Broadcast Trigger Signal for Synchronized Haptic Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In haptic feedback systems, two-way communication between control apparatuses and haptic-feedback presenting devices leads to increased system load and synchronization issues, as each device requires individual communication, resulting in varying presentation timings.
Innovation Solution
A content providing system that uses a transmission apparatus to broadcast a trigger signal, allowing reception apparatuses to synchronize content presentation without the need for two-way communication, with the control apparatus managing trigger signals to ensure consistent reproduction times across multiple devices.

Engineering Contradiction Analysis
1Reliability
If two-way communication is used between control apparatus and haptic-feedback presenting devices, then the control apparatus can instruct presenting timing of haptic feedback, but the system load increases as the number of devices increases
Solution Approach 1:
The system separates the control function from the execution function. The control apparatus generates and transmits trigger signals, while each reception apparatus independently executes the haptic feedback based on its own stored content and the received trigger signal. This segmentation eliminates the need for continuous two-way communication and reduces system load.
Solution Approach 2:
Content is stored in advance in the storage part of each reception apparatus. The trigger signal only needs to indicate the starting position, and the reception apparatus automatically retrieves and executes the pre-stored content. This preliminary preparation eliminates the need for real-time content transmission and reduces communication overhead.
2Reliability
If two-way communication is used between control apparatus and haptic-feedback presenting devices, then the control apparatus can instruct presenting timing of haptic feedback, but the presenting timings of haptic feedback become different across devices
Solution Approach 1:
The system merges the content storage into each reception apparatus rather than transmitting it from the control apparatus. Each device has its own storage part containing the content, and all devices receive the same trigger signal format, ensuring they execute content at synchronized timing based on their local copies.
Solution Approach 2:
The content is copied to each reception apparatus's storage part in advance. Each device operates independently with its own copy, eliminating communication delays and synchronization issues that would occur with centralized content transmission. The trigger signal simply activates the local copy at the appropriate timing.

AI summary
To provide a content providing system preferably providing a plurality of users with content. A content providing system according to the present technology includes a transmission apparatus, a control apparatus, and a plurality of reception apparatuses. The transmission apparatus transmits a trigger signal by broadcasting the trigger signal. The control apparatus controls the transmission apparatus. Each of the plurality of reception apparatuses includes a signal-reception part that receives the trigger signal, a storage part that stores content, a content presenting part that presents the content to a user, and a control part that controls the content presenting part on the basis of the trigger signal.
