Humans coordinate teamwork by conveying intent through social cues, such as gestures and gaze behaviors. However, these methods may not be possible for appearance-constrained robots that lack anthropomorphic or zoomorphic features, aerial robots. We explore a new design space communicating robot motion investigating how augmented reality (AR) might mediate human-robot interactions. develop series of explicit implicit designs visually signaling using AR, which we evaluate in user study. found...

In recent years, the conceptualization of social support in literature has become increasingly sophisticated, facilitating consideration more complex theories. Researchers no longer consider mere availability ties, but look instead at flow specific resources through a network. This article discusses how network been defined context support. Research is reviewed, indicating characteristics individual tie (e.g., strength, proximity, frequency contact, similarity) are related to provision Also...

Robot teleoperation can be a challenging task, often requiring great deal of user training and expertise, especially for platforms with high degrees-of-freedom (e.g., industrial manipulators aerial robots). Users struggle to synthesize information robots collect camera stream) contextual knowledge how the robot is moving in environment. We explore advances augmented reality (AR) technologies are creating new design space mediating by enabling novel forms intuitive, visual feedback. prototype...

Teleoperation remains a dominant control paradigm for human interaction with robotic systems. However, teleoperation can be quite challenging, especially novice users. Even experienced users may face difficulties or inefficiencies when operating robot unfamiliar and/or complex dynamics, such as industrial manipulators aerial robots, forces to focus on low-level aspects of control, rather than higher level goals regarding task completion, data analysis, and problem solving. We explore how...

Augmented reality technologies allow people to view and interact with virtual objects that appear alongside physical in the real world. For augmented applications be effective, users must able accurately perceive intended world location of objects. However, when creating applications, developers are faced a variety design decisions may affect user perceptions regarding depth In this paper, we conducted two experiments using perceptual matching task understand how shading, cast shadows,...

Recent criticisms of large‐scale summative assessments have claimed that the are biased against historically excluded groups because assessments' lack cultural representation. Accompanying these is a call for more culturally responsive assessments—assessments take into account background characteristics students; their beliefs, values, and ethics; lived experiences; everything affects how they learn behave communicate. In this paper, we present provisional principles, based on review...

Abstract Although children over eight years of age appear to view others in dispositional terms, findings for kindergarten are mixed. Few studies have examined thinking younger than kindergarteners. The present addressed two questions about trait conceptions 4‐ and 5‐year‐old preschoolers'. (1). Do this use past behaviors predict future behavior si (2) they show evidence global evaluative thinking, such that generalize information one domain make predictions other domains'? Three...

This paper presents estimates for water consumption and steam generation within U.S. manufacturing industries. These were developed through the integration of detailed, industry-level fuel use operation data with an engineering-based system model. The results indicate that industrial systems consume approximately 3780 TBTU/yr (3.98 × 10(9) GJ/yr) to generate estimated 2.9 trillion lb/yr (1.3 kg/yr) steam. Since a good portion this is injected directly into plant processes, vented, leaked, or...

In this work, we explore how advances in augmented reality technologies are creating a new design space for long-distance telepresence communication through virtual avatars. Studies have shown that the relative size of speaker has significant impact on many aspects human including perceived dominance and persuasiveness. Our system synchronizes body pose remote user with realistic, avatar visible to local wearing an head-mounted display. We conducted two-by-two (relative size: equivalent vs....

Abstract This article is adapted from the 2024 NCME Presidential Address. It reflects a personal journey to challenge traditional views of measurement. Considering alternative viewpoints with an open mind led several solutions perplexing problems at time. The discusses culture‐boundedness measurement and need take that into consideration when designing tests.

In this study we examined variations of the nonequivalent groups equating design for tests containing both multiple‐choice (MC) and constructed‐response (CR) items to determine which was most effective in producing equivalent scores across two be equated. Using data from a large‐scale exam, investigated use anchor CR item rescoring (known as trend scoring) context classical methods. Four linking designs were examined: an with only MC items, mixed‐format test items; incorporating common...

Proposed within this work is a novel coal conversion process, dubbed the "dry gasification oxy-combustion" (DGOC) power cycle. In unique two-stage feed partially oxidized at high pressures in an oxygen-blown, fluidized-bed unit, using recycled flue gas as agent (≈61% CO2 and 32% H2O). addition, reducing environment of gasifier provides opportunity to perform pre-combustion sulfur removal through sorbent-based capture. The second stage, oxy-combustion, also uses gas, for temperature...
