There is something in the physical presence of book that is pleasurable. Receiving the copy of Introducing Human Geographies was special, as I have contributed a chapter about Geographic Information Systems to the ‘cartographies’ section.
It might be a response to Ron Johnston critique of Human Geography textbooks or a decision by the editors to extend the content of the book, but the book now contains three chapters that deal with maps and GIS. The contributions are the ‘Power of maps’ by Jeremy Crampton, a chapter about ‘Geographical information systems’ by me, and ‘Counter geographies’ by Wen Lin. To some extent, we’ve coordinated the writing, as this is a textbook for undergraduates in geography and we wanted to have a coherent message.
In my chapter I have covered both the quantitative/spatial science face of GIS, as well as the critical/participatory one. As the introduction to the section describes:
“Chapter 14 focuses on the place of Geographical Information Systems (GIS) within contemporary mapping. A GIS involves the representation of geographies in digital computers. … GIS is now a widespread and varied form of mapping, both within the academy and beyond. In the chapter, he speaks to that variety by considering the use of GIS both within practices such as location planning, where it is underpinned by the intellectual paradigm of spatial science and quantitative data, and within emergent fields of ‘critical’ and ‘qualitative GIS’, where GIS could be focused on representing the experiences of marginalized groups of people, for example. Generally, Muki argues against the equation of GIS with only one sort of Human Geography, showing how it can be used as a technology within various kinds of research. More specifically, his account shows how current work is pursuing those options through careful consideration of both the wider issues of power and representation present in mapping and the detailed, technical and scientific challenges within GIS development.”

An interview by Prof Anthony Costello of UCL Institute of Global Health, discussing the growth in citizen science today.
During the symposium “The Future of PGIS: Learning from Practice?” which was held at ITC-University of Twente, 26 June 2013, I gave a talk titled ‘Keeping the spirit alive’ – preservations of participatory GIS values in the Geoweb, which explored what was are the important values in participatory GIS and how they translate to the Geoweb, Volunteered Geographic Information and current interests in crowdsourcing. You can watch the talk below.

The term ‘Citizen Science’ is clearly gaining more recognition and use. It is now get mentioned in radio and television broadcasts, social media channels as well as conferences and workshops. Some of the clearer signs for the growing attention include discussion of citizen science in policy oriented conferences such as UNESCO’s World Summit on Information Society (WSIS+10) review meeting discussion papers (see page ), or the Eye on Earth users conference (see the talks here) or the launch of the European Citizen Science Association in the recent EU Green Week conference.
Another aspect of the expanding world of citizen science is the emerging questions from those who are involved in such projects or study them about the efficacy of the term. As is very common with general terms, some reflections on the accuracy of the term are coming to the fore – so Rick Bonney and colleagues suggest to use ‘Public Participation in Scientific Research‘ (significantly, Bonney was the first to use ‘Citizen Science’ in 1995); Francois Grey coined Citizen Cyberscience to describe projects that are dependent on the Internet; recently Chris Lintott discussed some doubts about the term in the context of Zooniverse; and Katherine Mathieson asks if Citizen Science is just a passing fad. In our own group, there are also questions about the correct terminology, with Cindy Regalado suggestions to focus on ‘Publicly Initiated Scientific Research (PIScR)‘, and discussion on the meaning of ‘Extreme Citizen Science‘.
One way to explore what is going on is to consider the evolution of the ‘hype’ around citizen science through ‘Gartner’s Hype Cycle‘ which can be seen as a way to consider the way technologies are being adopted in a world of rapid communication and inflated expectations from technologies. leaving aside Gartner own hype, the story that the model is trying to tell is that once a new approach (technology) emerges because it is possible or someone reconfigured existing elements and claim that it’s a new thing (e.g. Web 2.0), it will go through a rapid growth in terms of attention and publicity. This will go on until it reaches the ‘peak of inflated expectations’ where the expectations from the technology are unrealistic (e.g. that it will revolutionize the way we use our fridges). This must follow by a slump, as more and more failures come to light and the promises are not fulfilled. At this stage, the disillusionment is so deep that even the useful aspects of the technology are forgotten. However, if it passes this stage, then after the realisation of what is possible, the technology is integrated into everyday life and practices and being used productively.
