Eliciting affordances for Smart Objects in IoT EraAssunta Matassa, Rossana Simeoni
01
Affordancesproperties as 'natural elements' existing in objects and which help people to interact
with the objects themselves.

!We define two kind of affordances:!!
✤ Cognitive affordance is associated with semantics or meaning of artefacts. It is help with a priori knowledge;!
✤ Physical affordance is a design features that helps, aids, supports enables doing something physically.
Internet of Things opens a new opportunities in exploiting objects’ properties. !The evolution is going in the direction of changing the shape and the appearance of
objects augmenting their natural function with something new.
Smart Objects goes beyond what its aspect shows and what people can image, combining
knowledge and insights derived from the original physical object.!!!
The impossibility of establishing a clear connection between objects and functionalities could become a threat for humans, since they are missing their innate ability to
understand what they can do only based on their knowledge and perception of the surrounding context.!
01
Cognitive dissonance
The distance between physical affordance, object property suggesting interaction, and cognitive affordance, !
the way people perceive how they could interact with object, can be formalized using psychological definition of !
cognitive dissonance.!Cognitive Dissonance is the perceived inconsistency between knowledge, feelings and behaviour establishes an inner state of discomfort - cognitive
dissonance - that people try to reduce.
Mind the gap…
PAST!In order to obtain innovative services, we tried to combine the power of a traditional book with the capabilities offered by new
technologies.
01
NOW!!
The final result conceptualises a new smart book which integrates the
advanced technology of digital books with the affordances of physical books to facilitate people’s information revisiting
process.!
!Using a top-projector to create digital
content on a blank paper book.!
!!!
The aim is to generate a natural reading experience.!

This project can be a good example of blindness behind !this process:!
the result appears as something very ambiguous for users because the attention focus on the introduction !
of !tradition affordances in a smart object.
How ambiguity could support the design process in IoT Era?
01
Ambiguity
could represent a source of innovation and creativity to support the development of a good design and keep the attention on users' behaviour and needs.

We intend to exploit the lack of clear principles for eliciting affordances or new meanings in smart objects by suggesting
a design research method, on top of !the critical design approach.
Critical Design
In contrast with traditional design that reinforce the status quo and the pre-existing situation, critical design uses speculative design proposals to challenge the narrow assumptions, preconditions and stimulates the
reflection about the role of object in everyday life.!

and rebuild objects and behaviours.

Setting up an experiment
Step one
✤ Define a set of everyday objects and then observe which way people interact with them, how they adopt affordances and how they apply different meaning while getting
in touch with them. !✤ Using ethnography, the aim is to understand how affordances are already in use, the
smart objects in the “context of use" and highlight the existing interrelationships between users and objects, and users and users with smart objects.

Step two
✤ We propose “in the wild” a set of smart objects, strictly related to the objects of the previous step, containing ambiguity in meaning and affordances and then observe the
‘adaptive behaviour’ that people act as natural consequences of a state of cognitive dissonance.!
✤ The aim is to understand the new meaning of smart object. We are encouraged to understand how traditional affordance are in use in smart object, how people underline
new kind of affordances.
