ARCADE proposes leveraging interactive and digital technologies to create context-aware workspaces to improve physical rehabilitation practices.
We investigate novel interfaces and interaction techniques for nonvisual word completion. We are particularly interested in quantifying the benefits and costs of such new solutions.
Braille 21 is an umbrella term for a series of research projects that aim to bring Braille to the 21st century. Our goal is to facilitate access to Braille in the new digital era.
In this project, we are creating the tools to characterize user performance in the wild and improve current everyday devices and interfaces.
This research leverages mobile and wearable technologies to improve classroom accessibility for Deaf and Hard of Hearing college students.
Although text-entry is an inherently visually demanding task, we are creating novel non-visual input methods to multiple form-factors: from tablets to smartwatches.
As touchscreens have evolved to provide multitouch capabilities, we are exploring new multi-point feedback solutions.
In this research work, we are investigating novel interactive applications that leverage the use of concurrent speech to improve users' experiences.
We aim to understand the overlap of problems faced by health and situational impaired users when using their mobile devices and design solutions for both user groups.
This project investigates how accurate tracking systems and engaging activities can be leveraged to provide effective evaluation procedures in physical rehabilitation.
Our goal is to thoroughly study mobile touchscreen interfaces, their characteristics and parameterizations, thus providing the tools for informed interface design.
Mobile device users are required to constantly learn to use new apps, features, and adapt to updates. For blind people, adaptingto a new interface requires additional time and effort. At the limit, and often so, devices and applications may become unusable without support from someone else. Using tutorials is a common approach to foster independent learning of new concepts and workflows. However, most tutorials available online are limited in scope, detail, or quickly become outdated. Also, they presume a degree of tech savviness that is not atthe reach of the common mobile device user. Our research explores the democratization of assistance by enabling non-technical people to create tutorials in their mobile phones for others. We report on the interaction and information needs of blind people when following ’amateur’ tutorials. Thus, providing insights into how to widen and improve the authoring and playthrough of these learning artifacts. We conducted a study where 12 blind users followed tutorials previously created by blind or sighted people. Our findings suggest that instructions authored by sighted andblind people are limited in different aspects, and that those limitations prevent effective learning of the task at hand. We identified the types of contents produced by authors and the information required by followers during playthrough, which often do not align. We provide insights on how to support both authoring and playthrough of nonvisual smartphone tutorials. There is an opportunity to design solutions that mediate authoring, combine contributions, adapt to user profile, react to context and are living artifacts capable of perpetual improvement.
In this preliminary study, we propose visual biofeedback techniques for representing compensatory movements that are commonly found in upper limb rehabilitation exercises. Here, visual biofeedback is represented by stick figures adorned with different graphical elements to highlight abnormal motor patterns. We explore 4 visual biofeedback techniques for analysing movements designed for neuromotor rehabilitation of the upper limb. Co-design sessions were conducted next to 5 rehabilitation professionals. The resulting visual designs were then evaluated by 3 other physiotherapists, each evaluated the visual biofeedback of two types of compensatory movements: arm elevation-flexion and cephalic tilt. Results indicate that although there is a preferred technique, participants suggested to design a novel representation that should incorporate features from different sources, thus designing a hybrid visual biofeedback technique.