So does the hype cycle apply to citizen science?
If we look at Gartner cycle from last September, Crowdsourcing is near the ‘peak of inflated expectations’ and some descriptions of citizen science as scientific crowdsourcing clearly match the same mindset.
There is a growing evidence of academic researchers entering citizen science out of opportunism, without paying attention to the commitment and work that is require to carry out such projects. With some, it seems like that they decided that they can also join in because someone around know how to make an app for smartphones or a website that will work like Galaxy Zoo (failing to notice the need all the social aspects that Arfon Smith highlights in his talks). When you look around at the emerging projects, you can start guessing which projects will succeed or fail by looking at the expertise and approach that the people behind it take.
Another cause of concern are the expectations that I noticed in the more policy oriented events about the ability of citizen science to solve all sort of issues – from raising awareness to behaviour change with limited professional involvement, or that it will reduce the resources that are needed for activities such as environmental monitoring, but without an understanding that significant sustained investment is required – community coordinator, technical support and other aspects are needed here just as much. This concern is heightened by statements that promote citizen science as a mechanism to reduce the costs of research, creating a source of free labour etc.
On the other hand, it can be argued that the hype cycle doesn’t apply to citizen science because of history. Citizen science existed for many years, as Caren Cooper describe in her blog posts. Therefore, conceptualising it as a new technology is wrong as there are already mechanisms, practices and institutions to support it.
In addition, and unlike the technologies that are on Gartner chart, academic projects within which citizen science happen benefit from access to what is sometime termed patient capital without expectations for quick returns on investment. Even with the increasing expectations of research funding bodies for explanations on how the research will lead to an impact on wider society, they have no expectations that the impact will be immediate (5-10 years is usually fine) and funding come in chunks that cover 3-5 years, which provides the breathing space to overcome the ‘through of disillusionment’ that is likely to happen within the technology sector regarding crowdsourcing.
And yet, I would guess that citizen science will suffer some examples of disillusionment from badly designed and executed projects – to get these projects right you need to have a combination of domain knowledge in the specific scientific discipline, science communication to tell the story in an accessible way, technical ability to build mobile and web infrastructure, understanding of user interaction and user experience to to build an engaging interfaces, community management ability to nurture and develop your communities and we can add further skills to the list (e.g. if you want gamification elements, you need experts in games and not to do it amateurishly). In short, it need to be taken seriously, with careful considerations and design. This is not a call for gatekeepers , more a realisation that the successful projects and groups are stating similar things.
Which bring us back to the issue of the definition of citizen science and terminology. I have been following terminology arguments in my own discipline for over 20 years. I have seen people arguing about a data storage format for GIS and should it be raster or vector (answer: it doesn’t matter). Or arguing if GIS is tool or science. Or unhappy with Geographic Information Science and resolutely calling it geoinformation, geoinformatics etc. Even in the minute sub-discipline that deals with participation and computerised maps that are arguments about Public Participation GIS (PPGIS) or Participatory GIS (PGIS). Most recently, we are debating the right term for mass-contribution of geographic information as volunteered geographic information (VGI), Crowdsourced geographic information or user-generated geographic information.
It’s not that terminology and precision in definition is not useful, on the contrary. However, I’ve noticed that in most cases the more inclusive and, importantly, vague and broad church definition won the day. Broad terminologies, especially when they are evocative (such as citizen science), are especially powerful. They convey a good message and are therefore useful. As long as we don’t try to force a canonical definition and allow people to decide what they include in the term and express clearly why what they are doing is falling within citizen science, it should be fine. Some broad principles are useful and will help all those that are committed to working in this area to sail through the hype cycle safely.

