Resumo(s)
This Master thesis studies how Public Ambient Displays (PAD) can be used as a tool
to achieve behaviour change, through persuasive technology.
In order to reach the goals of the thesis, an interactive public ambient display system
called Motion-based Ambient Interactive Display (MAID) was developed. MAID is driven
to motivate behaviour changes regarding domestic energy consumption, through a
persuasive game interface based on gesture recognition technology. The developed
prototype guides players through the different rooms of a house, where they have to find out what is wrong and practice the correct actions to save energy, using similar gestures to the ones they would use in real life to achieve the same goals. The system provides feedback regarding the consequences of each action, in order to make users aware of the consequences of their actions.
The implementation of MAID is based on a purpose built, highly configurable and
modular framework. It allows the administrator to fine tune and tweak the application to the necessities of the setup location constraints, by adjusting basic display properties, change image content or even modify the scripted gameplay itself. The scripted game system is flexible enough to allow the repurposing of the framework, beyond the previously defined theme, for future studies.
The MAID was subjected to user testing, in order to show that it is possible to create
a persuasive PAD interface, using seamless interaction methods, with the currently available technology, and use it to spread awareness of a cause, leading to behaviour change.
