1.mobile devices, sensors Flashcards
three purposes of using mobile sensors in medicine?
monitoring health parameters like heart rate, glucose levels, and physical activity
What is Ambient Assisted Living (AAL)?
AAL refers to age-appropriate assistance systems for the elderly, aimed at supporting their independence and health.
What are the goals of AAL?
supporting mobility and cognitive function,
preventing falls, aiding in daily life tasks,
preventing social isolation.
What challenges are associated with mobile devices in AAL?
ease of use for the elderly, simple charging and cleaning, and avoiding interference with daily activities
key considerations before using fitness trackers in research
sensor quality
data privacy
the ability to export data in standard formats.
Explain the “open loop” and “closed loop” systems with an example.
An “open loop” system operates without feedback (e.g., manual insulin injection), while a “closed loop” system adjusts based on feedback (e.g., an insulin pump adjusting dosage based on glucose sensor data).
explain the use of telemedicine in emergency situations.
Telemedicine allows for remote consultation and diagnosis, enabling timely medical intervention in emergencies.
What is the Hawthorne Effect and its relevance in medical research
phenomenon where study subjects change their behavior because they know they are being observed
How can the Hawthorne Effect be reduced in medical research?
By discarding the values of the first hours or first day of observation.
What technology is commonly used in AAL for fall detection
Accelerometers, which can detect falls and allow location detection.
Linking Mobile Phones to Mobile Sensors
Mobile phones act as connectors to the wide-area network for mobile sensors. Due to the high power consumption and short range of mobile sensors, a relay (like a cellphone) is often required for remote queries or alerts.
Mobile Devices for Elderly People: What to Consider?
When integrating mobile devices in Ambient Assisted Living (AAL), considerations include usability for the elderly, simple charging and cleaning, minimal interference with daily activities, and avoiding stigmatization.
Privacy of Monitoring Devices for Elderly People
Privacy concerns are significant in AAL. Perceived privacy issues can affect acceptance, so transparency is key
Challenges in Interface Design for Elderly People
easy usability, limit the possibility of errors, avoid cognitive overload, keep options limited, and ensure linear dialogues without parallel tasks
