Gesture Emulation Remote Control for Multi-Touch Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote control systems for touch screen devices are complex and fail to effectively interpret multi-touch commands, particularly when interactions involve multiple fingers, as they do not directly correspond to the intuitive control methods of touch screens.
Innovation Solution
A user-to-machine interface system using a remote control with motion sensing capabilities that processes gestures around specific axes to emulate touch commands without signal conversion, allowing direct control of touch screen devices from a distance, including single and multi-touch gestures, and accommodating multiple users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a remote control system uses signal conversion to control touch screen devices, then the device can be controlled from a distance, but the control process becomes complex and cannot effectively interpret multi-touch commands
Solution Approach 1:
The patent creates virtual touch points that copy the behavior of actual finger touches on the screen. The remote control system generates synthetic touch events that mimic the position, pressure, and movement of real fingers, allowing multi-touch gestures to be emulated without complex signal conversion. This copying approach simplifies the control architecture while maintaining full multi-touch functionality.
2Device complexity
If a remote control uses a single cursor to control screen functions, then the control mechanism is simplified, but it cannot directly correspond to multi-touch interactions with multiple fingers
Solution Approach 1:
The patent segments the control mechanism into multiple independent virtual touch points, each corresponding to a finger position. Instead of using a single cursor, the system creates N separate touch points that can be positioned and moved independently across the screen. This segmentation allows the remote control to fully support multi-touch gestures while keeping each individual touch point's control mechanism simple and intuitive.
3Ease of operation
If touch commands are controlled directly by remote orientation and movement, then the control becomes more intuitive, but the system cannot accommodate multiple users simultaneously
Solution Approach 1:
The patent implements a universal touch point management system that can serve multiple users simultaneously. Each user's gestures are captured and converted into virtual touch points that are processed through a common interface. The system universally handles touch events from any user, maintaining the intuitive gesture-based control while accommodating multiple users through centralized touch point coordination and user context management.

AI summary
A user to machine interface emulates a touch interface on a screen. The interface is configured for operating in a touch emulation mode based on a triggering event. A triggering event may be a rotation around a first axis of an angle higher than a first threshold. Analysis of the amount of rotation around a second axis may be used to determine the number of fingers defining a specific touch gesture. An infinite variety of touch gestures may therefore be emulated by a remote control based on application context thus allowing for multiple uses of the touch screen machine from a distance.
