Presence-Mimicking Lighting Control Without Cold-Start Learning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing presence mimicking technologies, such as smart lighting systems, can be predictable and detectable, making it easy for observers to distinguish between simulated and actual occupancy patterns, and they often require a learning phase before becoming operational, which can lead to a 'cold start' issue.
Innovation Solution
A computer system that mimics the illumination settings of a user in one environment by mirroring the behavior of a similar user in another environment, eliminating the need for a learning phase and making the simulation more realistic by selecting a matching sequence of illumination settings based on profiles that include room types, luminaire counts, and usage patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If schedule-based presence simulation is used, then the system can provide automated lighting control, but the pattern becomes detectable and distinguishable from actual occupancy
Solution Approach 1:
The system copies the lighting behavior patterns from occupied environments to unoccupied environments. By replicating actual user lighting sequences from similar homes, the system creates indistinguishable presence simulations rather than using detectable automated schedules
Solution Approach 2:
The system performs preliminary data collection and pattern analysis from occupied environments before implementing the simulation. By gathering lighting behavior data in advance from similar homes, the system prepares authentic occupancy patterns that will be applied when the target environment is unoccupied
2Adaptability or versatility
If smart lighting systems learn from user behavior, then the system can adapt to occupancy patterns, but a cold start problem occurs requiring initial information gathering
Solution Approach 1:
The system uses an intermediary approach by borrowing lighting behavior patterns from similar occupied environments rather than learning exclusively from the target environment. This intermediary data source allows immediate adaptation without requiring a cold start learning phase in the unoccupied environment
Solution Approach 2:
The system applies universal lighting behavior patterns collected from multiple similar environments that can be adapted to different target environments. By creating a library of occupancy patterns from various homes, the system can immediately apply appropriate patterns to any unoccupied environment without environment-specific learning
3Difficulty of detecting and measuring
If randomized schedules are used to prevent detection, then variability is introduced, but detectable patterns may still be exhibited over time
Solution Approach 1:
Instead of generating randomized schedules, the system copies authentic lighting sequences from occupied environments. These copied patterns maintain the natural consistency and variability of real human behavior without exhibiting artificial randomization patterns that could be detected over time

AI summary
A presence mimicking system comprises a first lighting system (1A) arranged to illuminate a first environment and a second lighting system (1B) arranged to illuminate a second environment. A computer system configured to receive from the first lighting system an indication of a sequence of illumination settings, at least some of which have been applied to the first lighting system by at least one user when present in a first environment illuminated thereby. The computer system is configured, in response to a mimic instruction, to mimic in the unoccupied second environment the presence of the at least one user of the first environment, by applying a matching sequence of illumination settings to the second lighting system, wherein the computer system is configured to select the first lighting system for use in the presence mimicking from a set of candidate lighting systems, by comparing a profile of the second lighting system with profiles of the candidate lighting systems.
