Despite advancements with intelligence and connectivity in the workspace, productivity tools, such as to-do list applications, still, measure workers' performance by a binary state-completed, yet completed, and thus the number of tasks completed. Such quantitative measurements can often overlook human values and individual well-being. While concepts such as positive computing and digital well-being are on the rise in the HCI community, few systems have been proposed to efectively integrate holistic considerations for mental and emotional well-being into productivity tools. In this work, we depart from the classic task list management tool and explore the construction of well-being-centered to-do list software. We propose a task management system-TaskScape-, which allow users to have awareness on the following two aspects: (1) how they plan and complete tasks and (2) how they feel towards their work. With the proposed system, we will investigate if having holistic view on their tasks can facilitate refection on what they work on, how they stick to their plans, and how their tasks portfolio support their emotional well-being, nudging users to refect upon their work, planning performance, and their emotional values towards their work. In this poster, we share the design, development, and ongoing validation progress of TaskScape, which is aimed to nudge workers to holistically view work productivity, reminding users that work is more than just work but life.

user engagement in Virtual Reality (VR) games is crucial for creating immersive and captivating gaming experiences that meet the expectations of players. However, understanding and measuring these levels in VR games presents a challenge for game designers, as current methods, such as self-reports, may be limited in capturing the full extent of user engagement. Additionally, approaches based on biological signals to measure engagement in VR games present complications and challenges, including signal complexity, interpretation difficulties, and ethical concerns. This study explores body movements, as a novel approach to measure user engagement in VR gaming. We employ E4, emteqPRO, and off-the-shelf IMUs to measure the body movements from diverse participants engaged in multiple VR games. Further, we examine the simultaneous occurrence of player motivation and physiological responses to explore potential associations with body movements. Our findings suggest that body movements hold promise as a reliable and objective indicator of user engagement, offering game designers valuable insights on generating more engaging and immersive experiences.

The lack of diverse UI element representations in publicly available datasets hinders the scalability of sketch-based interactive mobile search. This paper introduces D2S2, a novel approach that addresses this limitation via drag-and-drop mobile screen search, accommodating visual and text-based queries. D2S2 searches 58k Rico screens for relevant UI examples based on UI element attributes, including type, position, shape, and text. In an evaluation with 10 novice software developers D2S2 successfully retrieves target screens within the top-20 search results in 15/19 attempts within a minute. The tool offers interactive and iterative search, updating its search results each time the user modifies the search query. Interested users can freely access D2S2 (http://***/D2S2), build on D2S2 or replicate results via D2S2's open-source implementation (https://***/toni-tang/D2S2), or watch D2S2's video demonstration (https://***/fdoYiw8lAn0).

A common method of generating a garment pattern is by draping fabric on a 3D form. Many apparel designers prefer this tangible process rather than the more abstract process of drafting patterns in 2D using CAD software, but the visualization benefits of 3D rendering remain important to product development. Currently, draped patterns must be manually digitized to transfer the shape to the CAD environment, a cumbersome process. Here, we explore augmenting the fabric used to drape patterns with e-textile components, such that pinning the fabric to the form directly digitizes the pattern shape. The e-textile interface uses a keypad matrix approach with rows and columns on opposite sides of the fabric. Passing a metallic pin through a row/column intersection creates a circuit connection that a microcontroller reads and maps to a 2D spatial layout on the screen. The proof-of-concept device developed here is a first step toward an automatic digitizing system that allows designers to preserve manual skills and processes while integrating more efficiently with digital systems.

Born from physical activities, dance carries beyond mere body movement. Choreographers interact with audiences' perceptions through the kinaesthetics, creativity, and expressivity of whole-body performance, inviting them to construct experience, emotion, culture, and meaning together. Computational choreography support can bring endless possibilities into this one of the most experiential and creative artistic forms. While various interactive and motion technologies have been developed and adopted to support creative choreographic processes, little work has been done in exploring incorporating machine learning in a choreographic system, and few remote dance teaching systems in particular have been suggested. In this exploratory work, we proposed Echofluid-a novel AI-based choreographic learning and support system that allows student dancers to compose their own AI models for learning, evaluation, exploration, and creation. In this poster, we present the design, development and ongoing validation process of Echofluid, and discuss the possibilities of applying machine learning in collaborative art and dance as well as the opportunities of augmenting interactive experiences between the performers and audiences with emerging technologies.

