New HCI techniques for better living through technology

In the Human Computer Interaction community, researchers work on many 
projects that investigate the efficacy of new technologies for better living, 
but unlike other research fields, these researchers must have an approach 
that is typically multi-disciplinary. 
Technology is always developing thus improving our lives in many ways 
like education, health and communication. This due to the fact that it is 
supposed to make life easier. 
This dissertation explores three main aspects: the first is learning with 
new technologies, the second is the improvement of real life by using innovative 
devices while the third is the usage of mobile devices in combination 
with image processing algorithms and computer graphics techniques. 
We firstly describe the progress on the state of the art and related work 
that have been necessary to implement such tools on commodity hardware 
and deploy them in both mobile and desktop settings. 
We propose the usage of different technologies in different settings, comparing 
these solutions for enhancing the interaction experience by introducing 
virtual/augmented reality tools for supporting this kind of activities. 
We also applied well-known gamification techniques coming from different 
mobile applications for demonstrating how users can be entertained and 
motivated in their working out. 
We describe our design and prototype of several integrated systems created 
to improve the educational process, to enhance the shopping experience, 
to provide new experiences for travellers and even to improve fitness 
and wellness activities. 
Finally, we discuss our findings and frame them in the broader context 
of better living thanks to technology, drawing the lessons learnt from each 
work while also proposing relative future work.
