Service Negotiation Method for Adaptive Terminal Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current interfaces for service delivery to terminals fail to adapt effectively to the diverse capabilities and contexts of terminals, leading to underutilization of terminal capacities and inadequate interaction experiences, especially for users with disabilities and varying use contexts.
Innovation Solution
A method of negotiation where a server sends a set of interaction proposals to a terminal, allowing it to choose the best interaction mode based on its capabilities and user preferences, dynamically adapting the interface to optimize interaction and accommodate user handicaps and contexts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a service delivers content adapted to terminal display capabilities, then content compatibility is improved, but interaction capability is reduced
Solution Approach 1:
The service delivery system segments the interaction model into multiple independent interaction proposals, each describing a different set of stimuli and interaction commands. The terminal can select and accept one or more proposals based on its capabilities, enabling both content adaptation and interaction capability to coexist through modular interaction options.
Solution Approach 2:
The system dynamically adapts the interaction mode by allowing the terminal to negotiate and select from multiple interaction proposals during service delivery. This dynamic selection process enables the terminal to choose the most suitable interaction mode based on its current capabilities and context, rather than being fixed to a single interaction paradigm.
2Adaptability or versatility
If a service uses generic interaction modes for universal access, then accessibility is improved, but terminal capability utilization is reduced
Solution Approach 1:
The service delivery system provides universal access by offering multiple interaction proposals that can accommodate different terminal types and user needs. Each proposal represents a different interaction paradigm, ensuring that services remain accessible across diverse platforms while allowing advanced terminals to utilize richer interaction capabilities when available.
Solution Approach 2:
The system changes interaction parameters by providing different stimulus sets and command structures in each interaction proposal. Terminals can adjust their interaction parameters based on their capabilities, selecting proposals that optimize both accessibility and capability utilization without requiring a fixed interaction model.
3Ease of operation
If a service provides rich interaction options, then interaction potential is improved, but negotiation complexity is increased
Solution Approach 1:
The negotiation process is segmented into discrete interaction proposals, each with a defined set of stimuli and commands. This segmentation simplifies the negotiation complexity by breaking down rich interaction options into manageable, independently negotiable units, making it easier for terminals to evaluate and select appropriate interaction modes.
