This paper presents a review of ubiquitous technologies developed and studied in the context of assistive living for people with neurodegenerative diseases (NDs). There are varieties of NDs in the medical literature but the ones which have captured the attention of researchers in Ubiquitous Computing (UbiComp) arena more than others are: Alzheimer’s Disease (AD), Parkinson Disease (PD), Huntington Disease (HD), Multiple Sclerosis (MS) and Amyotrophic Lateral Sclerosis (ALS). Therefore, we have followed this trend in reviewing the literature and searching for these common NDs as keywords in ACM Digital Library. Between 2004 and 2014 we have found 47 papers on AD, 20 papers on PD, two papers on HD, zero papers on MS and two papers on ALS where UbiComp has been employed for assisting people who live with diseases. Inertial sensors such as accelerometer, magnetometer and gyroscope and location sensors such as GPS are the most widely used sensors in assistive living for people with ND. These sensors allow researchers to not only extract limb movements and analyse and detect varieties of activities throughout the day but also to detect early symptoms of certain cognitive impairment diseases from day to day activities. Employing embedded sensors on smartphones to assist patients living with ND became prominent in research papers published in UbiComp arena from 2008 and the number has been growing ever since.
