Solution Overview
Problem
Existing lighting systems struggle to effectively attract and engage the attention of individuals in environments like retail spaces and museums, especially when they are distracted by smartphones, as they rely on initial interest detection to determine appropriate light displays.
Innovation Solution
A configurable lighting system that uses a presence detector and controller to generate a spotlight effect from a location proximal to the individual towards a desired location of interest, incorporating a gaze detection mechanism to ensure the light effect is within the individual's field of view and dynamically adjustable to redirect attention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the lighting system waits for initial interest detection before activating light displays, then the system can determine appropriate light displays based on user engagement, but the system fails to initially attract the attention of users who are distracted or engaged with other activities
Solution Approach 1:
The system performs preliminary actions by detecting user presence and predicting field of view before activating light displays. The presence detector identifies users in the detection area, and the controller predicts their field of view based on motion direction, enabling the system to proactively position light effects within the predicted field of view rather than waiting for user engagement
Solution Approach 2:
The system introduces an intermediary prediction mechanism that bridges the gap between presence detection and light display activation. The controller predicts the user's field of view based on motion direction data, serving as an intermediary step that enables appropriate light display positioning without requiring direct user engagement detection
2Ease of operation
If the system uses a presence detector to identify user location and motion direction, then the system can determine user position and predict field of view, but the system complexity increases with additional detection and control components
Solution Approach 1:
The presence detector serves multiple functions: it detects user presence, determines motion direction, and provides data for field of view prediction. The controller also performs multiple roles including configuring light sources, predicting field of view, and determining when to activate light effects, reducing the need for separate dedicated components for each function
Solution Approach 2:
The system uses the motion direction data detected by the presence detector to self-determine the user's field of view without requiring separate gaze detection hardware. The controller automatically processes the motion direction information to predict where the user is looking, enabling the system to serve its own detection needs

AI summary
The invention provides a lighting system (10) for generating a configurable spotlight effect adapted to direct the attention of an individual from an initial location (34) to a defined second location (36). In particular, the invention comprises a presence detector (14) for detecting motion of an individual (22) at a detection location (28) within a detection area, and for detecting in which direction the individual (22) is moving. A configurable light source (12) is controlled by a controller (18) to create a light effect (30, 32) from a first location (34) in front of the individual (22) based on the direction of the individual (22) toward a defined location (36) so as to thereby draw the attention of the user toward said defined location.
