Vehicle UI Gesture Switching via Proximity Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users, especially in vehicle environments, face difficulty in switching between screen views using swipe gestures due to increased hand-eye coordination requirements, leading to distraction and potential operating errors.
Innovation Solution
A method and user interface that detects user input proximity and displays indications on screen edges for switching between screen views, allowing for swipe or 3D gestures without requiring direct contact, enabling safe and convenient operation by distinguishing between interactions with screen edges and individual tiles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If swipe gestures are used to switch between screen views, then screen view switching is enabled, but hand-eye coordination requirements increase and user distraction occurs
Solution Approach 1:
The patent replaces contact-based mechanical swipe gestures with contactless 3D gestures detected by sensors. Users can switch between screen views by performing gestures in the air (e.g., moving hand horizontally in front of the display) without touching the screen, thereby eliminating the need for precise hand-eye coordination while maintaining functionality.
Solution Approach 2:
The patent introduces visual indicators (e.g., arrows or icons displayed at screen edges) as intermediaries that guide users on how to perform 3D gestures. These indicators appear in response to detecting hand presence near the device, providing intuitive feedback that reduces cognitive load and prevents user distraction.
2Measurement precision
If contact-based swipe gestures are required, then precise control is achieved, but operating difficulty increases especially in vehicle environments
Solution Approach 1:
The patent substitutes contact-based mechanical interaction with contactless gesture recognition using sensors (e.g., cameras, infrared sensors, or capacitive sensors). The system detects hand position and movement in 3D space, enabling precise control without requiring physical contact with the screen, thus improving ease of operation in vehicle environments where users may be wearing gloves or need to minimize contact.
Solution Approach 2:
The patent extends gesture recognition from 2D screen contact to 3D spatial movement. Users can perform gestures in the air with greater freedom of motion, and the system interprets these movements based on multiple spatial dimensions, maintaining precision while significantly improving operational convenience.
3Adaptability or versatility
If multiple interaction methods are supported, then versatility is improved, but system complexity increases
Solution Approach 1:
The patent implements a universal gesture recognition system that handles multiple gesture types (3D swipes, pinches, taps in air) through a single integrated sensor array and processing pipeline. The same hardware infrastructure supports both contactless gestures for screen switching and contact-based gestures for tile manipulation, reducing overall system complexity compared to implementing separate systems for each gesture type.

AI summary
A user interface and a method for changing from a first screen view (I) to a second screen view of a user interface are proposed. The method comprises the steps: – detecting an input means (13) in an approximation region of an input unit, – displaying a message (7a, 7b) at an edge of the first screen view (I) relating to the possibility of changing over to the second screen view, – recognising a predefined gesture of a user, and – changing from the first screen view to the second screen view.
