Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rendering systems face challenges in smoothly transitioning between hover and gesture event detection modes, limiting detailed 3D rendering operations and requiring device tilt changes, especially when using finger operations.
Innovation Solution
A three-dimensional position indicator and detection system that allows position indication on a 3D space using a casing with a position indicating part and a tracker, enabling detection by a position detecting sensor, and a spatial position detecting device that calculates positions based on interaction with the tracker and specific positional relations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If switching between hover event detection mode and gesture event detection mode is carried out in a limited spatial region using a motion sensor, then the device can detect gestures, but the operator needs to keep the hover state and change device tilt for switching, limiting detailed 3D rendering operations
Solution Approach 1:
The position indicator is designed to perform multiple functions: it can detect positions in both hover state and contact state, and support both 2D and 3D rendering operations. The device integrates a position detecting sensor that can operate in multiple modes without requiring mode switching, eliminating the need for tilt changes and hover state maintenance.
Solution Approach 2:
The invention extracts the position detection function from the motion sensor-based gesture detection system and implements it through a dedicated position indicating part with position detecting sensor. This separation allows independent optimization of position indication accuracy and gesture operation capability.
2Adaptability or versatility
If position indication is carried out using finger operations on a touch sensor, then the interface can detect gestures, but it is difficult to carry out more detailed indication operation
Solution Approach 1:
The position indicator is divided into a grip part and a position indicating part, where the position indicating part (such as a tip portion) can be precisely positioned on the input surface. This segmentation allows the operator to use the tip for detailed position indication while gripping the handle, achieving both ease of operation and high precision.
3Extent of automation
If switching between hover event detection mode and gesture event detection mode requires device tilt changes, then the motion sensor can distinguish modes, but the operation becomes complex and inefficient
Solution Approach 1:
The position indicating part automatically adapts to different detection modes (hover and contact) without requiring the operator to change device tilt or perform switching operations. The position detecting sensor automatically detects the indicated position based on the physical state, making the system self-adapting and eliminating operational complexity.

AI summary
A position indicator indicates a position in a three-dimensional (3D) space. The position indicator includes an elongated casing; a position indicating part which is disposed at one end of the elongated casing and which, in operation, indicates the position; a grip part configured to be gripped with a palm of a user in a state in which the elongated casing is gripped between fingers of the user; and a tracker which, in operation, causes an external device to detect a tracker position of the tracker in the 3D space, wherein the tracker is disposed so as to be not covered by the user's hand when the user palm-grips the grip part. The tracker position of the tracker and a position of the position indicating part are in a specific positional relation.
