Technologies for Teaching

Redefining learning through technology

MultiPresenter takes advantage of lecture halls with multiple projectors, allowing them to be used flexibility and independently where appropriate.

In this series of works, we explore the role of large display and mobile technologies within the context of a university classroom. We explore how multiple displays can be used in ways that go beyond mirroring the display of the presenter (Lanir, Booth, & Tang, 2008), and how we can blur the lines between learners and instructors by challenging conventional notions of control across shared displays (Lanir, Booth, & Tang, 2010). These designs are built from careful studies of how people make use of large displays (Tang, Lanir, Greenberg, & Fels, 2009; Tang, Parker, Lanir, Booth, & Fels, 2006). A more recent design explored how sketching could be used as an input mechnism for a large display designed for teaching math (Grossauer, Perteneder, Haller, Walny, Brosz, Tang, & Carpendale, 2012) or for brainstorming (Peterender, Grossauer, Seifried, Walney, Brosz, Tang, Carpendale, & Haller, 2012).
