Hi, everyone, and thank you for your interest in this work.
My name is Maxine Daniel from ESTIA Institute of Technology.
And today I will be talking about our work
exploring the allure and the purposes of cylindrical shape-change for ambient display.
First, in this work, we performed a brainstorming session
around the purposes of a cylindrical shape display.
As a result, we generated 16 potential
applications that we organized in four purpose categories.
In the first category, we put applications that communicate
information using data physicalization such as informing users about tide, wind
or sun forecasts, for example, in the entrance hall of a seaside resort,
and informing user about parking slot availability in a multi-level garage.
Moreover, we found other applications communicating information,
using tangible representation, examples include indicating the direction
to users using physical up or down arrow, notifying users about data transfert state using
physical download or upload animation, and alarming users using a physical ringing bell animation.
In the second category, we identified applications that simulate
real-world objects using tangible embodiment such as a light bulb
for illuminating a room, an hourglass for measuring time
in a kitchen, and Hanoï towers for puzzle solving in a classroom.
In the third category, we put applications with hedonic purposes
such as a Christmas tree for decorating a living room,
a Champagne fountain for welcoming guests at a wedding reception,
and a dynamic soundwave sculpture for entertaining the audience at the concert.
In the last category, we found one application making use
of adaptive affordance. We imagined a persona, Brian, who is cooking
a meal in the kitchen and asks for a 10-minute timer to his home assistant.
As a response, the home assistant morphs into a 10-minute hourglass.
While Brian is waiting for the timer to finish,
he asks for his favorite music playlist.
In return, the home assistant moves the timer
in the background and morphs into a dynamic soundwave scuplture.
Ten minutes later,
the assistant morphs into a ringing bell to alarm the user that the timer is over.
In the second part of this work, we performed a two-month study
in a workplace to get feedback on the allure of a cylindrical shape display.
For two months, we deployed a flat display
and a cylindrical shape display in two open offices of the same workplace.
Both displays show a vertical histogram
visualizing forecasts of renewable energy production for each hour of a working day.
During each working day,
the histogram shows variations one after the other
which enables users to focus on one peak hour at a time.
Using this histogram and the following instructions,
employees were encouraged to charge
their laptop battery during peak hours of renewable energy production.
The results of the study indicate that a cylindrical display is as useful as
a flat display, but more enjoyable than a flat display when it comes to help
employees to shift laptop battery charge using an histogram.
Participants declared that axisymmetric shape-change was fascinating,
was still fascinating, even after two months of deployment.
