresponding items displayed on the screen. This substitution of mechanical interaction with spatial attitude detection simplifies the operation and makes it more intuitive.
Solution Approach 2:
The patent transitions from two-dimensional circular ring rotation to three-dimensional spatial attitude detection. Items are no longer selected by rotating within a flat circular interface but by orienting the input device in three-dimensional space. The attitude sensor detects pitch, roll, and yaw angles, allowing users to select items by pointing the device in the desired direction, thereby adding a spatial dimension to the selection process.
2Productivity
If conventional button-based rotation is used for item selection, then selection functionality is provided, but selection speed and efficiency are reduced
Solution Approach 1:
The system performs preliminary mapping between spatial attitudes and item positions. The attitude sensor continuously tracks the input device's orientation, and the system pre-calculates which item corresponds to each possible attitude. This allows for immediate selection when the user points the device at the desired item, eliminating the need for incremental rotation and reducing selection time.
Solution Approach 2:
The patent creates a spatial copy of the item arrangement on the screen that corresponds to the three-dimensional space around the input device. Items are displayed and selectable based on their spatial relationship to the device's attitude, allowing users to select items by pointing in the direction they would naturally indicate, thereby speeding up the selection process.

AI summary
Correspondence data representing correspondence between a plurality of selection target objects and the attitude of an input device is stored in an information processing apparatus. In accordance with attitude/motion data acquired from the input device, the attitude of the input device is calculated. In accordance with the correspondence data, a selection target object corresponding to the attitude of the input device is selected thereby to perform a process based on the selection target object having been selected.
