Despite the importance of attention in user performance, current methods for attention... (more)

Leveraging Active Learning and Conditional Mutual Information to Minimize Data Annotation in Human Activity Recognition

A difficulty in human activity recognition (HAR) with wearable sensors is the acquisition of large... (more)

EduSense: Practical Classroom Sensing at Scale

Providing university teachers with high-quality opportunities for professional development cannot happen without data about the classroom environment. Currently, the most effective mechanism is for an expert to observe one or more lectures and provide personalized formative feedback to the... (more)

To Mask or Not to Mask?: Balancing Privacy with Visual Confirmation Utility in Activity-Oriented Wearable Cameras

Activity-oriented cameras are increasingly being used to provide visual confirmation of specific hand-related activities in real-world settings. However, recent studies have shown that bystander privacy concerns limit participant willingness to wear a camera. Researchers have investigated different image obfuscation methods as an approach to... (more)

Mobile Gait Analysis Using Foot-Mounted UWB Sensors

We demonstrate a new foot-mounted sensor system for mobile gait analysis which is based on Ultra Wideband (UWB) technology. Our system is wireless,... (more)

Back to Real Pictures: A Cross-generational Understanding of Users' Mental Models of Photo Cloud Storage

Personal pictures storage is currently split between a myriad of physical and digital tools. Cloud photo storage and social networks are seeing increasing adoption, and are being recommended to families (especially older generations) as digital pictures solutions. The ubiquity of these platforms raises the question of whether the design of their... (more)

Prediction of Mood Instability with Passive Sensing

Mental health issues, which can be difficult to diagnose, are a growing concern worldwide. For... (more)

The Positive Impact of Push vs Pull Progress Feedback: A 6-week Activity Tracking Study in the Wild

Lack of physical activity has been shown to increase disease and reduce life expectancy. In response, mobile devices are increasingly being used to... (more)

ProspecFit: In Situ Evaluation of Digital Prospective Memory Training for Older Adults

Prospective Memory (PM), which involves remembering to perform intended actions, is the primary source of everyday memory lapses. While existing solutions mostly focus on supportive memory aids and reminders, it is also crucial to maintain PM functions and independent living for older adults. We present ProspecFit, which digitises implementation... (more)

TurnsMap: Enhancing Driving Safety at Intersections with Mobile Crowdsensing and Deep Learning

Left turns are known to be one of the most dangerous driving maneuvers.1 An effective way to mitigate this safety risk is to install a left-turn enforcement --- e.g., a protected left-turn signal or all-way stop signs --- at every turn that preserves a traffic phase exclusively for left turns. Although this protection scheme can significantly... (more)

LungTrack: Towards Contactless and Zero Dead-Zone Respiration Monitoring with Commodity RFIDs

Respiration rate sensing plays a critical role in elderly care and patient monitoring. The latest research has explored the possibility of employing Wi-Fi signals for respiration sensing without attaching a device to the target. A critical issue with these solutions includes that good monitoring performance could only be achieved at certain... (more)

ASSV: Handwritten Signature Verification Using Acoustic Signals

As one kind of biological characteristics of people, handwritten signature has been widely used in the banking industry, government and education. Verifying handwritten signatures manually causes too much human cost, and its high probability of errors can threaten the property safety and even society stability. Therefore, the need for an automatic... (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.
