Many people can author static web pages with HTML and CSS but find it hard or impossible to program persistent, interactive web applications. We show that for a broad class of CRUD (Create, Read, Update, Delete) applications, this gap can be bridged. Mavo extends the declarative syntax of HTML to describe Web applications that manage, store and transform data. Using Mavo, authors with basic HTML knowledge define complex data schemas implicitly as they design their HTML layout. They need only add a few attributes and expressions to their HTML elements to transform their static design into a persistent, data-driven web application whose data can be edited by direct manipulation of the content in the browser. We evaluated Mavo with 20 users who marked up static designs-some provided by us, some their own creation-to transform them into fully functional web applications. Even users with no programming experience were able to quickly craft Mavo applications.
Kinesthetic feedback requires linkage-based high-powered multi-dimensional manipulators, which are currently not possible to integrate with mobile devices. To overcome this challenge, we developed a novel system that ...

Number entry systems in medical devices such as infusion pumps are used to input drug doses that will be administered to patients. They are safety critical since if the drug dose is too high or too low, this may cause harm to patients. Previous work shows that number entry systems with the same hardware layout can have software that is implemented in different ways. This means that devices with the same hardware layout may lead to different results after the same keystrokes are pressed. Previous work also shows that choosing the best software implementation over the worst can reduce the likelihood of human error eight-fold in directional number entry systems. Determining whether a software implementation abides by the requirements is a time consuming task for regulatory bodies and hospital procurement departments. In this paper we show how software testing techniques can be used to classify various software implementations in order to determine whether the given number entry system satisfies specifications.

Natural language interfaces for visualizations have emerged as a promising new way of interacting with data and performing analytics. Many of these systems have fundamental limitations. Most return minimally interactive visualizations in response to queries and often require experts to perform modeling for a set of predicted user queries before the systems are effective. Eviza provides a natural language interface for an interactive query dialog with an existing visualization rather than starting from a blank sheet and asking closed-ended questions that return a single text answer or static visualization. The system employs a probabilistic grammar based approach with predefined rules that are dynamically updated based on the data from the visualization, as opposed to computationally intensive deep learning or knowledge based approaches. The result of an interaction is a change to the view (e.g., filtering, navigation, selection) providing graphical answers and ambiguity widgets to handle ambiguous queries and system defaults. There is also rich domain awareness of time, space, and quantitative reasoning built in, and linking into existing knowledge bases for additional semantics. Eviza also supports pragmatics and exploring multimodal interactions to help enhance the expressiveness of how users can ask questions about their data during the flow of visual analysis.
We present a technique for detecting gestures on the edge of an unmodified smartwatch. We demonstrate two exemplary gestures, i) Sidetap - tapping on any side and ii) Slingshot - pressing on the edge and then releasin...

Much of the language of computation is based on the idea that virtual experiences are, by definition, immaterial. On the other hand, in the context of mobile and ubiquitous computing, we have been reminded of the importance of the physical world, and many in HCI over the last decade have been intrigued by the possibilities of new interactive materials. In this talk, I will explore the range of ways that we might want to grapple with the materiality of information --- not just of information infrastructures, or of information-rich objects, but of digital information itself and particularly information representations. I will draw on research from anthropology, philosophy, and science studies to demonstrate how we might incorporate a sense of the material more deeply into the ways that we think about interaction with digital information.

Today's commercially available prosthetic limbs lack tactile sensation and feedback. Recent research in this domain focuses on sensor technologies designed to be directly embedded into future prostheses. We present a novel concept and prototype of a prosthetic-sensing wearable that offers a non-invasive, self-applicable and customizable approach for the sensory augmentation of present-day and future low to mid-range priced lower-limb prosthetics. From consultation with eight lower-limb amputees, we investigated the design space for prosthetic sensing wearables and developed novel interaction methods for dynamic, user-driven creation and mapping of sensing regions on the foot to wearable haptic feedback actuators. Based on a pilot-study with amputees, we assessed the utility of our design in scenarios brought up by the amputees and we summarize our findings to establish future directions for research into using smart textiles for the sensory enhancement of prosthetic limbs.

We explore the contextual details afforded by wearable devices to support multi-user, direct-touch interaction on electronic whiteboards in a way that-unlike previous work-can be fully consistent with natural bimanual-asymmetric interaction as set forth by Guiard. Our work offers the following key observation. While Guiard's framework has been widely applied in HCI, for bimanual interfaces where each hand interacts via direct touch, subtle limitations of multi-touch technologies-as well as limitations in conception and design-mean that the resulting interfaces often cannot fully adhere to Guiard's principles even if they want to. The interactions are fundamentally ambiguous because the system does not know which hand, left or right, contributes each touch. But by integrating additional context from wearable devices, our system can identify which user is touching, as well as distinguish what hand they use to do so. This enables our prototypes to respect lateral preference-the assignment of natural roles to each hand as advocated by Guiard-in a way that has not been articulated before.
