Genie in the Bottle: Anthropomorphized Perceptions of Conversational Agents

This paper presents a qualitative multi-phase study seeking to identify patterns in users' anthropomorphized perceptions of conversational agents. Through a comparative analysis of behavioral perceptions and visual conceptions of three agents — Alexa, Google Assistant, and Siri — we first show that the perceptions of…

Leveraging Distal Vibrotactile Feedback for Target Acquisition

Many touch based interactions provide limited opportunities for direct tactile feedback; examples include multi-user touch displays, augmented reality based projections on passive surfaces, and mid-air input. In this paper, we consider distal feedback, through vibrotactile stimulation on a smart-watch placed on the us…

Introducing Transient Gestures to Improve Pan and Zoom on Touch Surfaces

Despite the ubiquity of touch-based input and the availability of increasingly computationally powerful touchscreen devices, there has been comparatively little work on enhancing basic canonical gestures such as swipe-to-pan and pinch-to-zoom. In this paper, we introduce transient pan and zoom, i.e. pan and zoom mani…

FingerArc and FingerChord: Supporting Novice to Expert Transitions with Guided Finger-Aware Shortcuts

Keyboard shortcuts can be more efficient than graphical input, but they are underused by most users. To alleviate this, we present "Guided Finger-Aware Shortcuts" to reduce the gulf between graphical input and shortcut activation. The interaction technique works by recognising when a special hand posture is used to pr…
