Reducing consistency in human realism increases the uncanny valley effect; increasing category uncertainty does not
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… Expand

Familiar faces rendered strange: Why inconsistent realism drives characters into the uncanny valley
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… Expand

Categorization-based stranger avoidance does not explain the uncanny valley effect
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… Expand

Beyond Presentation: Shared Slideware Control as a Resource for Collocated Collaboration
TLDR
We report on a detailed naturalistic case of using presentation in a design meeting, where participants used Office Social, an experimental slideware technology that enabled open access to shared interaction with slides across multiple devices. Expand

Understanding Visual Feedback in Large-Display Touchless Interactions: An Exploratory Study
TLDR
We investigate how large-display touchless interactions are affected by (1) types of visual feedback—discrete, partial, and continuous; (2) alternative forms of touchless cursors; (3) approaches to visualize target-selection; and (4) persistent visual cues to support out-of-range and drag-and-drop gestures.

Motor-Intuitive Interactions Based on Image Schemas: Aligning Touchless Interaction Primitives with Human Sensorimotor Abilities
TLDR
We operationalized intuitive touchless interaction using the intuitive interaction framework, and demonstrated how user performance of a motor-intuitive, touchless primitive based on sensorimotor knowledge (image schemas) is affected by biomechanical factors. Expand
