1.1 Introduction to Ubicomp for Home Healthcare

The concept of ubiquitous computing (ubicomp), coined by Mark Weiser in 1991, focused on having computation in any regular “smart” object (Weiser, 1991). The key idea of ubicomp (aka pervasive computing (Satyanarayanan, 2001)) is the use of embedded technology everywhere and disappearing in background, i.e. not requiring any extra cognitive effort to use such “augmented” objects. Later, in 1999, Kevin Ashton devised the term Internet of things (IoT), which envisioned the interconnection of any physical object through the Internet (Ashton, 2009). Such concept opens the door for sensing massive amounts of data into cloud databases (cf. big data) and exposing general environment contexts to a multitude of analytic and automation tools. The ability to reasoning about human context environments allows also the orchestration of such environments by pushing back actuation over physical objects. Both ubicomp and IoT propose basically similar seminal ideas and are considered synonyms of physical computing.

It is clear that ubicomp or IoT technologies can tackle the growing need for ambient assisted living (AAL) environments, which are mainly driven by the aging of the world population. This phenomenon is usually associated with chronic or disabling diseases, such as memory loss, disorientation and loss hazards, polymedication coping, difficulties in adhering to clinical treatments, unintended erroneous medication intake, adherence to therapeutic exercises, etc. These problems pose several difficulties on executing even simple daily life tasks. However, some of these issues may be addressed and mitigated by the integration of ubicomp home support systems specially developed and tailored for the elderly or those with special needs, thus promoting and allowing outpatient and home healthcare. Therefore, this work advocates that there are several key capabilities that must be provided so that AAL environments may be automated from independently developed commercial off‐the‐shelf (COTS) systems. These key capabilities are as follows:

• Processing and sensing issues: Ubicomp systems sense and explore any knowledge about the context they operate in. The context refers to information that may be used to characterize the situation of an entity (Abowd et al., 1999) and may refer to user, physical, computational, and time context (Chen and Kotz, 2000). Sensors are fundamental to collect data from any environment; however, raw sensor data most of the times is not enough to provide useful high level context information. Therefore, raw data must be processed into more high level information constructs. For example, use the signal of Bluetooth Low Energy (BLE) beacons to estimate distances and calculate the location of devices; use a three‐axis accelerometer data time series to estimate the posture of a person (e.g. fall, run, walk, stand, lay, sit).
• Integration and management issues: The deployment of COTS systems in the same AAL household has two fundamental concerns: (i) The standard interconnection and orchestration of devices for enabling seamless interactions and automation. The integration of COTS systems could be achieved through the use of local or edge middleware frameworks such as openHAB or Simple Network Management Protocol (SNMP)‐like tools. Another important trend is the integration through cloud services that glue together heterogeneous deployed systems. (ii) The secure or safe integration of COTS systems that are developed by independent vendors without integration concerns, thus not planned to be deployed together. These systems must coexist in the same ecosystem without causing crossed malfunctions. For example, a drug dispenser (DD) periodically issuing a sound alarm until the user takes a prescribed medicine could suffer a functional interference from an entertainment system that simultaneously could be playing a movie or TV series. When two or more systems compete for a shared medium (e.g. user attention), that may cause a behavior interference (e.g. prevent user from taking medication).
• Communication and coordination issues: Home healthcare COTS systems play an important role in the deployment of AAL smart spaces. However, it is important to guarantee agile and affordable deployment mechanisms without preinstalled communication infrastructures. Wireless mesh technologies are therefore fundamental to enable the growth and widespread of such ubiquitous systems. Most of smart spaces use body and environmental sensor motes deployed together without the need for fixed infrastructures. These modules communicate through heterogeneous wireless technologies, thus typically requiring bridging gateways equipped with multiple shields [e.g. ZigBee, Bluetooth (BT), Wi‐Fi, General Packet Radio Service (GPRS)], thus enabling simple and adaptable wireless topologies. These agile solutions allow easy data collection and storage for further analytical treatment and consultation by healthcare providers and also control interactions and trigger real‐time alerts in dangerous situations.
• Intelligence and reasoning issues: The representation of context information is fundamental in AAL systems. It is necessary to use knowledge representation models and tools that enable to reason about the premises and conditions about the user and its surroundings. Such tools may use typically deductive or inductive processes. This section proposes the use and combination of both types of reasoning. The former, deductive reasoning, uses the Semantic Web Rule Language (SWRL) that combines OWL and Rule Markup Language (RuleML) to allow the definition of Horn‐like rules. These rules specify a set of state conditions related by boolean operators that will allow the inference of other states or terms. The latter, inductive reasoning, uses machine learning (ML) algorithms that typically capture/learn patterns on sets of observations (training sets) and then generalize those patterns to classify new observations.
  The remaining sections will revisit each of these key research issues on separate sections. For every topic, the respective section details one or two example project outcomes related with the research solutions typically applied to home healthcare use cases. Section 1.2 addresses the aspects related with processing raw data sensor signals to ...
