Smartphones and Bouncy Structures – What do they have in common?


Atreyu de Lacy will elaborate on the general process of developing a technical engineering app and will discuss the inner mechanics of the Vibrate-It app that he helped to develop.

When: 6:15pm, Monday,  3 October 2016

Where: Lecture Theatre C1 (Building 174, Room 407), 4th Floor, Engineering Building Block C, University of Melbourne, Parkville

Refreshments will provided from 5:45pm in Room C301 (Building 174), 3rd Floor, Engineering Block C

The rise of mobile technology has seen mobile phone ownership in the last 20 years rapidly rise from 0% to around 100% across almost every nation in the world; it is currently estimated that there are almost 7 billion mobile phone subscriptions globally. This massive growth has driven the development of mobile technology to the point where modern smartphone’s processing power far exceeds that of the worlds earliest supercomputers, and now possess additional features as standard such as GPS, high resolution camera’s, and sensitive accelerometers. Despite this rapid development, the number of engineering related apps available for either android or apple represent a very small fraction of a percent of the ~1.5 billion apps available for download today. The portion of those apps that actually harness the full potential of the in-built hardware is even fewer again. 

During his time working for Expedition Engineering in London, Atreyu was part of a small group of engineers who developed a new Android app that looked to answer the question - just what can a modern smart phone do? 

That work resulted in the app, ‘Vibrate-It’, which uses the in-built accelerometers in your smartphone, to record, process, and interpret raw acceleration data in real time. This proof-of-concept study demonstrated that simultaneously harnessing both the in-built accelerometers and the incredible processing power of smartphones could one day replace slow and expensive testing equipment and procedures, and , eventually, lead to improved standards and design criteria. This work was also published in The Structural Engineer publication, based on a specific case study of a lightweight sculptural staircase at the IStructE HQ in London, designed by Expedition.

Atreyu will elaborate on the general process of developing a technical engineering app, discuss the inner mechanics of the Vibrate-It app and planned/ongoing improvements and additions.

About the speaker:

Atreyu de Lacy is a Chartered Structural Engineer with 10+ years’ experience working for leading consultancies in Australia and the UK, during which time he has worked on a diverse range of challenging projects including commercial and residential high-rise developments, institutional and cultural buildings, sporting facilities and government projects - within Australia, UK, Europe, and the Middle-East. Atreyu has a keen interest in structural dynamics related fields, including assessment and testing of vibration effects due to human footfall and other sources.
