Solution Overview
Problem
Gamers often face difficulties in timely and accurate pressing of hotkeys during urgent situations in games, leading to mistakes or missed actions due to manual operation limitations.
Innovation Solution
An electronic device with a display apparatus and host system that detects external input signals, such as gestures or sound, to trigger virtual macro key inputs, allowing automatic execution of specific keystroke sequences without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If manual operation is used to press hotkeys during games, then the user can control game actions, but the response time is delayed and errors occur during urgent situations
Solution Approach 1:
The system automatically detects gestures or voice commands and triggers corresponding macro keys without requiring manual button pressing. The display apparatus itself serves as the input device by capturing external signals (gestures via image-capturing unit or voice via microphone) and automatically converting them into keyboard scan code sequences, eliminating the need for manual hotkey pressing and ensuring timely, accurate execution of game actions
Solution Approach 2:
The patent replaces manual mechanical button pressing with automated signal recognition and processing. Instead of requiring physical interaction with keyboard buttons, the system uses image-capturing units to detect gestures or microphones to capture voice commands, then automatically processes these signals through video-processing circuits or audio-processing circuits to generate the appropriate keyboard scan code sequences, substituting mechanical operation with automated electronic recognition and conversion
2Productivity
If automated gesture or voice recognition is implemented, then response time is improved and errors are reduced, but device complexity increases
Solution Approach 1:
The display apparatus is designed to perform multiple functions: it serves both as a display device and as an input device for gesture and voice recognition. The image-capturing unit and microphone, along with their respective processing circuits, are integrated into the display apparatus, allowing it to function as a combined display and control system. This multi-functionality reduces the need for separate dedicated input devices and justifies the added complexity by providing comprehensive control capabilities
Solution Approach 2:
The patent combines the display apparatus with gesture recognition and voice recognition functionalities into a single integrated system. The image-capturing unit, video-processing circuit, microphone, and audio-processing circuit are merged with the display controller, creating a unified device that can both display game content and capture/processed input signals. This integration consolidates multiple functions into one device, improving coordination and reducing the overall system complexity despite adding advanced features

AI summary
An electronic device is provided. The electronic device includes: a display apparatus and a host. The display apparatus includes a display controller and a display panel. The host executes an application to render a display image, and transmits the display image to the display controller through an image-transmission channel between the host and the display controller, and the display controller displays the display image on the display panel. The display controller determines whether an external input signal from a user satisfies a predetermined condition. In response to the external input signal satisfying the predetermined condition, the display controller triggers a virtual input signal corresponding to a specific macro key, and transmits the virtual input signal to the host through a data-transmission channel between the host and the display controller, so that the host executes a keystroke sequence corresponding to the specific macro key.
