mORAL: An mHealth Model for Inferring Oral Hygiene Behaviors in-the-wild Using Wrist-worn Inertial Sensors

We address the open problem of reliably detecting oral health behaviors passively from wrist-worn inertial sensors. We present our model named mORAL (pronounced em oral) for detecting brushing and flossing behaviors, without the use of instrumented toothbrushes so that the model is applicable to brushing with still prevalent manual toothbrushes. We... (more)

Deep Multi-Task Learning Based Urban Air Quality Index Modelling

Obtaining comprehensive air quality information can help protect human health from air pollution. Existing spatially fine-grained estimation methods... (more)

Your Table Can Be an Input Panel: Acoustic-based Device-Free Interaction Recognition

This paper explores the possibility of extending the input and interactions beyond the small screen of the mobile device onto ad hoc adjacent surfaces, e.g., a wooden tabletop with acoustic signals. While the existing finger tracking approaches employ the active acoustic signal with a fixed frequency, our proposed system Ipanel employs the acoustic... (more)

CAP: Context-aware App Usage Prediction with Heterogeneous Graph Embedding

Context-aware mobile application (App) usage prediction benefits a variety of applications such as precise bandwidth allocation, App launch acceleration, etc. Prior works have explored this topic through individual data profiles and contextual information. However, it is still a challenging problem because of the following three aspects: i. App... (more)

Understanding Parents' Perspectives on Mealtime Technology

For young children, family meals are an enjoyable and developmentally useful part of daily life. Although prior work has shown that ubiquitous... (more)

ICT: In-field Calibration Transfer for Air Quality Sensor Deployments

Recent years have witnessed a growing interest in urban air pollution monitoring, where hundreds of low-cost air quality sensors are deployed city-wide. To guarantee data accuracy and consistency, these sensors need periodic calibration after deployment. Since access to ground truth references is often limited in large-scale deployments, it is...

Identifying and Planning for Individualized Change: Patient-Provider Collaboration Using Lightweight Food Diaries in Healthy Eating and Irritable Bowel Syndrome

Identifying and planning strategies that support a healthy lifestyle or manage a chronic disease often require patient-provider collaboration. For... (more)

Modeling Biobehavioral Rhythms with Passive Sensing in the Wild: A Case Study to Predict Readmission Risk after Pancreatic Surgery

Biobehavioral rhythms are associated with numerous health and life outcomes. We study the feasibility of detecting rhythms in data that is passively... (more)

Evaluating the Impact of Technology Assisted Hotspot Policing on Situational Awareness and Task-Load

Everyday field work of a police officer requires the perception, filtering and understanding of... (more)

Perils of Zero-Interaction Security in the Internet of Things

The Internet of Things (IoT) demands authentication systems which can provide both security and usability. Recent research utilizes the rich sensing... (more)

Privacy-preserving Cross-domain Location Recommendation

Cross-domain recommendation is a typical solution for data sparsity and cold start issue in the field of location recommendation. Specifically, data... (more)

Towards Reliable, Automated General Movement Assessment for Perinatal Stroke Screening in Infants Using Wearable Accelerometers

Perinatal stroke (PS) is a serious condition that, if undetected and thus untreated, often leads to... (more)

NEWS

Proceedings of the ACM on Interactive, Mobile, Wearable and Ubiquitous Technologies (IMWUT) is a premier journal for research relevant to the post-PC era. Computing technology is becoming increasingly pervasive; embedded throughout the environment as well as in mobile devices, wearables, and the Internet of Things. This is leading to a transformative change in the utility that technology can provide to users and societies, and how people relate to technology. IMWUT covers a broad range of topics relevant to this change, such as mobile systems, wearable technologies, and intelligent environments. The scope includes research contributions in systems and infrastructures, new hardware and sensing techniques, and studies of user experiences and societal impact. IMWUT also welcomes contributions on new methodologies and tools, theories and models, as well as visionary and survey papers that help advance the field.
