IoT Message Interceptor for Digital Signage Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Developing and testing digital signage systems that utilize IoT device sensor data is challenging due to the need for specific conditions to trigger sensor messages, making it inconvenient and impractical for marketers to test or demonstrate the system without direct control over IoT device sensor outputs.
Innovation Solution
A message interceptor module intercepts and edits IoT device sensor messages, allowing users to simulate desired data values through a user interface, which are then transmitted to digital signage display modules, enabling control over the generation and rendering of content without requiring actual sensor data conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If IoT device sensors are physically acted upon to generate specific data values, then the digital signage can be tested with desired sensor outputs, but the testing process becomes inconvenient and impractical
Solution Approach 1:
The patent introduces a message interceptor as an intermediary component that sits between the IoT device sensors and the digital signage application. This interceptor captures sensor messages, allows marketers to edit the sensor data values, and forwards the modified messages to the application. This resolves the contradiction by providing reliable testing through controlled data injection while maintaining ease of operation through a user-friendly editing interface, eliminating the need for physical manipulation of sensors.
2Ease of operation
If marketers have direct control over IoT device sensor messages, then testing and development becomes easier, but the system architecture becomes more complex
Solution Approach 1:
The message interceptor serves as a controlled intermediary that provides marketers with editing capabilities while maintaining a clean separation between the IoT device layer and the digital signage application. The interceptor handles the complexity of message interception, editing, and forwarding, allowing marketers to control sensor messages without directly modifying the underlying system architecture. This resolves the contradiction by enabling ease of operation through a simplified interface while containing the complexity within the interceptor component.
3Measurement precision
If specific conditions are required to trigger IoT sensor messages, then accurate sensor data is obtained, but the ability to test various scenarios is limited
Solution Approach 1:
The message interceptor enables marketers to edit sensor data values in captured messages, allowing them to simulate various sensor conditions without requiring actual physical changes to the environment. This resolves the contradiction by maintaining measurement precision through accurate sensor message formats while dramatically improving testing versatility, as marketers can now test any scenario by simply editing the data values in the intercepted messages.

AI summary
Techniques are disclosed for the simulation of Internet of Things (IoT) device messages to control the generation and rendering of digital signage on a display module. A methodology implementing the techniques according to an embodiment includes intercepting messages that are transmitted from the devices to the display modules, and extracting or otherwise accessing sensor data from the intercepted messages. The sensor data can be provided to a user interface configured to allow a user to edit or manipulate the sensor data. A modified or transformed message is generated, based on the intercepted message and the edited sensor data. The modified or transformed message is transmitted to the display module, which is configured to render digital signage based on the content of the message. These techniques enable the user to visualize and evaluate alternative signage renderings in a relatively convenient manner by manipulating the sensor data reported from the IoT devices.