CHI 2013 and GeoHCI workshop highlighted to me the importance of understanding media for maps. During CHI, the ‘Paper Tab’ demonstration used E-Ink displays to demonstrate multiple displays interaction. I found the interactions non-intuitive and not mapping very well to what you would expect to do with paper, so a source for confusion – especially when they will eventually be mixed with papers on a desk. Anyhow, it is an interesting exploration.
E Ink displays are very interesting in terms of the potential use for mapping. The image below shows one of the early prototypes of maps that are designed specifically for the Kindle, or, more accurately, to the E Ink technology that is at heart of the Kindle. From a point of view of usability of geographical information technologies, the E Ink is especially interesting. There are several reasons for that.
First, the resolution of the Kindle display is especially high (close to 170 Pixels Per Inch) when the size of screen is considered. The Apple Retina display provide even better resolution and in colour and that makes maps on the iPad also interesting, as they are starting to get closer to the resolution that we are familiar with from paper maps (which is usually between 600 and 1200 Dot Per Inch). The reason that resolution matter especially when displaying maps, because the users need to see the context of the location that they are exploring. Think of the physiology of scanning the map, and the fact that capturing more information in one screen can help in understanding the relationships of different features. Notice that when the resolution is high but the screen area is limited (for example the screen of a smartphone) the limitations on the area that is displayed are quite severe and that reduce the usability of the map – scrolling require you to maintain in your memory where you came from.
Secondly, E Ink can be easily read even in direct sunlight because they are reflective and do not use backlight. This make them very useful for outdoor use, while other displays don’t do that very well.
Thirdly, they use less energy and can be used for long term display of the map while using it as a reference, whereas with most active displays (e.g. smartphone) continuous use will cause a rapid battery drain.
On the downside, E Ink refresh rates are slow, and they are more suitable for static display and not for dynamic and interactive display.
During the summer of 2011 and 2012, several MSc students at UCL explore the potential of E Ink for mapping in detail. Nat Evatt (who’s map is shown above) worked on the cartographic representation and shown that it is possible to create highly detailed and readable maps even with the limitation of 16 levels of grey that are available. The surprising aspects that he found is that while some maps are available in the Amazon Kindle store (the most likely place for e-book maps), it looks like the maps where just converted to shades of grey without careful attention to the device, which reduce their usability.
The work of Bing Cui and Xiaoyan Yu (in a case of collaboration between MSc students at UCLIC and GIScience) included survey in the field (luckily on a fairly sunny day near the Tower of London) and they explored which scales work best in terms of navigation and readability. The work shows that maps at scale of 1:4000 are effective – and considering that with E Ink the best user experience is when the number of refreshes are minimised that could be a useful guideline for e-book map designers.

The UCL Urban Laboratory is a cross-disciplinary initiative that links various research interest in urban issues, from infrastructure to the way they are expressed in art, films and photography. The Urban Laboratory has just published its first Urban Pamphleteer which aim to ‘confront key contemporary urban questions from diverse perspectives. Written in a direct and accessible tone, the intention of these pamphlets is to draw on the history of radical pamphleteering to stimulate debate and instigate change.’
My contribution to the first pamphleteer, which focused on ‘Future & Smart Cities’ is dealing with the balance between technology companies, engineers and scientists and the values, needs and wishes of the wider society. In particular, I suggest the potential of citizen science in opening up some of the black boxes of smart cities to wider societal control. Here are the opening and the closing paragraphs of my text, titled Beyond quantification: we need a meaningful smart city:
‘When approaching the issue of Smart Cities, there is a need to discuss the underlying assumptions at the basis of Smart Cities and challenge the prevailing thought that only efficiency and productivity are the most important values. We need to ensure that human and environmental values are taken into account in the design and implementation of systems that will influence the way cities operate…
…Although these Citizen Science approaches can potentially develop new avenues for discussing alternatives to the efficiency and productivity logic of Smart Cities, we cannot absolve those with most resources and knowledge from responsibility. There is an urgent need to ensure that the development and use of the Smart Cities technologies that are created is open to democratic and societal control, and that they are not being developed only because the technologists and scientists think that they are possible.’
