Caregivers can use sensor doorbells with recording function or sensor cushions equipped with a buzzer, which will emit a sound or a verbal message when the elder approaches the door or leaves the seat, so as to remind the elder not to leave and the caregiver can know the location of the elder instantly.
The caregiver can record messages that can effectively reduce the anxiety of the elderly.
For example, if the elderly often miss their daughters and go out to look for them, they can record their daughters' comforting words to the elderly: “I will come on Sunday, don't worry, please stay home and wait for me to come back”; if the elderly often have to go out for shopping, they can record the reminder: “I have done the shopping today, please take a look at the items in the kitchen”, so that the caregiver can show the elderly what they have already purchased today.
