Projection Control Panel with Multi-Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projection systems face challenges in providing effective human-machine interaction, particularly due to inconvenient hardware key operations, limitations in remote control technology, and a lack of advanced voice and visual interaction capabilities.
Innovation Solution
A human-machine interaction system for a projection system that employs a multi-mode control panel capable of automatic switching between touch mode and full keyboard mode, along with features like automatic charging, anti-slip design, and integration with a multi microphone array and wide-angle lens for voice and visual input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If hanging installation is used to separate the projection device from the screen, then the basic display function is achieved, but the operation of machine-body keys becomes inconvenient
Solution Approach 1:
The patent replaces mechanical key operations with wireless communication technology. The control panel uses Bluetooth or Wi-Fi to communicate with the projection device, eliminating the need for physical machine-body keys on the projector. This allows users to operate the system conveniently from a distance while maintaining basic display functionality.
2Ease of operation
If remote control technology is used for interaction, then portability is improved, but text input, text selection, text editing, and picture clicking functions cannot be supported
Solution Approach 1:
The patent merges the functions of a remote control, keyboard, and mouse into a single control panel. The device includes a touchscreen display that can show a virtual keyboard for text input and selection, while also supporting pointer movement for picture clicking. This unified design maintains portability while providing complete interaction functions.
Solution Approach 2:
The control panel dynamically adapts its interface based on user needs. The touchscreen can display different modes including a virtual keyboard for text input, a pointer for picture interaction, and various application-specific interfaces. This dynamic transformation allows a single portable device to provide diverse interaction functions.
3Reliability
If Bluetooth technology is used for remote control, then connection is established, but only one-to-one binding is achieved which is not a real connection
Solution Approach 1:
The control panel is designed with multi-functionality to work with various projection devices. It supports multiple communication protocols including Bluetooth and Wi-Fi, and can adapt to different device types (projectors, smart TVs, display devices). This universal design enables the control panel to establish reliable connections with multiple different devices rather than being limited to one-to-one binding.
4Adaptability or versatility
If a control panel with full keyboard mode is used, then text input capability is improved, but device complexity increases
Solution Approach 1:
The patent uses a flexible touchscreen display that can show a virtual keyboard when needed. Instead of incorporating a physical full keyboard that would increase device complexity, the system displays a keyboard interface on the touchscreen. This provides complete text input capability while maintaining a simple, thin control panel structure.
Data Source
AI summary
A human-machine interaction system is used with a projector system, and includes an interactive terminal. The interactive terminal has a projection assembly for operating an application system and a control panel for issuing instructions and/or inputting data to the application system according to functional requirements. The human-machine interaction system accomplishes a complex human-machine interaction function by means of multi-mode design for automatic switching between a touch mode and a full keyboard mode of a control panel. In addition, the one-to-one correspondence combination relationship between devices is broken by means of contact detection, so that different control panels can control different intelligent conference projection systems, thereby achieving the free pairing and connection of devices.
