Understanding the Benefits of Sensible Agent Over Traditional AR Assistants
In the ever-evolving world of technology, comparing innovative tools provides valuable insights into their effectiveness. This blog post explores how Sensible Agent outperforms traditional voice-controlled AR assistants based on cognitive load, usability, and user preference.
Key Findings from the Comparison
Cognitive Load Reduction
One of the most significant findings in our study was the marked reduction in cognitive workload when using Sensible Agent. The data derived from the NASA Task Load Index (NASA-TLX) indicated an average mental demand score of 21.1 for Sensible Agent, in stark contrast to 65.0 for the conventional baseline. This difference is statistically significant (๐ < .001), demonstrating that Sensible Agent effectively minimizes the mental effort required to engage with the system.
Usability Insights
When it comes to usability, both Sensible Agent and the traditional AR assistant performed admirably. The System Usability Scale (SUS) scores showed no significant difference (๐ = .11). However, participants displayed a notable preference for Sensible Agent, scoring it an average of 6.0 on a 7-point scale compared to 3.8 for the baseline (๐ = .0074).
Interaction Time Considerations
In terms of interaction time, the traditional AR assistant displayed a faster response rate, logging an average time of 16.4 seconds, whereas Sensible Agent took approximately 28.5 seconds. This delay is a result of Sensible Agent’s unique two-step interaction flow, which involves the agent proposing an action that the user must confirm. Despite the longer interaction time, the strong user preference for Sensible Agent suggests that the trade-off is acceptable, particularly in social environments where user effort and discretion are key.
Conclusion
The findings clearly indicate that while Sensible Agent may take slightly longer to respond, it offers substantial benefits in reducing cognitive load and enhancing user preference. These advantages make it a compelling choice in the realm of voice-controlled AR assistants, particularly in contexts where minimizing mental effort is paramount.
