Mobile AR Interface for Precise Air Conditioner Wind Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile terminals lack the capability to effectively control home appliances, such as air conditioners, using augmented reality, limiting user interaction and control over appliance settings like wind direction and force.
Innovation Solution
A mobile terminal equipped with a wireless communication unit, camera, and display unit that outputs state information on air conditioners, allowing users to control wind operation through touch inputs, pinch gestures, and drag movements, enabling remote control of air conditioner settings via augmented reality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a mobile terminal uses traditional control methods for home appliances, then the control functionality is basic and limited, but the user interaction is not intuitive and the control precision is low
Solution Approach 1:
The patent uses augmented reality to create a virtual copy of the air conditioner interface on the mobile terminal display. This virtual interface mirrors the actual appliance controls, allowing users to interact with familiar visual elements. The graphic objects represent real physical controls, enabling intuitive manipulation without requiring users to learn new control paradigms while maintaining precise control through digital interface accuracy
Solution Approach 2:
The system implements real-time feedback by displaying state information about the air conditioner (wind direction, wind force, operational status) directly on the augmented reality interface. As users manipulate graphic objects, the system immediately reflects changes in the virtual interface and transmits control signals to the actual appliance, providing continuous visual confirmation of control actions and appliance responses
2Measurement precision
If a mobile terminal implements augmented reality control with multiple touch gestures, then the control precision and user interaction improve, but the device complexity increases
Solution Approach 1:
The patent implements dynamic control through multiple touch gesture types (pinch-in, pinch-out, drag) that adapt to different control needs. The system dynamically responds to gesture intensity and type to adjust control parameters - for example, pinch gestures control wind force with varying degrees of intensity, while drag gestures control wind direction. This dynamic approach enables precise control without requiring complex hardware modifications, using software-based gesture recognition instead
Solution Approach 2:
The mobile terminal's touch display serves multiple functions: it displays the augmented reality interface, recognizes various touch gestures (tap, pinch, drag), provides visual feedback, and transmits control signals. The same hardware components (display, touch sensor, processor) handle both user interface presentation and control signal generation, eliminating the need for separate specialized controls and reducing overall device complexity while maintaining high control precision
3Loss of information
If a mobile terminal displays state information visually on the display unit, then the user interaction becomes more intuitive, but the loss of information is reduced while maintaining comprehensive control data
Solution Approach 1:
The patent overlays virtual graphic objects and state information directly onto the mobile terminal's display in an augmented reality interface. This adds a visual dimension to the control system, presenting appliance status and control options as graphical elements positioned in spatial context. The state information (wind direction, force, temperature) is displayed as visual indicators alongside interactive graphic objects, making comprehensive information retention intuitive through spatial and visual presentation rather than text-heavy interfaces
