Noncontact UI Operation Objects for Gesture Precision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing noncontact-type user interfaces face challenges in performing gesture operations without direct screen contact, making certain operations, such as taps and pinches, difficult to execute effectively.
Innovation Solution
An information processing apparatus equipped with a processor that detects specific noncontact operations and displays operation objects to facilitate gesture operations by analyzing user movement over the operation surface, using sensors to detect object proximity and movement patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a noncontact-type user interface is used, then hygiene and ease of cleaning are improved, but the ease of performing gesture operations deteriorates
Solution Approach 1:
The patent introduces an intermediary mechanism by displaying operation objects that mediate between the user's noncontact gestures and the system's response. These operation objects serve as visual placeholders that guide users on how to perform gestures without direct screen contact, thereby maintaining both hygiene and operational ease.
Solution Approach 2:
The system provides feedback by detecting the user's noncontact gestures and responding by executing operations equivalent to what would have occurred with direct contact gestures. This feedback loop reinforces the user's actions and ensures reliable operation execution while maintaining the noncontact interface.
2Measurement precision
If noncontact operations are implemented, then cleanliness is improved, but the ability to perform precise gesture operations deteriorates
Solution Approach 1:
The patent applies preliminary action by displaying operation objects before the user performs the gesture. These operation objects pre-indicate the expected gesture type and location, allowing users to prepare their movements accordingly. This preliminary visual guidance compensates for the lack of direct tactile feedback in noncontact operations, maintaining precision without sacrificing ease of operation.

AI summary
An information processing apparatus includes a processor configured to: detect a specific noncontact operation performed by a user on an operation surface; and display, if the specific noncontact operation is detected, an operation object for achieving a gesture operation based on movement of the user with respect to the operation surface.
