Evaluation of a Mobile Emergency Alert System Using GAQM

Area of Science:

• Human-Computer Interaction
• Mobile Health Technology
• Usability Engineering

Background:

• Mobile emergency alert systems offer potential for enhanced safety and autonomy.
• System success hinges on critical factors like usability, user experience (UX), and user acceptance.
• Evaluating early-stage mobile health systems in domestic settings presents unique challenges.

Purpose of the Study:

• To present a structured evaluation methodology for an early-stage mobile emergency alert system prototype.
• To demonstrate a transferable and participatory approach for assessing mobile health systems.
• To identify key usability attributes and metrics for emergency alert systems.

Main Methods:

• Utilized the Goals, Attributes, Questions, Metrics (GAQM) framework for structured evaluation.
• Integrated both qualitative and quantitative research methods.
• Conducted the evaluation within a domestic environment to simulate real-world usage.

Main Results:

• The GAQM framework provided a systematic approach to identify system strengths and weaknesses.
• Participatory methods yielded rich insights into user needs and expectations.
• The evaluation highlighted specific areas for improving the system's usability and UX.

Conclusions:

• The proposed GAQM-based evaluation methodology is effective for early-stage mobile health systems.
• A participatory, mixed-methods approach is crucial for assessing systems in domestic environments.
• This methodology can be adapted for evaluating diverse mobile health technologies to ensure user acceptance and effectiveness.
