Solution Overview

Problem

Traditional multimedia interaction systems fail to ensure that multimedia interactions conform to normal user experiences, as they cannot determine the relative position of electronic devices, leading to unexpected interactions that violate design rules.

Innovation Solution

A multimedia interaction system with a location detection circuit that dynamically detects spatial locations and orientations of electronic devices, transmitting this information wirelessly, and only allows multimedia operations if the relative position between devices satisfies a predetermined condition.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If electronic devices are designed to transmit/receive signals to/from various directions, then signal transmission quality is improved, but unexpected multimedia interactions occur that violate design rules

Engineering Contradiction:

Improvesignal transmission qualityVSAvoidunexpected multimedia interactions

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The system implements feedback by having the receiving-end electronic device send relative position information back to the transmitting-end device. This feedback loop enables the transmitting-end device to determine whether the receiving-end device is in a valid interaction zone, allowing the system to filter out unexpected interactions while maintaining signal transmission quality in all directions.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent introduces an intermediary mechanism in the form of a relative position determination module that acts as a mediator between signal transmission and interaction validation. This intermediary checks the spatial relationship between devices before allowing multimedia interactions, preventing unauthorized interactions while preserving the underlying communication capability.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If electronic devices are restricted to transmit/receive signals only to/from a specific direction, then unexpected interactions are prevented, but signal transmission ability and receiving range are severely influenced

Engineering Contradiction:

Improveunexpected multimedia interactionsVSAvoidsignal transmission ability

Core Design Contradiction:

Object-affected harmful factorsVSAdaptability or versatility

Solution Approach 1:

The system segments the interaction validation process from the signal transmission process. Signal transmission operates in all directions without restriction, while interaction validation is segmented into a separate checking mechanism that evaluates relative position information. This segmentation allows full signal transmission capability while preventing unauthorized interactions through logical filtering.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system dynamically determines interaction validity based on real-time relative position information between devices. Rather than statically restricting signal transmission directions, the system adaptively validates interactions based on current spatial relationships, maintaining transmission versatility while preventing unexpected interactions through dynamic conditional logic.

Inventive Principle:

Principle #15Dynamics

3Reliability

If the transmitting-end electronic device determines relative position among devices, then multimedia interaction results conform to design rules, but device complexity increases

Engineering Contradiction:

Improvemultimedia interaction results conformityVSAvoidtransmitting-end device functionality

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

Instead of having the transmitting-end device determine relative position (which would increase its complexity), the patent inverts the approach by having the receiving-end device determine and report its own relative position to the transmitter. This inversion shifts the computational burden to the receiving-end device, maintaining interaction reliability while keeping the transmitting-end device relatively simple.

Inventive Principle:

Principle #13The other way round (Inversion)

AI summary

A multimedia interaction system is disclosed, including: a plurality of member electronic devices; a plurality of displays respectively arranged on the member electronic devices; and a location detection circuit configured to operably detect respective member electronic device's spatial position and orientation dynamically and to transmit detection results to at least one of the member electronic devices. When an user instructs a source electronic device of the member electronic devices to transmit a target image object toward a target direct, a candidate electronic device of the member electronic devices would execute a target command corresponding to the target image object to utilize a corresponding display to perform a multimedia operation corresponding to the target image object only if a relative position between the candidate electronic and the target direct satisfies a predetermined condition.
