AR Navigation System for Pedestrians – Android App

By android, Augmented Reality No Comments

Sung-Hyun Jang, one of my Ph.D. students here at CASA, has launched an Android app called AR Navigation System for Pedestrians.
The app is a part of his Ph.D. studies, and is an attempt at visualising geographic information via an augmented reality interface.  Specifically, the app provides navigation information via both map interface and an augmented reality interface.

The app was written in Java using the Android SDK, and uses the Google Maps API and the Google Direction API. Going forward, Sung is looking to use the app to research Human-Computer Interaction (HCI) and in particular to help him investigate spatial knowledge acquisition.

The app is available at Google Play. (https://play.google.com/store/apps/details?id=com.pinenutapps.arnavi)

Developing Classical and Contemporary Models in ESRI’s City Engine – CASA Working Paper 191

CASA Working Paper 191 – Developing classical and contemporary models in ESRI’s City Engine – is now available to download.

Abstract

Working Paper 191

Working Paper 191

In this paper we describe the development of projects which aim to explore the use of procedural modelling as a complete toolkit for building interactive visualizations of urban modelling theories. We will use three case studies, starting with the original von-Thunen model, a generalization of von-Thunen using multiple centres and finally the standard dynamic retail model by Wilson and Harris. We will discuss the advantages and limitations in using ESRI’s City Engine and the use of interactive techniques, to visualize and explore classical and contemporary urban modelling theories, by introducing spatial interaction and spatial dynamics within the simulation of a 3d city. In this framework, we provide a guide for developing urban models to aid better analysis and understanding of the urban environment through 3d urban visualizations, complexity theories and interactive systems.

Colours - London Live Weather

Colours: A Live London Weather Dashboard

By data visualization, Weather, Weather London No Comments

Here at The Bartlett Centre for Advanced Spatial Analysis we run a Davis Vantage Pro 2 unit with Solar and UV sensors from a rooftop on Tottenham Court Road. The current output is via our live ‘Weather Dials‘ page, which is all singing and dancing, complete with graphs and updates every 2 seconds. Sometimes however there is a need for something simpler, a dashboard style view that changes background colour to a variety of pantone shades according to temperature:

Colours – London Live Weather

Made with a tablet in mind and to hang on a wall, ‘Colours’ is designed to be a simple weather application for London at a glance, data updates every two seconds.

500 Words a Day...

500 Words a Day: Academic Writing

By Writing 2 Comments

Its not something many academics admit – but writing is hard, not for all, there are some academics who simply flow words but for many its a challenge. There is nothing worse than the blank page of a Word/LaTeX document, knowing you have 10,000 words to go and only a title or abstract in place. It also depends on your stage in an academic career. Researchers generally have more time during the day to, as the job title suggests, to research and therefore write, lecturers less time (increasingly so) and so on. That said, the ability to do anything else than write the paper/masters thesis/PhD chapter is strong, many academics are excellent in justifying just one more bit of research before they start writing.

If you go through a period of not writing, be it weeks or months, then the guilt as an academic starts to build up, we are meant to write papers as those around will often be only to keen to chip in during conversations. I see it across the board, from professors through to starting out researchers and students leaving the course essay until the last possible minute.  There is a  need to not only get over the fear of starting a new paper but to also form a pattern to take away the worry that can all too easily build up.

It turns out the answer is easy, who would of thought it, and thanks go to Sir Alan Wilson of CASA who i found sitting typing early one morning, turns out he always aims for: Write 500 words a day.

I am at the stage, as head of the department, that my day is not one of research, it is one of almost constant meetings, as such it is rare to find quality time to write. However 500 words is achievable, it can be fitted in between meetings either in one go or in small chunks.

Writing 500 words a day gives you 2,500 a week  – 10,000 a month which is easily a PhD chapter, two working papers, or one journal paper.

It may seem obvious, but it is all too easy to complete a long day without having any words on paper and the aim for 500 words a day is not a mountain. It is not the sometimes recommended 1000 words a day that can turn into a slog and all too easily lead to a writer’s block.

I’ve been doing it for a week – not long I’ll admit – but i have 1 journal article, 1 conference paper and two book chapters all due soon and it has taken away the worry, and if I’m honest the guilt, of simply doing the day job. I go home knowing i have completed the goal and i, therefore, see the completion point, its not building up to the scenario where I have to write 4000 words in a day.

I would add that if you dont reach 500 words, don’t try to write more the following day, unless it flows. The aim is to get into a pattern, a pattern that is long term. This blog post is just over 500 words, of course academic writing takes longer but for anyone out there worrying about output/deadlines/work load then i would suggest giving writing 500 words a day a try.
