Agenda

• so far we have examined media in isolation and in
  combination, we have looked at multimedia systems
  from the point of view of the interfaces they
  present to users and modelling the applications
  that sit behind the interface
• you will recall that in the first lectures we
  claimed that multimedia systems are different to
  other traditional systems
• now we draw our attention back to the user again
  to consider those aspects of multimedia systems
  which are absent from conventional systems that
  use multiple media
• they include
• Interaction and Interactivity
• Usability and Actability

Interaction Interactivity

Degrees of Interactivity

• interactivity is an extremely difficult concept
  to grasp, yet it appears to be central to any
  definition of multimedia- we tend to know it when
  we have it
• interactivity is a kind of defining
  characteristic which separates multimedia from
  other types of systems or systems which utilise
  multiple media
• in the apparent absence of a theory of
  interactivity from within the field of
  organisational multimedia, we turn in stead to
  traditional education and pedagogic applications
  of multimedia and see what insights this theory
  can provide (if any)

Interaction Interactivity

• as with most aspects of user interface design and
  multimedia systems in particular, surprising
  little is known about the nature of interaction
  and interactivity
• we must be able to understand these issues
  because
• they are central to understanding the
  differences between conventional information
  systems that display information in the form of
  collections of multiple media versus multimedia
  systems

selected- is an application that supports
multiple media but is not a multimedia system

Interaction Interactivity

• interactivity is central to any definition of
  multimedia
• it is arguably the most crucial means by which
  other systems supporting multiple media can be
  distinguished from multimedia systems
• there are several ways in which interactivity can
  be understood- a long standing way of
  understanding interactivity is by theorising it
  from an education psychology (learning theory)
  approach

Interaction Interactivity

• the images opposite are from the OnSite! 3.0
  training CD-ROM developed by CEDIR at UoW for the
  construction industry
• the top most image is the opening screen which
  uses an office metaphor as a kind of generalised
  desktop metaphor
• various courses are available by clicking the
  filing cabinet shown in the bottom sequence of
  images
• OnSite! contains a range of learning resources
  for building and construction workers, trainees,
  apprentices and students. It is flexible,
  interactive and engaging, with a mix of text,
  illustration, animation and video material
