Is More Always Better?: Discovering Incentivized mHealth Intervention Engagement Related to Health Behavior Trends

Behavioral medicine is devoting increasing attention to the topic of participant engagement and its role in effective mobile health (mHealth) behavioral interventions. Several definitions of the term "engagement" have been proposed and discussed, especially in the context of digital health behavioral interventions. We consider that engagement... (more)

SoundSignaling: Realtime, Stylistic Modification of a Personal Music Corpus for Information Delivery

Drawing inspiration from the notion of cognitive incongruence associated with Stroop's famous experiment, from musical principles, and from the observation that music consumption on an individual basis is becoming increasingly ubiquitous, we present the SoundSignaling system -- a software platform designed to make real-time, stylistically relevant...

Amateur: Augmented Reality Based Vehicle Navigation System

This paper presents Amateur, an augmented reality based vehicle navigation system using commodity smart phones. Amateur reads the navigation information from a digital map, matches it into live road condition video captured by smart phone, and directly annotates the navigation instructions on the video stream. The Amateur design entails two major... (more)

Revisitation in Urban Space vs. Online: A Comparison across POIs, Websites, and Smartphone Apps

We present the first large-scale analysis of POI revisitation patterns, which aims to model the periodic behavior in human mobility. We apply the revisitation analysis technique, which has previously been used to understand website revisitation, and smartphone app revisitations. We analyze a 1.5-year-long Foursquare check-in dataset with 266,909... (more)

Mobile Money: Understanding and Predicting its Adoption and Use in a Developing Economy

Access to financial institutions is difficult in developing economies and especially for the poor. However, the widespread adoption of mobile phones has enabled the development of mobile money systems that deliver financial services through the mobile phone network. Despite the success of mobile money, there is a lack of quantitative studies that... (more)

Performance Characterization of Deep Learning Models for Breathing-based Authentication on Resource-Constrained Devices

Providing secure access to smart devices such as smartphones, wearables and various other IoT... (more)

CrowdX: Enhancing Automatic Construction of Indoor Floorplan with Opportunistic Encounters

The lack of floorplan limits the spread of pervasive indoor location-based services. Existing crowdsourcing based approaches mostly rely on identifying, locating landmarks in the environment and utilizing the spatial relationship between the landmarks and traces for efficiently constructing fine-grained floorplan. However, these methods are always... (more)

Detecting Door Events Using a Smartphone via Active Sound Sensing

Event detection of indoor objects, including doors, has a wide variety of applications, including intruder detection, HVAC control, and surveillance... (more)

What is That in Your Hand?: Recognizing Grasped Objects via Forearm Electromyography Sensing

Knowing the object in hand can offer essential contextual information revealing a user's fine-grained activities. In this paper, we investigate the feasibility, accuracy, and robustness of recognizing the uninstrumented object in a user's hand by sensing and decoding her forearm muscular activities via off-the-shelf electromyography (EMG) sensors....

Painting an Apple with an Apple: A Tangible Tabletop Interface for Painting with Physical Objects

We introduce UnicrePaint, a digital painting system that allows the user to paint with physical objects by acquiring three parameters from the interacting object: the form, the color pattern and the contact pressure. The design of the system is motivated by a hypothesis that integrating direct input from physical objects with digital painting... (more)

Detecting Conversing Groups Using Social Dynamics from Wearable Acceleration: Group Size Awareness

In this paper, we propose a method for detecting conversing groups. More specifically, we detect pairwise F-formation membership using a single worn... (more)

Fingers and Angles: Exploring the Comfort of Touch Input on Smartwatches

Smartwatches present a unique touch input context: small, fixed to one wrist and approachable from a limited range of angles by the touching hand. Techniques to expand their input expressivity often involve variations in how a watch must be touched, such as with different fingers, poses or from specific angles. While objective performance with such... (more)


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.
