Making the BodyBug
BodyBug is a climbing gadget that makes use of bodily movements in order
to create a physical dialogue between you and the machine,as well as the environment.
When you feed BodyBug with movement impulses it will move along a path that
is placed on your body. Depending on how you move BodyBug will respond to you
in different ways. BodyBug could be used in optional contexts and in optional
ways in order to support your own personal expressions and impressions.
And one thing is for sure - you are going to move!
BodyBug is a prototype developed within the doctoral project of Jin Moen working
at Interactive Institute Share Studio. This paper will present the aim and background
of the design process, and the problems and issues raised during the ongoing
prototype development process.
Background
The problem area of the doctoral project is physical interaction, i.e. the use
of the human body as an interaction tool, or bodily movements as an interaction
modality. Starting from the proposition that a lot of these interfaces are developed
on the basis of the available technology rather than the needs of the potential
user, this project aims at taking a new approach to the process of designing
and developing physical full body interfaces. When designing interfaces that
make use of bodily movements a basic understanding of how we use our body in
an expressive and communicating way should be cleared out. This includes exploring
different interaction aspects of bodily movements, and how the user and the
environment experience them. By conducting ethnographically informed studies
of nine persons attending a 13-week course of Physical Expression that were
based in modern dance, we tried to establish some important aspects of physical
interaction. The course's aims were to introduce movement as a form of knowledge;
create understanding, experience and knowledge of the body and movement as means
for expression and communication; develop the personal movement language; provide
possibilities to express ideas using movements individually and in groups; provide
a basis for explorative work processes; and develop ideas on movement interaction
in relation to digital media. During multiple interviews and written exercises
the participants expressed their experience of the course and the activities
carried out in the dance studio, as well as the two design workshops included
in the course. The aim of this part of the project, i.e. making a prototype,
is to give an example of a full body movement interface that is designed for
and based on the human body and its movement conditions. This means that the
issues that came up regarding bodily communication and movement interaction
during the empirical study have been exhaustively discussed and considered,
and used as a starting point for the prototype design.
The Starting Point for the Prototype Development
Some important aspects on bodily interaction that aroused from the participants
during the study were the following:
- People have different movement patterns that are very individual.
- People interpret the same task in different ways.
- Interaction should feel good, and it does whenthere is harmony and flow in
it.
- Harmony and flow are experienced when the performed movements suits your own
movement pattern.
- By trying to feel and sense your own body when moving you can learn to know
your own movement pattern.
- Moving the body includes the whole physical body, thoughts and emotions.
- A person's individual experiences of his or hers personal sphere and physical
limits are affecting how comfortable he or she feels being close to another
person or device.
- The relevancy and acceptance of bodily interaction is related to in which
context it is used.
- Exploring and experiencing movement is fun but also personally self-revealing.
These aspects might be considered as very obvious when it comes to interaction
and communication. But what was important in this study was that they were self-experienced.
Some of the participants were surprised that these issues were that important
and affected their behaviour and emotions and thus interaction and communication.
But they also learned to cope with and kind of control some of their behaviour.
In the prototype development we wanted to reflect these aspects. We also had
some other initial constraints that we wanted to fulfil. Those were:
- Develop a tangible object or artefact and not a system.
- The artefact should be mobile, and independent of place and context. (Not
meaning that the place and context will not affect the interaction or the experience!)
- The user group aimed for was non-disabled grown-ups.
- The artefact could be used individually and in groups.
- The artefact should trigger movements.
In addition we had some ideas of what we did not want to do or work with, e.g.
biological sensors, different kinds of techniques for screening the user, visualising
or representing information. This was in respect to the user control that we
wanted to convey in the interaction designed. We also wanted to give room for
individual expressions. Considering the results from the empirical study and
our initial constraints we started out the design process by having a two-day
concept development workshop that are described in the following section.
The Concept Development
The concept development workshop was carried out during two days in October,
with Johan Sandsjö and Jin Moen as the only participants. We had met for
the first time at the Convivio Summer School in Split one month earlier and
found that our common interests were movement and physical interaction. Prior
to the workshop we had some mail contact, bringing up issues that we wanted
to explore when it came to bodily interaction, movements etc. But
we had had no real discussions whether on what to make or how to do that. We
started out the workshop by deciding to have a mock-up ready by the end of the
second day, just to have a clear goal of where we were heading. Our first activity
was to discuss different issues of movement, interaction, and what the prototype
should stand for, and reread some of the previous mail communication. Some of
the words and notions that came up were physical memories, balance, the body
as a haptic display, "visible" interaction, touch, surface, personal
space, contact, direction, gravity, movement impulse, object, full scale, "no
hands", "unconscious" movement, initiating movement, socially
accepted movements.
