Computer-modeled characters resembling real people sometimes elicit cold, eerie feelings. This effect, called the uncanny valley, has been attributed to uncertainty about whether the character is human or living or real. Uncertainty, however, neither explains why anthropomorphic characters lie in the uncanny valley nor their characteristic eeriness...

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, and amenities. Mobile maps can assist older adults to navigate independently, avail city facilities, and explore new places. But how acce...

People use touchless input when interacting with virtual or augmented reality. During those interactions, they may alternate between hands or use both hands simultaneously. How does handedness impact user performance in touchless input? We hypothesized that touchless input, owing to lower demand for feedback control, will produce much less between-...

Older adults often struggle to locate a function quickly in feature-rich user interfaces (UIs). Mobile UIs not only pack a ton of features in a small screen but also get frequent updates to their visual layouts-thereby exacerbating the problem. This paper explores a design solution where users could search for a pertinent UI feature using spoken-wo...

Cultural, socioeconomic, and geographical issues are some of the contextual factors that make older adults unique. That cognitive and motor abilities change-mostly worsen-with age is well-known in the literature and has been the primary focus of HCI research in the past. More recently, socioeconomic factors such as agency and privacy of older adult...

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 to participate in a collaborative discourse. However, as slideware permeates contexts beyond simple one...

The uncanny valley hypothesis predicts that an entity appearing almost human risks eliciting cold, eerie feelings in viewers. Categorization-based stranger avoidance theory identifies the cause of this feeling as categorizing the entity into a novel category. This explanation is doubtful because stranger is not a novel category in adults; infants d...

We use gestures frequently in daily life—to interact with people, pets, or objects. But interacting with computers using mid-air gestures continues to challenge the design of touchless systems. Traditional approaches to touchless interaction focus on exploring gesture inputs and evaluating user interfaces. I shift the focus from gesture elicitation...

Human replicas may elicit unintended cold, eerie feelings in viewers, an effect known as the uncanny valley. Masahiro Mori, who proposed the effect in 1970, attributed it to inconsistencies in the replica's realism with some of its features perceived as human and others as nonhuman. This study aims to determine whether reducing realism consistency...

Safe prescribing of medications relies on drug safety alerts, but up to 96% of such warnings are ignored by physicians. Prior research has proposed improvements to the design of alerts, but with limited increase in adherence. We propose a different perspective: before re-designing alerts, we focus on improving the trust between physicians and compu...

Elicitation and evaluation studies investigated intuitiveness of touchless gestures but did not operationalize intuitiveness. For example, studies found that users fail to make accurate 3D strokes as interaction commands. But this phenomenon remains unexplained. In this paper, we first explain how making accurate 3D strokes is generally unintuitive...

Large, high-resolution displays enable efficient visualization of large datasets. To interact with these large datasets, touchless interfaces can support fluid interaction at different distances from the display. Touchless gestures, however, lack haptic feedback. Hence, users' gestures may unintentionally move off the interface elements and require...
