Screen based presentation and interactivity are a crucial part of modern teaching and learning practice. The content displayed can vary between courses but commonly includes:
- PowerPoint and similar presentations
- Videos from DVD, other media or online repositories (up to near-cinema quality)
- Word processing documents, spreadsheets and other text-based applications
- Detailed graphs, charts, engineering drawings
- Fine arts materials – paintings, illustrations and other imagery
- Scientific modelling
- Medical imagery
- Visualisation, and virtual- and augmented-reality
Electronic display technology in learning and teaching has become increasingly widespread only since the late 1990s. Initially, presentation materials were prepared by experienced authors and the low resolution of displays inherently limited the production of content that was too small to read.
Today, the commoditisation of ICT means nearly every presenter uses a computer regularly and the vast majority now author their own materials – only rarely is a specialist graphic designer employed to assist.
The quality of contemporary display technology allows higher ambient light in teaching spaces and affords users the freedom to develop any materials they want.
At its very core, the role of AV in learning and teaching is to facilitate communication of ideas and information to an audience. The design of our display systems must support this by providing an environment within which appropriately prepared materials can be viewed and assimilated easily.
Our learning environments, and the display systems within them must then take account of:
- The task itself and how display must support it; and
- How our audience/users consume the presented materials
