Projector-Based Mobile Interface Stitching for Expanded Display Area
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Small screen sizes and input methods of hand-held mobile devices hinder user experience by limiting the ability to display and interact with information effectively, as users desire larger display screens for easier interaction with their devices and other nearby devices.
Innovation Solution
A mobile device uses a projector to create a larger external projection area that functions as a touch or multi-touch user interface, allowing users to interact with the device and potentially connect with neighboring devices to create a combined seamless user interface, enhancing interaction and collaboration through stitching projection areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If hand-held mobile devices use small physical screens, then the device size remains compact and portable, but the display area and interaction capability are limited
Solution Approach 1:
The patent extends the user interface from the two-dimensional physical screen into the third spatial dimension by projecting the display onto external surfaces. The projector casts images onto walls, tables, or other nearby surfaces, effectively utilizing external space to expand the display area without increasing the physical dimensions of the mobile device itself.
Solution Approach 2:
The patent introduces an intermediary projection surface that acts as a mediator between the mobile device and the user. Instead of directly interacting with the small physical screen, users interact with the projected image on an external surface, which serves as an intermediate interface that bridges the gap between the compact device and the need for larger interaction area.
2Adaptability or versatility
If multiple mobile devices are used to create a combined user interface, then the interaction capability and display area are enhanced, but the system complexity and coordination requirements increase
Solution Approach 1:
The patent merges multiple mobile devices into a unified collaborative system where each device projects its own interface onto a shared external surface. The projection areas of multiple devices overlap or adjacent on the external surface, creating a combined user interface that leverages the computational resources and display capabilities of all participating devices while presenting a cohesive interaction experience to the user.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution provides a larger interactive surface area, enabling users to perform complex operations and collaborate more effectively across multiple devices, improving the user experience by expanding the display and interaction capabilities beyond the physical screen limitations.
Implementation Method 1
uses a projector to illuminate a projection area external to the mobile device
Implementation Method 2
uses the projection area as a user interface. The user interface can function as a touch screen or multi-touch screen and a user's interaction with the projection area can be captured by a camera of the mobile device
