Solution Overview

Problem

Existing chatbot-style user interfaces impose a significant burden on users due to the need to make multiple selections from a large number of input candidates, leading to cumbersome screens and inefficient interactions.

Innovation Solution

An information processing apparatus equipped with a controller that generates and manages input candidates using generative AI, determines whether the number of selections is limited to one based on dialogue context, and adjusts the display mode accordingly, thereby reducing the number of candidates and simplifying the user interface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple input candidates are provided to users in chatbot-style UI, then the system offers more comprehensive options and improves response accuracy, but the user input burden increases and the interface becomes cumbersome

Engineering Contradiction:
Improveresponse accuracyVSAvoiduser input burden
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system dynamically adjusts the number of input candidates displayed to users based on the dialogue context and selection constraints. The controller automatically determines whether the number of selections is limited to one or multiple, and generates display information indicating the appropriate display mode. This dynamic adaptation allows the interface to provide comprehensive options when needed while simplifying the display when fewer options are appropriate, thereby resolving the contradiction between response accuracy and user input burden

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the parameter of the number of displayed input candidates based on dialogue analysis. When the dialogue context indicates that only one selection is needed, the system limits the number of candidates to one, reducing the user input burden. When multiple selections are appropriate, the system provides more candidates to improve response accuracy. This parameter adjustment resolves the technical contradiction by adapting the interface to the specific context

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If the system provides a fixed large number of input candidates, then comprehensive options are available, but the interface complexity increases and user experience deteriorates

Engineering Contradiction:
Improveoption comprehensivenessVSAvoidinterface complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The interface complexity is made dynamic by automatically adjusting the number of displayed candidates based on dialogue context. The controller analyzes the conversation and determines the appropriate number of selections, then generates corresponding display information. This dynamic approach ensures the interface remains simple when appropriate while providing comprehensive options when needed, resolving the contradiction between adaptability and interface complexity

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system performs self-service by automatically determining the appropriate number of input candidates to display without requiring manual configuration or user input. The controller autonomously analyzes the dialogue context and adjusts the candidate count accordingly, allowing the system to adapt to different situations while maintaining a simple interface, thus resolving the contradiction between comprehensiveness and complexity

Inventive Principle:
Principle #25Self-service

AI summary

A controller (12) of an information processing apparatus (10) generates (S101) a message (41) to a user of a chatbot, automatically generates (S102) a plurality of next input candidates (43-1, 43-2, 43-3, 43-4) for the user in response to the message (41) according to content of a dialogue with the user, automatically determines (S103) whether a number of selections to be made by the user from among the input candidates (43-1, 43-2, 43-3, 43-4) is limited to one according to the content of the dialogue with the user, and generates (S104) display information indicating a display mode for the input candidates (43-1, 43-2, 43-3, 43-4) according to whether the number of selections is limited to one.
