Innovation Solution
A system architecture that includes an adaptive light source, user computer system, and server communicatively coupled via a network, enabling user input recognition through voice commands and gestures, with optical and audio sensors to steer projectors and adjust light characteristics based on user requests, allowing for dynamic light projection in response to user interactions and environmental context.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple light sources are used to create flexible lighting arrangements, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple light sources into a single integrated projector unit that can project light to multiple locations simultaneously. The projector integrates the light source, optical system, and control electronics into one device, eliminating the need for separate control systems for each light source while maintaining the ability to illuminate multiple areas flexibly.
Solution Approach 2:
The projector serves multiple functions: it acts as both a light source and a projection device, can illuminate different areas by changing projection angles, and can be controlled through multiple interfaces (voice commands, gestures, remote control). This multi-functionality reduces the need for multiple specialized devices while maintaining lighting flexibility.
2Adaptability or versatility
If manual control of multiple light sources is required, then ease of operation deteriorates, but adaptability is improved
Solution Approach 1:
The system incorporates sensors (cameras, microphones, motion detectors) that automatically detect user presence, gestures, and environmental conditions. The projector autonomously adjusts lighting parameters based on detected inputs without requiring manual intervention, making the system both adaptable and easy to operate.
Solution Approach 2:
The system uses sensors to continuously monitor the environment and user actions, then adjusts lighting parameters in real-time based on this feedback. Voice recognition and gesture detection provide continuous feedback loops that allow the system to adapt to user needs automatically, eliminating complex manual controls while maintaining high adaptability.
3Adaptability or versatility
If real-time user input recognition is implemented, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent introduces a microcontroller as an intermediary that processes sensor inputs (voice, gestures, motion) and translates them into control signals for the projector. This intermediary layer simplifies the system architecture by centralizing the processing logic and providing a clear interface between the sensors and the projection system, reducing overall complexity while enabling real-time user interaction.
Data Source
AI summary
Methods, apparatuses and systems for adaptive light projection are described herein. According to embodiments of the disclosure, optical data of a physical space around a user is received. Light from a light source is then projected onto a projection area that is determined based, at least in part, on the received optical data.User commands may include requests to locate and/or track objects within the physical space around the user. User commands may comprise a combination of the audible user command and a physical user gesture—e.g., a gesture identifying an object or a surface to receive the projected light.
