| Indoor Localization: A Cost-Effectiveness vs. Accuracy StudyRecognizing the occupants' movement and locations within a home is a basic functionality, underlying a variety of smart-home services, including energy management, ambient-environment control, and assistive-living services for seniors and people with disabilities. The outdoor-localization variant of the problem is effectively addressed with the use of GPS; however, GPS does not work well inside buildings, which makes the indoor-positioning problem a very active research topic. In this paper, we report on a study of the indoor-localization problem, relying on easy-to-deploy, inexpensive, BLE-enabled stickers and beacons and WiFi access points.6.2 COG-ASSESS University of Alberta | Scientific Excellence - Advancing Knowledge | 2017-06-15 | |

| Sensor Design, Placement, and Data Fusion in the SmartCondoWe discuss the design and implementation of the SmartCondo sensor sub-system. We review the accumulated experience of integrating a system of heterogeneous sensors and protocols to provide essential services to an indoor localization and activity recognition system. Early design constraints included the need for passive non-intrusive monitoring. This led to a coverage-oriented deployment methodology and corresponding optimization problems. We will comment on the challenges that real deployments brought, beyond what was anticipated during the design phase. We discuss how the subsequent integration of multiple sensing modalities and the "black box" interaction with off-the-shelf systems, such as Estimotes, led to a particular sensor fusion methodology. It also demonstrated that the synchronization across heterogeneous sensor systems is a crucial factor to accuracy. Finally, we will comment on the potential of integrating sensors in the building construction process, rather than installing them as retrofits, and what kinds of opportunities for energy harvesting exist that could satisfy the energy needs of the sensors. 6.2 COG-ASSESS University of Alberta | Scientific Excellence - Leadership | 2017-12-18 | |

| Smart homes and home health monitoring technologies for older adults: A systematic reviewBACKGROUND: Around the world, populations are aging and there is a growing concern about ways that older adults can maintain their health and well-being while living in their homes. OBJECTIVES: The aim of this paper was to conduct a systematic literature review to determine: (1) the levels of technology readiness among older adults and, (2) evidence for smart homes and home-based health-monitoring technologies that support aging in place for older adults who have complex needs. RESULTS: We identified and analyzed 48 of 1863 relevant papers. Our analyses found that: (1) technology-readiness level for smart homes and home health monitoring technologies is low; (2) the highest level of evidence is 1b (i.e., one randomized controlled trial with a PEDro score >/=6); smart homes and home health monitoring technologies are used to monitor activities of daily living, cognitive decline and mental health, and heart conditions in older adults with complex needs; (3) there is no evidence that smart homes and home health monitoring technologies help address disability prediction and health-related quality of life, or fall prevention; and (4) there is conflicting evidence that smart homes and home health monitoring technologies help address chronic obstructive pulmonary disease. CONCLUSIONS: The level of technology readiness for smart homes and home health monitoring technologies is still low. The highest level of evidence found was in a study that supported home health technologies for use in monitoring activities of daily living, cognitive decline, mental health, and heart conditions in older adults with complex needs.6.1 MEN-ASSESS, 6.2 COG-ASSESS University of Alberta | Scientific Excellence - Advancing Knowledge | 2016-01-13 | |

| Simulation-Based Deployment Configuration of Smart Indoor SpacesEvaluating Wireless Sensor Network (WSN) deployment scenarios for sensor-driven applications is a tedious and labour-intensive task. To mitigate the cost involved with comparatively evaluating alternative deployments, we present an integrated methodology that enables the modeling, simulation, and evaluation of alternative candidate WSN deployments, as well as, the fine-tuning of the corresponding sensor--driven applications. Based on our previous experience on indoor occupant localization and activity recognition, we illustrate our methodology by applying it to the task of deploying an ambient-intelligence application. We explain how our methodology models the real-world environment and the candidate WSN deployment, simulates the occupants' activities and the WSN run-time behavior, and evaluates, through a variety of metrics, the effectiveness of the application under different deployment configurations. We demonstrate our methodology on two real-world localization application scenarios corresponding to two, drastically different, spaces.6.2 COG-ASSESS University of Alberta | Scientific Excellence - Advancing Knowledge | 2019-04-01 | |
