Submitty is an open-source course management platform for assignment submission with automated testing and grading, immediate feedback with an option for resubmission, and manual grading from course instructors and TAs. We have added an integrated discussion forum to the Submitty environment, which enables the students to communicate with their peers and have a public dialogue with the teaching staff outside of the classroom. Compared to a collection of closed-source external applications, our single-system login for distribution of course materials, assignment submission, and discussion forum participation is more convenient and accessible for students and simplifies administrative tasks. Students use the forum to ask questions about course logistics, homework help, exam review problems, and Submitty-related questions. The forum supports image and code segment posts, which facilitates targeted debugging help and sharing of additional reference material. An instructor-moderated forum is especially helpful in larger classes where students can feel it is otherwise difficult to get their questions answered. Every thread is tagged with course-specific categories and we provide full-text search of the forum. The forum becomes a curated collection of relevant frequently asked questions, which reduces the number of duplicate questions that must be answered by the staff. The forum includes customizable system and email notifications for important events such as: instructor announcement, assignment posted, team invitation, forum question answered, grades released, etc. Our current work focuses on private channels to facilitate team assignments (which can be monitored for participation by staff) and a grading interface for discussion-based assignments within the forum.
Model-based methodologies, supported by automatic generation, have been proposed as a solution to reduce software development costs. In the case of interactive computing systems specific challenges arise. On the one h...

We present PhyShare, a new haptic userinterface based on actuated robots. Virtual reality has recently been gaining wide adoption, and an effective haptic feedback in these scenarios can strongly support user's sensory in bridging virtual and physical world. Since participants do not directly observe these robotic proxies, we investigate the multiple mappings between physical robots and virtual proxies that can utilize the resources needed to provide a well rounded VR experience. PhyShare bots can act either as directly touchable objects or invisible carriers of physical objects, depending on different scenarios. They also support distributed collaboration, allowing remotely located VR collaborators to share the same physical feedback.

The Internet of Things (IoT) promises to revolutionize the way people interact with their environment and the objects within it by creating a ubiquitous network of physical devices. However, current advancement in IoT has been heavily targeted towards creating battery -powered electronics. There remains a huge gap between the collection of smart devices integrated into the IoT and the massive number of everyday physical objects. The goal of my research is to bridge this gap in the current IoT framework to enable novel sensing and interactive applications with daily objects.

Voice assistant technology has expanded the design space for voice-activated consumer products and audio-centric user experience. To navigate this emerging design space, Speech Synthesis Markup Language (SSML) provides a standard to characterize synthetic speech based on parametric control of the prosody elements, i.e. pitch, rate, volume, contour, range, and duration. However, the existing voice assistants utilizing Text-to-Speech (TTS) lack expressiveness. The need of a new production workflow for more efficient and emotional audio content using TTS is discussed. A prototype that allows a user to produce TTS-based content in any emotional tone using voice input is presented. To evaluate the new workflow enabled by the prototype, an initial comparative study is conducted against the parametric approach. Preliminary quantitative and qualitative results suggest the new workflow is more efficient based on time to complete tasks and number of design iterations, while maintaining the same level of user preferred production quality.

This paper proposes a new approach to enhancing interaction with general applications on smartphones. Physical objects held on back surface of the smartphone, which can be captured by the rear camera with a mirror, work as input devices or controllers. It does not require any additional electronic devices but offers tactile feedback. The occlusion problem does not occur when using smartphone's back side, in terms of both display and camera viewing. We implemented on an Android smartphone and confirmed that it provides richer interaction and low latency (100 ms).

Mobile technologies that drive just-in-time ecological momentary assessments and interventions provide an unprecedented view into user behaviors and opportunities to manage chronic conditions. The success of these methods rely on engaging the user at the appropriate moment, so as to maximize questionnaire and task completion rates. However, mobile operating systems provide little support to precisely specify the contextual conditions in which to notify and engage the user, and study designers often lack the expertise to build context-aware software themselves. To address this problem, we have developed Emu, a framework that eases the development of context-aware study applications by providing a concise and powerful interface for specifying temporal- and contextual-constraints for task notifications. In this paper we present the design of the Emu API and demonstrate its use in capturing a range of scenarios common to smartphone-based study applications.

We present CritiqueKit, a mixed-initiative machine-learning system that helps students give better feedback to peers by reusing prior feedback, reducing it to be useful in a general context, and retraining the system about what is useful in real time. CritiqueKit exploits the fact that novices often make similar errors, leading reviewers to reuse the same feedback on many different submissions. It takes advantage of all prior feedback, and classifies feedback as the reviewer types it. CritiqueKit continually updates the corpus of feedback with new comments that are added, and it guides reviewers to improve their feedback, and thus the entire corpus, over time.

Designing a VR content is a challenging task due to the complexity of the analysis of a user's experience. We propose a tool allowing a reviewer to record a user's movements when consuming a VR content, and to playback this experience. During the playback, the reviewer can visualize in real-time the visible objects to the user (within the field of view) or the interactive ones (within the workspace). Besides, the field of view and workspace of numerous devices can be simulated in order to predict how the content would fit. In the demonstration, a user is first invited to experience a VR scene. Then the recorded experience can be played back from a reviewer's point of view.
