Electronic tracking system and wandering in Alzheimer's disease: a case study

Area of Science:

• Gerontology
• Human-Computer Interaction
• Behavioral Science

Background:

• Wandering is a significant behavioral disorder in Alzheimer's disease and other dementias, increasing risks for patients and stress for caregivers.
• Existing geolocation tracking devices for managing wandering often neglect the crucial input of end-users in their development.
• This gap highlights a need for user-centered design in assistive technologies for dementia care.

Observation:

• This study explored the needs and perceptions of individuals with dementia and their caregivers regarding existing tracking devices.
• A dyad case study evaluated the acceptability and usability of a Global Positioning System (GPS) device with telephony and data transfer capabilities.
• User feedback was collected on their needs, perceptions, and impressions of the tested device's functionality.

Findings:

• The patient found the tested GPS device too bulky and aesthetically unappealing, and could not assess its functionality.
• The caregiver spouse reported malfunctions and usability issues, deeming the device unsuitable for their needs.
• Current tracking systems do not adequately address the practical requirements and preferences of individuals with dementia and their caregivers.

Implications:

• Involving end-users, including patients and caregivers, in the co-design process is crucial for developing effective and tailored wandering management technologies.
• A person-centered approach is essential for creating assistive devices that truly meet the needs within dementia care.
• Future technology development must prioritize user feedback and usability to ensure the acceptance and efficacy of wandering solutions.
