Handling conflicts of context-aware reminding system in sensorised home

Abstract

In this paper, we propose a context-aware reminding system to assist dementia elders for their daily activities. We particularly focus on the issue of conflict detecting and handling in the real-world reminding applications. We adopt a planning approach to describe the constraints of reminders, and transform the constraints into temporal constraint graph for reminder conflict detecting. In real-time reminder scheduling, we define three disruptive activities, and present a context-aware reminding strategy to handle the conflicts between pre-planned and disruptive activities. Finally, the system prototype is introduced.

Formal Analysis of Pervasive Computing Systems

“…It is also important to check if these services are sent properly. Some problems have been reported by domain experts such as conflicts of reminders [19]. These problems are especially common in multi-user systems.…”

An Integrated Service Platform for Pervasive Elderly Care

“…People with dementia perform their daily routines poorly, and often cannot conduct instrumental activities of daily living [27], such as preparing meals, and doing housework.…”

Assisted Living Services for Reminding and Prompting Activities of Daily Living: A Preliminary Case Study

“…In [10] Osmani et al presented an approach to provide reminders appropriate to current contexts including the location and in particular the activity inferred from sensors monitoring interactions with everyday objects. Du et al [11] adopted a planning approach to represent the constraints of reminders. The system is made aware of activity contexts and can handle conflicts between multiple reminders and between pre-planned and disruptive activities.…”
