‘WanderSmart’ is an innovative design that distinguishes from the current anti-wandering devices. It aims to ease caregivers’ burden in dementia caregiving. Being a simple, universal design which costs HK$300 but provides a safe caregiving. ‘WanderSmart’ can be widely applied at home or institutional setting with high cost-effectiveness. The current device uses the Walkie Taklie to alert the caregiver and allows a distant supervision up to 2-5km via remote signals. When the elder tries to leave home/room, he/she will trigger the PIR sensor that transmits a signal to the Walkie Talkie through a mechanical relay and alert the caregiver with an easily noticeable tone. Caregivers at home will then have more freedom to engage in their own meaningful tasks such as cooking, going to washroom or even nearby market for shopping. It is simple, once the charger is plugged in and the switch is pressed, the device is ready to use.
