A smart reminder system for complex human activities

A significant number of elders live with memory impairment issues, as a result of the normal aging process. Therefore various kinds of supporting systems have been developed to help the elders, who have mild memory problems. In this paper we propose a Smart Reminder System for reminding forgotten complex activities, in home environment. Subjected complex activities are the activities, which should be completed as originally intended, after they are initiated. Due to strong relationship among initiation and conclusion activities, those activities are called as “Coupling Activities” in this paper. Reminders for forgotten Coupling Activities are predicted according to the user´s current behaviour, current location and past activity patterns. Therefore wearable sensors are used to gather required data for identifying user´s context. A reason for forgetting also is predicted with the reminder. Reminders are predicted with minimum supervision of the user, as the system learns the user´s dynamic behaviour by itself. Proposed Smart Reminder System could achieve 80% average accuracy rate for reminder prediction in a system evaluation, which was done using four subjects.
