The use of Augmented Reality (AR) systems has been shown to be beneficial in guiding users through structured tasks when compared to traditional 2D instructions. In this work, we begin to examine the potential of such systems for home improvement tasks, which present some specific challenges (e.g., operating at both ...

Collecting a sufficient amount of 3D training data for autonomous vehicles to handle rare, but critical, traffic events (e.g., collisions) may take decades of deployment. Abundant video data of such events from municipal traffic cameras and video sharing sites (e.g., YouTube) could provide a potential alternative, but generating realistic training ...

While having a step-by-step breakdown for a task-an action plan-helps people complete tasks, prior work has shown that people prefer not to make action plans for their own tasks. Getting planning support from others could be beneficial, but it is limited by how much domain knowledge people have about the ...

Real-time collaboration between a requester and crowd workers expands the scope of tasks that crowdsourcing can be used for by letting requesters and crowd workers interactively create various artifacts (e.g., a sketch prototype, writing, or program code). In such systems, it is increasingly common to allow requesters to verbally describe ...

Voice interfaces such as in-home and mobile digital assistants, mobile screen readers, and chatbots are tools that can support communication, collaboration, and information seeking, and are becoming increasingly commonplace. Because they don't require the motor skills needed for text input through a keyboard, the barriers of entry and use for ...

Many web pages developed today require navigation by visual interaction-seeing, hovering, pointing, clicking, and dragging with the mouse over dynamic page content. These forms of interaction are increasingly popular as developer trends have moved from static, logically structured pages to dynamic, interactive pages. However, they are also often inaccessible to ...

Mobile, wearable, and other ubiquitous computing devices are increasingly creating a context in which conventional keyboard and screen-based inputs are being replaced in favor of more natural speech-based interactions. Digital personal assistants use speech to control a wide range of functionality, from environmental controls to information access. However, many deaf ...

Real-time crowdsourcing has made it possible to solve problems that are beyond the scope of artificial intelligence (AI) within a matter of seconds, rather than hours or days with traditional crowdsourcing techniques. While this has led to an increase in the potential application domains of crowdsourcing and human computation, problems ...

Digital educational resources could enable the use of randomized experiments to answer pedagogical questions that instructors care about, taking academic research out of the laboratory and into the classroom. We take an instructor-centered approach to designing tools for experimentation that lower the barriers for instructors to conduct experiments. We explore ...

Having a step-by-step list of instructions for completing a task - a plan - enables people to make progress on challenging tasks, but making plans for tasks is a tedious job. Asking crowdworkers to make plans for others' tasks only works for independent (context-free) tasks, and asking people who have ...

Crowdsourcing is a common means of collecting image segmentation training data for use in a variety of computer vision applications. However, designing accurate crowd-powered image segmentation systems is challenging because defining object boundaries in an image requires significant fine motor skills and hand-eye coordination, which makes these tasks error-prone. Typically, ...

Low-fidelity prototyping at the early stages of user interface (UI) design can help designers and system builders quickly explore their ideas. However, interactive behaviors in such prototypes are often replaced by textual descriptions because it usually takes even professionals hours or days to create animated interactive elements due to the ...

Email is more than just a communication medium. Email serves as an external memory for people---it contains our reservation numbers, meeting details, phone numbers, and more. Often, people need access to this information while on the go, which is cumbersome from mobile devices with limited I/O bandwidth. In this paper, ...

Quickly converting speech to text allows deaf and hard of hearing people to interactively follow along with live speech. Doing so reliably requires a combination of perception, understanding, and speed that neither humans nor machines possess alone.

Software development is a complex task with inherently interdependent sub-components. Prior work on crowdsourcing software engineering has addressed this problem by performing an a priori decomposition of the task into well-defined microtasks that individual crowd workers can complete independently. Alternatively, ad hoc teams of experts recruited from online crowds can ...

Crowdsourcing and human computation are useful in a number of real-world applications. Crowds generate large data sets useful for natural language processing and computer vision; they work together to formulate intelligent responses far beyond what we can automate; and they power intelligent interactive systems currently impossible with automated approaches alone. ...
