Determine whether interaction modality affects task execution time

Determine whether conversational, hybrid, and traditional graphical interaction modalities produce different task execution times when users perform CRUD tasks in an LLM-augmented content management system.

Background

The study compared Traditional-Only, AI-First, and Hybrid interaction conditions for CRUD tasks in the delegAgents content management system. Although AI-assisted conditions reduced clicks, navigations, and scrolling, the study found no statistically significant difference in task duration across conditions. The authors therefore characterize the relationship between interaction modality and execution speed as unresolved rather than established, particularly because the descriptive timing results do not conclusively support either a speed advantage or disadvantage for conversational interaction.
