Projected Screen External-Object Identification for Dynamic Sizing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices lack the ability to dynamically adjust the size of projected screens based on the location and interaction of external objects, leading to suboptimal user experiences.
Innovation Solution
The electronic device incorporates a projection assembly and a camera system that allows it to project a screen, activate a camera in a direction different from the projection direction, and adjust the screen size based on the location of external objects using sensors and image processing to enhance user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the electronic device projects a screen on a surface, then the displaying area is formed on the surface, but the device cannot identify external objects and dynamically adjust screen size
Solution Approach 1:
The electronic device integrates multiple functions into a single system: the projection assembly creates displaying areas on surfaces, the camera system detects external objects and contact points, and the processor coordinates both systems to dynamically adjust screen size and position based on detected objects. This multi-functional integration enables the device to adapt to different usage scenarios automatically.
Solution Approach 2:
The camera system continuously monitors the environment and provides feedback about external objects and contact points to the processor. Based on this feedback, the processor adjusts the projection assembly's output to change screen size and position, creating a closed-loop control system that responds to real-time conditions.
2Measurement precision
If the camera is positioned to detect external objects, then object identification is enabled, but the camera cannot simultaneously capture contact points on the projected surface
Solution Approach 1:
The system resolves the camera positioning conflict by utilizing spatial dimensionality. The camera is positioned to detect objects in three-dimensional space while the projection assembly creates two-dimensional displaying areas on surfaces. The processor integrates information from both perspectives, mapping object detection data with surface contact point data to achieve precise interaction recognition.
3Ease of operation
If the screen size is fixed, then the projection system is simple, but the user experience is suboptimal when external objects are present
Solution Approach 1:
The projection system transitions from a static, fixed-screen configuration to a dynamic system where the screen size and position automatically adjust based on detected external objects and user interactions. The processor continuously modulates the projection assembly's output in response to camera input, creating an adaptive display that responds to changing environmental conditions.

AI summary
An electronic device includes: an interface; a camera; a projection assembly; memory comprising one or more storage media storing instructions and at least one processor comprising processing circuitry, wherein the instructions, when executed by the at least one processor individually or collectively, cause the electronic device to: project, by controlling the projection assembly, a screen obtained through the interface; activate, in a state of projecting the screen receiving an identification of a contact point on a surface at a displaying area formed by the projection assembly, the camera positioned toward a second direction different from a first direction of the projection assembly; and based on identifying an external object from information obtained using the activated camera and based on a location of the external object with respect to the surface, change a size of the screen.
