learning non visual Graphical information using a touch based vibro audio interface
Conference on Computers and Accessibility, 2012Co-Authors: Nicholas A Giudice, Hari Prasath Palani, Eric Brenner, Kevin M KramerAbstract:This paper evaluates an inexpensive and intuitive approach for providing non-visual access to graphic Material, called a vibro-audio interface. The system works by allowing users to freely explore Graphical information on the touchscreen of a commercially available tablet and synchronously triggering vibration patterns and auditory information whenever an on-screen visual element is touched. Three studies were conducted that assessed legibility and comprehension of the relative relations and global structure of a bar graph (Exp 1), Pattern recognition via a letter identification task (Exp 2), and orientation discrimination of geometric shapes (Exp 3). Performance with the touch-based device was compared to the same tasks performed using standard hardcopy tactile graphics. Results showed similar error performance between modes for all measures, indicating that the vibro-audio interface is a viable multimodal solution for providing access to dynamic visual information and supporting accurate spatial learning and the development of mental representations of Graphical Material.

Computer‐based Learning in Statistics: a Problem Solving Approach
Journal of the Royal Statistical Society: Series D (The Statistician), 1998Co-Authors: Adrian Bowman, W. Harper Gilmour, Gillian Constable, Neville Davies, Steven G. Gilmour, Edwin J. RedfernAbstract:Summary. Software which allows interactive textual and Graphical Material to be created relatively easily has now existed for several years. This has promoted considerable interest in computerbased learning. This paper describes an approach which uses these tools to create problem-based Material for use in laboratory sessions in association with courses in statistics. Illustrations are given, and the presentation of one particular problem, based on the design and analysis of a simple clinical trial, is developed in detail. Important issues of design, construction and evaluation are also discussed. It is argued that, although it is expensive to produce, Material of this type can provide real benefits as a teaching resource.

The birds and the bees: interactive graphics and problem solving in the teaching of statistics
Statistics and Computing, 1997Co-Authors: Adrian Bowman, James Currall, Richard LyallAbstract:Software which allows interactive exploration of Graphical displays is widely available. In addition there now exist sophisticated ‘authoring tools’ which allow more general textual and Graphical Material to be presented in computer-based form. The role of an authoring tool in providing a Graphical interface to a strategy for solving simple statistical problems in the context of teaching is discussed. This interface allows a variety of resources to be integrated. Specific examples, including the use of dynamic Graphical displays in exploring data and in communicating the meaning of a model, are proposed. These ideas are illustrated by a problem involving the identification of the sex of a herring gull.
