An overarching goal of interaction design
is to develop interactive systems that elicit positive responses
from users, such as feeling at ease, being comfortable, and
enjoying the experience of using them. More recently, designers
have become interested in how to design interactive products
that elicit specific kinds of emotional responses in users,
motivating them to learn, play, be creative, and be social.
There is also a growing concern with how to design websites
that people can trust, that make them feel comfortable about
divulging personal information or making a purchase.
We refer to this newly emerging area of interaction
design as affective aspects. In this chapter we look at how
and why the design of computer systems cause certain kinds
of emotional responses in users. We begin by looking in general
at expressive interfaces, examining the role of an interface's
appearance on users and how it affects usability. We then
examine how computer systems elicit negative responses, e.g.,
user frustration. Following this, we present a debate on the
controversial topic of anthropomorphism and its implications
for designing applications to have humanlike qualities.
Finally, we examine the range of virtual characters designed
to motivate people to learn, buy, listen, etc., and consider
how useful and appropriate they are.
The main aims of this chapter are to:
- Explain what expressive interfaces are
and the affects they can have on
- Outline the problems of user frustration
and how to reduce them.
- Debate the pros and cons of applying
anthropomorphism in interaction
- Assess the believability of different
kinds of agents and virtual characters.
- Enable you to critique the persuasive
impact of ecommerce agents on customers.
