Remote Control Interface for Home Automation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing home automation remote controls struggle to seamlessly transition between fine and large-amplitude movements, often compromising ergonomics, as they require multiple turns for large-amplitude changes, and existing dual-touch interface solutions are cumbersome.
Innovation Solution
A remote control interface that detects finger movement amplitude and speed to differentiate between 'long steering' and 'fine control' conditions, adjusting the control amplitude ratio dynamically to facilitate both precise and rapid state changes, allowing direct transition to extreme states when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a fine incrementation step is used for precise actuator displacement, then manufacturing precision is improved, but ease of operation deteriorates when large-amplitude movements are desired
Solution Approach 1:
The remote control dynamically adjusts the amplitude ratio between finger movement and actuator displacement based on detected movement characteristics. When a user performs a large finger movement, the system applies a higher amplitude ratio to achieve large actuator displacement quickly; when small finger movements are detected, a lower ratio is applied for precise control, eliminating the need for multiple knob turns while maintaining precision
Solution Approach 2:
The system changes the control parameter (amplitude ratio) based on the detected speed and amplitude of finger movement. By monitoring movement speed, the system identifies whether the user intends a quick large-amplitude adjustment or a precise small-amplitude adjustment, and adjusts the control sensitivity accordingly to optimize both speed and precision
2Device complexity
If a single touch interface is used for control, then device complexity is reduced, but productivity deteriorates when both fine and large-amplitude movements are required
Solution Approach 1:
A single touch interface serves multiple functions by detecting different movement characteristics (speed and amplitude). The same interface element can trigger either fine adjustments or large-amplitude movements depending on how the user interacts with it, eliminating the need for separate controls while maintaining both precision and speed capabilities
3Productivity
If multiple touch interfaces are provided for rapid and fine movements, then productivity is improved, but device complexity increases
Solution Approach 1:
The patent merges the functionality of multiple specialized interfaces into a single touch interface by detecting movement characteristics. Instead of providing separate controls for rapid and fine movements, the system combines both capabilities in one interface that adapts its response based on the user's interaction speed and amplitude, reducing complexity while maintaining productivity

AI summary
The method involves providing a remote controller with an interface that detects amplitude (102) or speed of displacement of a user's finger. A state of equipment is changed with another amplitude depending on the detected amplitude and amplitude ratio that is higher than a predetermined amplification threshold value when a long piloting condition is met (110). The equipment state is changed with the latter amplitude and performance energy ratio that is lower than or equal to the threshold value when the long piloting condition is not met. Independent claims are also included for the following: (1) a remote control device (2) a home automation installation.
