Comparing Social Robot, Screen and Voice Interfaces for Smart-Home Control
summary
A physical home-control robot called vo robot is built (five DOF, Raspberry Pi 2, chest camera, low‑fidelity TFT) and compared to a voice speaker, wall touch‑panel and mobile app in a within‑subjects study with 43 participants performing a word‑copy dual task. Key findings: the robot yields highest flow and situation awareness but lowest usability, screens give highest usability and best task performance, the mobile app is most distracting, and voice control produces low situation awareness and unease.
