Remote Mobile Device Operation via External Touchscreen Accessory
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices with small screens are inconvenient for extended use or viewing detailed information, as they lack sufficient input and output functionality and a larger display for tasks like GPS navigation and web-browsing.
Innovation Solution
A method and system for remote operation of mobile devices using an accessory with a touchscreen display, communication interface, and controller, allowing users to establish a communication channel, present information, receive input, process it, and initiate actions on the mobile device, enabling enhanced functionality through an external display and input interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the mobile device screen is made smaller for portability, then the portability is improved, but the convenience for extended use and viewing details deteriorates
Solution Approach 1:
The patent introduces a spatial dimension by connecting the mobile device to an external accessory device via wireless or wired communication. This creates a distributed display system where the interface extends from the handheld device to a separate stationary or portable accessory, effectively adding a new spatial dimension for interaction without increasing the size of the mobile device itself.
Solution Approach 2:
The accessory device serves as an intermediary between the user and the mobile device. It receives control signals from the mobile device, processes user input, and presents information on its own display, acting as a mediator that extends the functional capabilities of the mobile device without requiring the mobile device itself to be larger.
2Weight of moving object
If the mobile device screen is made smaller for portability, then the portability is improved, but the input and output functionality deteriorates
Solution Approach 1:
The accessory device is designed with universal functionality, incorporating both display output capabilities and input mechanisms (such as keyboard, trackpad, or touchscreen). This multi-functional accessory can handle various input methods and present diverse information types, making the combined system adaptable to different tasks while keeping the mobile device compact.
Solution Approach 2:
By offloading input and output functions to an external accessory, the system gains enhanced adaptability in a different spatial dimension. The accessory can provide full-sized keyboard, large trackpad, or extended touchscreen capabilities that would be impractical to integrate into a compact mobile device, thereby improving versatility without compromising portability.
3Weight of moving object
If the mobile device is made smaller for portability, then the portability is improved, but the ability to view minute details deteriorates
Solution Approach 1:
The accessory device acts as an intermediary display that can present detailed information at a larger physical size. While the mobile device remains compact for portability, the accessory provides a larger screen real estate that enables users to view minute details such as text, maps, or data with greater clarity and precision.
Solution Approach 2:
The system transitions from a single small display to a distributed display architecture where the accessory provides an extended viewing area in a different spatial location. This allows detailed content to be rendered at larger dimensions on the accessory while the mobile device maintains its compact form factor for portability.

AI summary
Method, system, and device for remote operation of a wireless communication device. The method for remote operation of a wireless communication device using an accessory involves establishing a communication channel between the accessory and the wireless communication device, providing output to a user on the accessory, receiving user input on the accessory, processing the user input and generating control signals for transmission to the wireless communication device to initiate one or more actions on the wireless communication device. The accessory comprises a touchscreen for presenting information to a user and receiving user input. The accessory may optionally be a hinged accessory with a dual touchscreen.
