Mobile Projector Positioning for Adaptive Extension Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile robots lack the capability to function as projectors, limiting their versatility in displaying images of various sizes and positions, unlike fixed displays, and there is a need for integrating a projector into mobile robots to enhance their functionality.
Innovation Solution
A mobile projector device equipped with a drive assembly, transceiver, projector, memory, and processor that allows it to determine projection positions, control image projection, and adjust based on environmental and user interactions, including obstacle detection and face recognition, to function as an extension display device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a mobile robot includes a fixed display, then it can display content, but it is limited to a single fixed position and size like a mobile terminal
Solution Approach 1:
The mobile robot is equipped with both a display unit for fixed-position display and a projector unit for flexible projection display, enabling the device to function in multiple display modes (fixed display, projection display, extension display) to serve various application scenarios
2Adaptability or versatility
If a mobile robot integrates a projector, then it can display images of various sizes and positions, but the device complexity increases
Solution Approach 1:
The display unit and projector unit are integrated into a single mobile robot system with a unified control unit that manages both components, allowing coordinated operation and reducing overall system complexity despite the addition of multiple display functions
3Measurement precision
If the mobile projector determines projection position based on source device position information, then it can accurately position the projection, but it requires additional position information processing
Solution Approach 1:
A transceiver unit is introduced as an intermediary component that receives position information from the source device and transmits it to the control unit, which then processes the information to determine the projection position, distributing the processing load and simplifying the control architecture

AI summary
A mobile projector device includes a drive assembly including at least one wheel, a transceiver, a projector, memory storing instructions, and at least one processor, where the instructions, when executed by the at least one processor, cause the mobile projector device to determine whether to set the mobile projector device as an extension display device associated with a source device, receive, through the transceiver and from the source device, information about an image based on determining to set the mobile projector device as the extension display device, determine a projection position of the mobile projector device for projecting the image based on position information about the source device, and control the projector to project the image while the mobile projector device is at the projection position.