The pamphleteer is not too long – 32 pages – and include many thought-provoking pieces from researchers in Geography, Environmental Engineering, Architecture, Computer Science and Art. It can be downloaded here.
As I’ve noted in the previous post, I have just attended CHI (Computer-Human Interaction) conference for the first time. It’s a fairly big conference, with over 3000 participants, multiple tracks that evolved over the 30 years that CHI have been going, including the familiar paper presentations, panels, posters and courses, but also the less familiar ‘interactivity areas’, various student competitions, alt.CHI or Special Interest Groups meetings. It’s all fairly daunting even with all my existing experience in academic conferences. During the GeoHCI workshop I have discovered the MyCHI application, which helps in identifying interesting papers and sessions (including social recommendations) and setting up a conference schedule from these papers. It is a useful and effective app that I used throughout the conference (and wish that something similar can be made available in other large conferences, such as the AAG annual meeting).
With MyCHI in hand, while the fog started to lift and I could see a way through the programme, the trepidation about the relevance of CHI to my interests remained and even somewhat increased, after a quick search of the words ‘geog’,'marginal’,'disadvantage’ returned nothing. The conference video preview (below) also made me somewhat uncomfortable. I have a general cautious approach to the understanding and development of digital technologies, and a strong dislike to the breathless excitement from new innovations that are not necessarily making the world a better place.
Luckily, after few more attempts I have found papers about ‘environment’, ‘development’ and ‘sustainability’. Moreover, I discovered the special interest groups (SIG) that are dedicated to HCI for Development (HCI4D) and HCI for Sustainability and the programme started to build up. The sessions of these two SIGs were an excellent occasion to meet other people who are active in similar topics, and even to learn about the fascinating concept of ‘Collapse Informatics‘ which is clearly inspired by Jared Diamond book and explores “the study, design, and development of sociotechnical systems in the abundant present for use in a future of scarcity“.
Beyond the discussions, meeting people with shared interests and seeing that there is a scope within CHI to technology analysis and development that matches my approach, several papers and sessions were especially memorable. The studies by Elaine Massung an colleagues about community activism in encouraging shops to close the doors (and therefore waste less heating energy) and Kate Starbird on the use of social media in passing information between first responders during the Haiti earthquake, explored how volunteered, ‘crowd’ information can be used in crisis and environmental activism.
Other valuable papers in the area of HCI for development and sustainability include the excellent longitudinal study by Susan Wyche and Laura Murphy on the way mobile charging technology is used in Kenya , a study by Adrian Clear and colleagues about energy use and cooking practices of university students in Lancaster, a longitudinal study of responses to indoor air pollution monitoring by Sunyoung Kim and colleagues, and an interesting study of 8-bit, $10 computers that are common in many countries across the world by Derek Lomas and colleagues.
The ‘CHI at the Barricades – an activist agenda?‘ was one of the high points of the conference, with a showcase of the ways in which researchers in HCI can take a more active role in their research and lead to social or environmental change, and considering how the role of interactions in enabling or promoting such changes can be used to achieve positive outcomes. The discussions that followed the short interventions from the panel covered issues from accessibility to ethics to ways of acting and leading changes. Interestingly, while some presenters were comfortable with their activist role, the term ‘action-research’ was not mentioned. It was also illuminating to hear Ben Shneiderman emphasising his view that HCI is about representing and empowering the people who use the technologies that are being developed. His call for ‘activist HCI’ provides a way to interpret ‘universal usability‘ as an ethical and moral imperative.
So despite the early concerned, CHI was a conference worth attending and the specific jargon of CHI now seem more understandable. I wish that there was on the conference website a big sign ‘new to CHI? Start here…’
