Universal Remote Control with Touch Keyboard and Mouse Functions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing universal remote controls are complex to use and inconvenient for controlling multiple devices, especially for text input and Internet-based services, due to the need for separate remote controls for each device and the limitations of virtual keyboards and multi-axis sensors.
Innovation Solution
A universal remote control with a touchpad, display unit, keyboard unit, central processing unit, infrared unit, and Bluetooth unit that enables touch keyboard and touch mouse functions, allowing intuitive selection and control of devices without the need for multiple remote controls or built-in trackballs, using coordinate data to generate and transmit mouse cursor data wirelessly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a universal remote control is used to control multiple electronic devices, then the number of remote controls is reduced, but the operation becomes complicated
Solution Approach 1:
The remote control is segmented into distinct functional units: a touchpad unit for mouse-like cursor control, a keyboard unit for text input, and a display unit for visual feedback. This segmentation allows each unit to specialize in specific tasks, making the overall operation more intuitive despite the device's versatility.
Solution Approach 2:
The patent introduces an intermediary processing system that translates touchpad coordinates into cursor positions and keyboard inputs into device commands. This intermediary layer abstracts the complexity of controlling multiple device types, presenting a unified and simple interface to the user regardless of the target device.
2Ease of operation
If a trackball or multi-axis sensor is used for position selection, then device control is enabled, but the design cost increases and operation becomes inconvenient
Solution Approach 1:
The patent replaces mechanical position selection mechanisms (trackball, multi-axis sensor) with a touchpad that uses coordinate calculation based on touch position. This substitution eliminates complex mechanical components while providing equivalent or superior position selection functionality through software-based coordinate processing.
Solution Approach 2:
The touchpad creates a virtual copy of a computer mouse interface on the remote control. By calculating cursor coordinates based on touchpad finger position, the system replicates familiar mouse-like interaction patterns, making position selection intuitive without requiring expensive specialized hardware.
3Productivity
If a virtual keyboard is used for text input, then text input is enabled, but the implementation becomes inconvenient and time-consuming
Solution Approach 1:
The patent merges the touchpad and keyboard units into an integrated input system. The touchpad handles cursor movement and position selection, while the keyboard unit handles character input. This merging allows text input to be performed through a unified, intuitive interface that combines the advantages of both touch and keyboard interaction, significantly improving text input efficiency.
