LEAR: A GPS-Based Solution for Independent Mobility in Individuals with Cognitive or Functional Impairments

LEAR is a wearable device designed to support individuals with cognitive or age-related impairments and their caregivers (family members, informal or professional caregivers). Its primary objective is to enable users to spend time outdoors independently, without the constant physical presence of a caregiver, a precaution often necessary due to risks such as disorientation, confusion, or difficulty with navigation, which can arise from various cognitive or functional impairments. LEAR addresses this challenge through a GPS-based monitoring system that notifies caregivers when the user exits a predefined safe zone or requests assistance due to disorientation or uncertainty. LEAR also integrates Points of Interest (POIs) to monitor whether users follow a daily routine and visit key locations deemed relevant by the caregiver. Deviations from expected behaviour - such as missing a routine stop or remaining unusually long at a location - trigger intelligent notifications. LEAR was evaluated in an urban setting through various walking scenarios. The tests demonstrated promising results, with potential and broad application across populations with reduced autonomy.
