QRator is a collaborative project between the UCL Centre for Digital Humanities (UCLDH), UCL Centre for Advanced Spatial Analysis (CASA), and UCL Museums and Collections, to develop new kinds of content, co-curated by the public, museum curators, and academic researchers, to enhance museum interpretation, community engagement and establish new connections to museum exhibit content.

The interactive system is designed to be non intrusive while enabling members of the pubic to simply type in their thoughts and interpretation of museum objects and click ‘send’. Their interpretation become part of the objects history and ultimately the display itself via the interactive label system to allow the display of comments and information directly next to the artefacts.

The project is powered by Tales of Things technology which has developed a method for cataloguing physical objects online and capture memories and stories via the Internet of Things. QRator takes the technology a step further bringing the opportunity to move the discussion of objects direct to the museum label and onto a digital collaborative interpretation label, users’ mobile phones, and online allowing the creation of a sustainable, world-leading model for two-way public interaction in museum spaces.


At its heart QRator is an iPad/iPhone and web based system that allows everyone to be a curator and share their views on an exhibition. Visitors can examine an object before leaving their thoughts via an iPad to create a digital, ‘living’ label that subsequent visitors can read and respond to.



By downloading a free application to an iPhone or android phone, visitors are able to see rolling updates to the digital label after they leave the museum, or via twitter. Participants are also able to take part in the conversation online via the QRator site with comments appearing live within the museum.

Content currently covers two museums at UCL; The Grant Museum of Zoology and The Petrie Museum of Egyptology. he Grant Museum of Zoology is one of the oldest natural history collections in England, dating back to 1827. The collection comprises over 68,000 skeletal, taxidermy and wet specimens, covering the whole of the animal kingdom. Many of the species are now endangered or extinct including the Tasmanian tiger or thylacine, the quagga and the dodo. The Grant Museum is the only remaining university zoology museum in London.

The Museum will offer a continual programme of ‘Current Questions’ for visitors to engage in. UCL is taking the opportunity to rethink what a university museum can be; a place not simply for a passive experience but for conversation – a cultural laboratory for the meeting of minds. Positioning the Museum as a place of experimentation, dialogue and debate.


You can join the conversation by visiting either the Petrie or Grant Museum or by simply heading over to http://www.qrator.org all comments appear live on the iPad screens in the Museum and on Tales of Things.

Building 3D Agent-Based Models for Urban Systems: CASA Working Paper 161

By Posts No Comments

Number 161 in the every growing CASA Working Paper Series is Building 3D Agent-Based Models for Urban Systems by A.T. Crooks, A. Hudson-Smith and A Patel in a collaboration between George Mason University, United States of America and here at Centre for Advanced Spatial Analysis (CASA), University College London.

There is a growing interest in relating agent-based models to real- world locations by combining them with geographical information systems (GIS) which can be seen with the proliferation of geosimulation models in recent years. This coincides with the proliferation of digital data both in the two and three dimensions allowing one to construct detailed and extensive feature rich and highly visual 3D city models. This paper explores some of these developments in relation to our own initial work on building 3D geospatial agent-based models of urban systems and the technologies that allow for such models to be created. Furthermore, we highlight some techniques for the creation of 3D agent-based models and stress that such models are not a substitute to good models.

The intention of this paper is to explore the recent advances in computer technology, software and associated techniques that allow for the creation of 3D agent-based models which can be used to simulate various aspects of city life focusing on our own initial research of creating 3D cityscapes and 3D agent-based models. The remainder of this paper will therefore explore our attempts to use digital data to create feature rich 3D cityscapes (Section 2), discuss why such cityscapes are important for ABM (Section 3), before moving into how advances in computer hardware allow for the creation of 3D agent-based models (Section 4); we then briefly explore a potential application domain, that of pedestrian modelling (Section 5). Section 6 presents techniques which we are currently utilizing to create 3D agent-based models through various linking and coupling approaches along with advantage and disadvantages of each approach before a discussion is presented (Section 7).

RepRap + Marker Pen = Old School Printer

By 3d printer mod, etch a sketch, reprap One Comment

Here in CASA, University College London, we are currently waiting for the final part of our home made RepRap 3D Printer. Unfortunately it is a crucial part – the hot head that melts the plastic, allowing the printer to lay down layers of material and create objects.

While we are waiting, Steven Gray has modified the RepRap and replaced the hot head with a marker pen. This simple swap is actually an interesting concept, allowing the printer to draw:

In many ways its a high tech automated Etch A Sketch and for that we love it…
