Abstract
Gesture-based computing refers to interfaces where the human body interacts with digital resources without using common input devices, such as a keyboard, mouse, game controller, or voice-entry mechanism. The introduction of the mouse allowed computer inputs to move beyond the linear dimension of the keyboard to two dimensions; gesture-based computing is the next step in that evolution, enabling three-dimensional input that involves users in the computing activity. These interfaces could enable a more active and intuitive learning style that often seems more like play, and one particularly promising area is the combination of gesture-based computing with augmented reality. Gesture-based systems may offer new ways to interact with immersive 3D content and to investigate immersive scenarios.
The 7 Things You Should Know About... series from the EDUCAUSE Learning Initiative (ELI) provides concise information on emerging learning technologies. Each brief focuses on a single technology and describes what it is, where it is going, and why it matters to teaching and learning. Use these briefs for a no-jargon, quick overview of a topic and share them with time-pressed colleagues.
In addition to the 7 Things briefs, you may find other ELI resources useful in addressing teaching, learning, and technology issues at your institution. To learn more, please visit the ELI Resources page.
