The Evolution of First Person Vision Methods: A Survey
The emergence of new wearable technologies such as action cameras and
smart-glasses has increased the interest of computer vision scientists in the
First Person perspective. Nowadays, this field is attracting attention and
investments of companies aiming to develop commercial devices with First Person
Vision recording capabilities. Due to this interest, an increasing demand of
methods to process these videos, possibly in real-time, is expected. Current
approaches present a particular combinations of different image features and
quantitative methods to accomplish specific objectives like object detection,
activity recognition, user machine interaction and so on. This paper summarizes
the evolution of the state of the art in First Person Vision video analysis
between 1997 and 2014, highlighting, among others, most commonly used features,
methods, challenges and opportunities within the field.Comment: First Person Vision, Egocentric Vision, Wearable Devices, Smart

SCALABLE AR FOR BIM ON TELECOMMUNICATION NETWORK SITES
A growing number of research works, experiments and applications is investigating the potential at the intersection of augmented
reality (AR) and the architecture, engineering, and construction (AEC) industry. Project management, project communication,
collaborative design, maintenance and construction progress documentation, construction site safety, and training are some of the cases
that can benefit from blending real and virtual views through mobile devices. In recent years, research also highlighted how mixed
reality and building information modeling (BIM) could cooperate to provide effective communication between multiple agents and
closer interaction between digital information and the building site. Nevertheless, consolidated applications in these fields are still
limited, especially when compared to other areas of AR adoption. This paper presents the development of an AR-based mobile app for
exploring telecommunications tower sites and interacting with a related BIM database. The project aims to provide easy-to-use tools
to maintain both the physical assets and an up-to-date model. We discuss critical issues in developing a scalable and interoperable
application, supporting the feasibility study of similar solutions in the AEC sector
