Human activity recognition has potential to impact a wide range of applications from surveillance human computer interfaces content based video retrieval. Recently, the rapid development inexpensive depth sensors (e.g. Microsoft Kinect) provides adequate accuracy for real-time full-body tracking applications. In this paper, we create complex dataset depicting two person interactions, including synchronized video, and motion capture data. Moreover, use our evaluate various features typically...
Human replicas may elicit unintended cold, eerie feelings in viewers, an effect known as the uncanny valley. Masahiro Mori, who proposed 1970, attributed it to inconsistencies replica’s realism with some of its features perceived human and others nonhuman. This study aims determine whether reducing consistency visual increases valley effect. In three rounds experiments, 548 participants categorized rated humans, animals, objects that varied from computer animated real. Two sets were...
Computer-modeled characters resembling real people sometimes elicit cold, eerie feelings. This effect, called the uncanny valley, has been attributed to uncertainty about whether character is human or living real. Uncertainty, however, neither explains why anthropomorphic lie in valley nor their characteristic eeriness. We propose that realism inconsistency causes appear unfamiliar, despite physical similarity people, owing perceptual narrowing. further fake appearance elicits feelings,...
Including older adults as full stakeholders in digital society.
Virtual humans are computer-generated characters designed to simulate key properties of human face-to-face conversation---verbal and nonverbal. Their human-like physical appearance nonverbal behavior set them apart from chatbot-type embodied conversational agents, has recently received significant interest as a potential tool for health-related interventions. As healthcare providers deliberate whether adopt this new technology, it is crucial examine the empirical evidence about their...
To maintain their quality of life and avoid hospitalization early mortality, patients with heart failure must recognize respond to symptoms exacerbation. A promising method for engaging in self-care is through mobile health applications (mHealth apps). However, mHealth have its greatest chance improving patient outcomes, the app content be readable, provide useful functions based evidence. The study aimed determine: (1) readability, (2) types functions, (3) linkage authoritative sources...
Older adults often struggle to locate a function quickly in feature-rich user interfaces (UIs). Mobile UIs not only pack ton of features small screen but also get frequent updates their visual layouts—thereby exacerbating the problem. This paper explores design solution where users could search for UI feature using spoken-word queries. We investigated: 1) what type questions older ask when facing interaction challenges unfamiliar scenarios, 2) how those query types compare with younger...
As mobile user interfaces (UI) become feature-rich, navigation gets more complex. Finding features quickly starts demanding information-intensive strategies for decision-making—which can be challenging older adults. Older adults examine fewer details, requiring cognitive resources, when searching information with a large number of alternatives. In this paper, we first systematically various ways to convey reduced feature space. Visually emphasizing three relevant options helped find specific...
Researchers are exploring touchless interactions in diverse usage contexts. These include interacting with public displays, where mouse and keyboards inconvenient, activating kitchen devices without touching them dirty hands, or supporting surgeons browsing medical images a sterile operating room. Unlike traditional visual interfaces, however, systems still lack standardized user interface language for basic command selection (e.g., menus). Prior research proposed menus that require users to...

Recent advancements and economic feasibility have led to the widespread adoption of conversational digital assistants for everyday work. While research has focused on use these such as Siri, Google Assistant or Alexa, by young adults families, very little work focuses acceptance adaptability amongst older adults. This SIG aims discuss benefits well being The goals this are to: (i) explore acceptance/adoption voice-based agents (ii) anthropomorphism in design assistants. (iii) understand...
Despite a global upward trend in mobile device ownership, older adults continue to use few applications and fewer features. For example, besides directions, maps provide information about public transit, traffic, amenities. Mobile can assist navigate independently, avail city facilities, explore new places. But how accessible are current adults? In this paper, we present results from qualitative study examining the difficulties they encounter. 172 problems were identified categorized across...
In day-to-day life, older adults prefer getting tech support from loved ones, rather than relying on instruction manuals or institutional support. But asking for help, frequently repeatedly similar issues, can strain relations between and their helpers. This paper examines how relationships are maintained when younger helpers give get support—across three different cultures: North American, South Asian, Middle Eastern. Our deductive application of the relational maintenance strategies...
Slide presentations have long been stuck in a one-to-many paradigm, limiting audience engagement. Based on the concept of smartphone-based remote control slide navigation, we present Office Social-a PowerPoint plugin and companion smartphone app that allows members qualified access to slides for personal review and, when presenter enables it, public over navigation. We studied longitudinal use Social across four meetings workgroup. found shared regulated facilitated various forms discuss how...
Far more older adults are using mobile devices now than a decade ago. However, the applications they use continue to lag in depth (features) and breadth (diversity). Despite large body of research on designing technology with identifying their adoption difficulties, we know little about how users prefer learn or troubleshoot following an initial ownership. In this paper, first review existing models by that consider learning as factor discuss limitations. Then interview who (n = 23) younger...
Traditional models of slideware assume one presenter controls attention through slide navigation and pointing while a passive audience views the action. This paradigm limits group interactions, curtailing opportunities for attendees to use slides participate in collaborative discourse. However, as permeates contexts beyond simple one-to-many presentations, there are growing efforts shift dynamics collocated interactions. Technologies exist information control variations that extend functions...
Drug–drug interaction (DDI) alerts safeguard patient safety during medication prescribing, but are often ignored by physicians. Despite attempts to improve the usability of such alerts, physicians still mistrust relevance simplistic computerized warnings support complex medical decisions. By building on prior fieldwork, this paper evaluates novel designs trust–eliciting cues in DDI alerts. A sequential mixed-method study with 70 examined what trust compliance, promote reflection, and trigger...
