Location-Aware Task Devices for Reliable Crowd Image Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for displaying images in crowds, such as using colored boards or light-emitting diodes, require strategic collaboration among large groups of patrons, which is often difficult and unreliable, leading to anomalies in the displayed image.
Innovation Solution
A task performance system where each device determines its location using transmitters that periodically transmit timing and position information, allowing it to perform tasks based on its location within a defined area, such as illuminating light sources or making sounds, without the need for precise coordination among individuals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual methods using colored boards or placards are used, then image display is achieved, but reliability deteriorates due to difficult and unreliable group collaboration
Solution Approach 1:
Each patron's device automatically determines its own location using transmitters and independently performs the appropriate task (displaying the correct color/illumination) based on its determined position. This eliminates the need for group coordination while maintaining reliable image display, as each device serves itself according to its location.
Solution Approach 2:
The manual mechanical system of physically holding placards is replaced with an automated electronic system where devices automatically determine location and control illumination or display elements. This substitution eliminates human coordination requirements while improving reliability.
2Reliability
If wristbands with LEDs are distributed to patrons, then active image display is achieved, but reliability deteriorates due to lack of control over patron location
Solution Approach 1:
Transmitters continuously provide location information to each device, which automatically uses this feedback to determine its position and perform the correct task. This closed-loop feedback system ensures reliable image display by continuously updating devices with their location information, eliminating the need for manual location control.
3Manufacturing precision
If precise coordination among large groups is required, then image accuracy is improved, but device complexity increases due to coordination mechanisms
Solution Approach 1:
The coordination system is segmented into independent autonomous devices, each determining its own location and performing its own task. This segmentation eliminates the need for complex centralized coordination mechanisms while maintaining image accuracy, as each segment (device) independently contributes to the overall image based on its location.

AI summary
A task performance system and method including multiple transmitters and multiple task devices distributed in a local area. Each task device includes communication circuitry, a memory, a controller, and output circuitry. The communication circuitry receives timing information and position information from the transmitters. The transmitters may also transmit task information including task location parameters that define the task area. The task area is divided into subblocks each having a corresponding task value. The controller uses the received information to determine its location and accesses the memory when located within the task area to retrieve a corresponding task value based on subblock location. The task information includes task values which may define a different task for each subblock. The controller activates output circuitry in accordance with the task value to perform a corresponding task. The output circuitry may include one or more light sources, a speaker, a vibration device, etc.
