Taking Others' Perspectives Enhances Situation Awareness in the Smart Home Interface

Area of Science:

• Human-Computer Interaction
• Smart Home Technology
• Cognitive Psychology

Background:

• Smart homes involve interconnected devices used by multiple individuals.
• Shared device use complicates user interaction due to differing preferences and usage patterns.
• This complexity can lead to reduced situation awareness for co-users.

Purpose of the Study:

• To investigate the impact of spontaneous visuospatial perspective-taking on smart home situation awareness.
• To determine if affordances of other users can trigger spontaneous perspective-taking.
• To assess if adopting others' perspectives enhances situation awareness in a smart home interface.

Main Methods:

• Replicated previous research on affordances eliciting visuospatial perspective-taking.
• Developed a mock-up smart home interface to test perspective-taking effects.
• Measured participants' situation awareness when adopting different user perspectives.

Main Results:

• Adopting co-users' perspectives facilitated easier perception of device information.
• Understanding of devices primarily used by the self was lower when viewing from another's perspective.
• Spontaneous visuospatial perspective-taking was influenced by the affordances of other users.

Conclusions:

• Considering co-users' perspectives can enhance smart home situation awareness.
• Interface design should account for shared usage patterns to optimize user experience.
• Further research is needed to explore the nuances of perspective-taking in shared smart environments.
