Claims

C1strongest claim

Although robot assistance increased completion time, most participants preferred collaboration: 67% preferred proactive behavior and 78% judged it most useful. These results suggest that timely proactive support can improve user experience in controlled collaborative tasks.

C2weakest assumption

The single controlled memory-tower task with 18 participants is representative of broader human-robot collaboration scenarios and that preference ratings translate to real-world usefulness.

C3one line summary

Proactive robot assistance was preferred by 67% of participants and rated most useful by 78%, even though it increased completion time compared to working alone.
