Mid-air interaction is a distinct style of natural HCI (Human-Computer Interaction). In mid-air
interaction, users make use of their whole body—with a strong focus on hands—and apply …

One of the most useful tools in human-computer interaction is the task model, a structured
decomposition of user actions toward a goal. Task models can predict average human …

This work compares four mid-air target selection methods (Push, Tap, Dwell, Pinch) with two
types of ultrasonic haptic feedback (Select, HoverSelect) in a Fitts' law experiment. Results …

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 …

User interfaces based on touchless hand gestures have advantages over conventional user
interfaces in a variety of scenarios. However, they still have challenging problems to be …

Touchless mid-air gestural interaction has gained mainstream attention with the emergence
of off-the-shelf commodity devices such as the Leap Motion and the Xbox Kinect. One of the …

Different from mouse-based and touch-based interactions at a static distance, motion-
sensing interaction on a large display is typically performed at varying distances ranging …

Remote pointing is an input method that involves in-air gesticulation. Target selection via
Leap Motion-based remote pointing and mouse-based pointing were compared while …

In motion-sensing interaction with large displays through bare hands, we can observe that
users alternate their hands and move their bodies frequently. What cause such actions and …

Fitts' law is a standard tool for assessing user performance and interaction device
effectiveness in human-computer interaction (HCI). However, it disregards spatial variables …
