A semantic analysis of the design space of input devices

A bewildering variety of devices for communication from humans to computers now exists on the market. In this article, we propose a descriptive framework for analyzing the design space of these input devices. We begin with Buxton's (1983) idea that input devices are transducers of physical properties in one, two, or three dimensions. Following Mackinlay's semantic analysis of the design space for graphical presentations, we extend this idea to more comprehensive descriptions of physical properties, space, and transducer mappings.

A morphological analysis of the design space of input devices

The market now contains a bewildering variety of input devices for communication from humans to computers. This paper discusses a means to systematize these devices through morphological design space analysis, in which different input device designs are taken as points in a parametrically described design space. The design space is characterized by finding methods to generate and test design points. In a previous paper, we discussed a method for generating the space of input device designs using primitive and compositional movement operators.

Alternative Access Technologies

This chapter explores current tools and techniques used to access electronic assistive technologies and how they can be used by clients with a range of disabilities. The chapter suggests a general assistive technology model in which access technologies can be considered, and defines the component parts of the model. We then discuss and define the range of access technologies that are currently available, including keyboards, touchscreens, pointing devices, eye gaze; switch access, speech recognition and brain–computer interfaces.

Handbook of Electronic Assistive Technology

Electronic Assistive Technology (EAT) is a subset of a wider range of products and services known as Assistive Technology (AT). AT is designed to support and enable people with disabilities, either acquired or congenital, to participate in activities with greater independence and safety. With a global aging population, it has an important role to play in enabling and supporting those with disability and their carers.