Gesture-based recognition systems are susceptible to input recognition errors and user errors, both of which negatively afect user experiences and can be frustrating to correct. Prior work has suggested that user gaze patterns following an input event could be used to detect input recognition errors and subsequently improve interaction. However, to be useful, error detection systems would need to detect various types of high-cost errors. Furthermore, to build a reliable detection model for errors, gaze behaviour following these errors must be manifested consistently across diferent tasks. Using data analysis and machine learning models, this research examined gaze dynamics following input events in virtual reality (VR). Across three distinct point-and-select tasks, we found diferences in user gaze patterns following three input events: correctly recognized input actions, input recognition errors, and user errors. These diferences were consistent across tasks, selection versus deselection actions, and naturally occurring versus experimentally injected input recognition errors. A multi-class deep neural network successfully discriminated between these three input events using only gaze dynamics, achieving an AUC-ROC-OVR score of 0.78. Together, these results demonstrate the utility of gaze in detecting interaction errors and have implications for the design of intelligent systems that can assist with adaptive error recovery.

Various reasons exist why humans desire to magnify portions of our visually perceived surroundings, e.g., because they are too far away or too small to see with the naked eye. Different technologies are used to facilitate magnification, from telescopes to microscopes using monocular or binocular designs. In particular, modern digital cameras capable of optical and/or digital zoom are very flexible as their high-resolution imagery can be presented to users in real-time with displays and interfaces allowing control over the magnification. In this paper, we present a novel design space of intuitive augmented reality (AR) magnifications where an AR head-mounted display is used for the presentation of real-time magnified camera imagery. We present a user study evaluating and comparing different visual presentation methods and AR interaction techniques. Our results show different advantages for unimanual, bimanual, and situated AR magnification window interfaces, near versus far vergence distances for the image presentation, and five different user interfaces for specifying the scaling factor of the imagery.

Reliable statistical analyses are critical for making scientific discoveries, guiding policy, and informing decisions. To author reliable statistical analyses, integrating knowledge about the domain, data, statistics, and programming is necessary. However, this is an unrealistic expectation for many analysts who may possess domain expertise but lack statistical or programming expertise, including many researchers, policy makers, and other data scientists. How can our statistical software help these analysts? To address this need, we first probed into the cognitive and operational processes involved in authoring statistical analyses and developed the theory of hypothesis formalization. Authoring statistical analyses is a dual-search process that requires grappling with assumptions about conceptual relationships and iterating on statistical model implementations. This led to our key insight: statistical software needs to help analysts translate what they know about their domain and data into statistical modeling programs. To do so, statistical software must provide programming interfaces and interaction models that allow statistical non-experts to express their analysis goals accurately and reflect on their domain knowledge and data. Thus far, we have developed two such systems that embody this insight: Tea and Tisane. Ongoing work on rTisane explores new semantics for more accurately eliciting analysis intent and conceptual knowledge. Additionally, we are planning a summative evaluation of rTisane to assess our hypothesis that this new way of authoring statistical analyses makes domain experts more aware of their implicit assumptions, able to author and understand nuanced statistical models that answer their research questions, and avoid previous analysis mistakes.

Forward biomechanical simulation in HCI holds great promise as a tool for evaluation, design, and engineering of user interfaces. Although reinforcement learning (RL) has been used to simulate biomechanics in interaction, prior work has relied on unrealistic assumptions about the control problem involved, which limits the plausibility of emerging policies. These assumptions include direct torque actuation as opposed to muscle-based control;direct, privileged access to the external environment, instead of imperfect sensory observations;and lack of interaction with physical input devices. In this paper, we present a new approach for learning muscle-actuated control policies based on perceptual feedback in interaction tasks with physical input devices. This allows modelling of more realistic interaction tasks with cognitively plausible visuomotor control. We show that our simulated user model successfully learns a variety of tasks representing different interaction methods, and that the model exhibits characteristic movement regularities observed in studies of pointing. We provide an open-source implementation which can be extended with further biomechanical models, perception models, and interactive environments.

Engineering the Transition of Interactive Collaborative software from Cloud Computing to Edge Computing

The "software as a Service"(SaaS) model of cloud computing popularized online multiuser collaborative software. Two famous examples of this class of software are Office 365 from Microsoft and Google Workspace. Cloud technology removes the need to install and update the software on end users' computers and provides the necessary underlying infrastructure for online collaboration. However, to provide a good end-user experience, cloud services require an infrastructure able to scale up to the task and allow low-latency interactions with a variety of users worldwide. This is a limiting factor for actors that do not possess such infrastructure. Unlike cloud computing which forgets the computational and interactional capabilities of end users' devices, the edge computing paradigm promises to exploit them as much as possible. To investigate the potential of edge computing over cloud computing, this paper presents a method for engineering interactive collaborative software supported by edge devices for the replacement of cloud computing resources. Our method is able to handle user interface aspects such as connection, execution, migration, and disconnection differently depending on the available technology. We exemplify our approach by developing a distributed Pictionary game deployed in two scenarios: A nonshared scenario where each participant interacts only with their own device and a shared scenario where participants also share a common device, including a TV. After a theoretical comparative study of edge vs. cloud computing, an experiment compares the two implementations to determine their effect on the end user's perceived experience and latency vs. real latency. © 2022 acm.
