Help Making Location Based Services Relevant

I've been reviewing the recent literature related to location based services and locative media and came across an incredibly useful article for those building or refining such apps. The article, Criteria of geographic relevance: An experimental study, will be published soon in the International Journal of Geographical Information Science (but is freely available in a pre-print version). The authors, Stefano De Sabbata and Tumasch Reichenbacher are experts in geographic relevance, mobile information retrieval, and location based services.

It's worth reading their entire article, but they include a summary table that lists all the types of information relevance and ones specifically applicable to mobile, geolocative functionality. Relevance, in this sense, refers to the degree to which information returned by a digital service satisfies various user needs and desires. (Read more about information relevance on Wikipedia).

In my efforts to keep updated on location based services, I've noticed that many apps focus on the relevance criterion of proximity to the neglect of all other (possibly more pertinent) factors. De Sabbata and Reichenbacher offer an invaluable list of other factors that developers should consider for more effective and engaging user experiences. Even better, their work is based on actual user studies.

Here is their table of relevance criteria, based on the classes of: properties (of the object), geography, information, and presentation (of the end result, to the user).

For details on a particular concept, the article has useful explanations.

Although location based services are, by definition, preoccupied with location (i.e. spatial proximity) this list offers guidance on other criteria to add that would greatly improve current locative apps.

This list seems definitive to me, but if anyone has a criteria to add or refine, I'd love to hear it below.

Canada's Walk of Fame - Needs Digital Footprints

Since Canada's Walk of Fame started in Toronto's entertainment district in 1998, I thought it was a great way to recognize the accomplishments of notable Canadians. Canadians don't often value their history and culture and the Walk brings prominence to these contributions.

As a physical manifestation of Canadian culture, Canada's Walk of Fame is definitely lacking in digital footprints. There are no people from the Canada's digital media section (i.e. this includes gaming, the Web, mobility, etc). I think this is the year that someone from digital media be inducted!

Suitable category are "Science and Innovation" (Alexander Graham Bell is the only inductee in this category) and  "Visual Arts" category (only Lynn Johnston and Jean-Paul Riopelle).

Only a handful of people are inducted every year and one has to be born in Canada or spent their formative years here and been working in the field for at least 10 years to qualify.

The Walk of Fame encourages submissions and it's really quick and easy (you also get a chance to win a trip to Toronto and tickets to the gala induction ceremony). So I'm starting a campaign to get a Canadian in digital media inducted this year.

A lot of people from my Who's Who in Canadian Digital Media and Technology don't qualify as they haven't met the 10-year career mark. But here are some people that I think would be great nominees:
There are lots more. I'd love to hear here if anyone has any specific suggestions - or would like to start a group effort to get one person in particular nominated.

Nominations close April 30, 2012 - so nominate someone today.

Location-based Services On the Road

Test Driving GPS Navigation Devices
I don't own or often even use a car, so I haven't had the opportunity to use in-car GPS navigation devices. As my research focuses on location-based services, it's easy to focus on the hype generated by mobile apps, and forget the popular workhouse of the LBS industry.

So on a recent trip to Hawaii and wanting to explore more of the islands than feasible with public transit or tour buses, I was eager to try out GPS devices when I rented a car.  I figured it would be a great way to try out this tech and make my travels easier. I sure got to know  more about the tech, but I think the GPS device resulted in more problems than help. Although I used the same product, from what I've read and encountered, it sounds like my experience is not atypical.

What I liked about the GPS navigation device
:
  • basic functionality is easy to use
  • accuracy of positioning and its map interface
  • we also got some unrequested but appreciated information on attractions near us that gave historical and cultural commentary (although we didn't want it again when we passed by it on the return trip)
What I didn't like:
  • told us to turn the wrong way down one-way street and drive into an active volcano
  • doesn't recognize unofficial roads (e.g. national parks, mall parking lots, etc)
  • voice is often indecipherable
  • directions not given in enough advance (e.g. tells us to turn while almost parallel to the road)
  • not offer enough detail if zoom out (e.g. place names and roads)
  • doesn't remember destination if turn device off (e.g. to get something to eat)
  • can't add sub-destinations (e.g. post office, restaurant)
  • location finder very limited and many attractions and long-term businesses not listed
  • ultimately it was wrong or bizarre so many times that I just couldn't trust it
Some of these problems could be rectified by gaining familiarity with the interface and features of the device or possibly with another product.

Overall, I was disappointed with GPS navigation device for two main reasons: 1) it doesn't replace trip planning and way finding with print maps and 2) it isn't easy to use enough to use that a driver could safely do it on their own.

We had similar problems with other sources of automated way-finding on the trip. We also printed off AAA/CAA customized maps and detailed driving directions ("Triptiks") from their website. The TripTiks seemed like they would get one from point A to point B but they took bizarre and difficult routes. Without any explanations provided for why a seemingly odd route was chosen or even if there was a reason, their routes seemed unnecessary complicated and longer.

I've also encountered the same problem with Google Maps. For example, when trying to get directions to my place, it has one going blocks out of the way to avoid a left turn (perfectly legal and easy).

So my hopes of an automated solution to replace the dreaded navigation seems a ways off.

Smartphone LBS On the Road
I did find it enjoyable and useful to use LBS on my smartphone while on my travels. I've always feared the roaming charges of my mobile carrier plan, so I've never used Foursquare (my LBS of choice) outside of my home town.

I checked into a bunch of different places and looked up reviews and deals in various places. I also posted my location and comments from foursquare to my Facebook account.

It was great to share the main sites and my experiences - more so since the places were so new and different (it also helped me get a bunch of badges, not that I care about such gimmicks - okay, I kinda do).  Looking back on my check-ins, it was a great travel log.

I decided to experiment this trip and pay the costs to try things out, but my bill hasn't yet come, so my fondness may soon enough turn sour.

Benefits of Geotargetted Information

Location-based services (LBS) and locative media have garnered a lot of attention - not least of which will be the focus of my dissertation. But the possible benefits beyond increased marketing opportunities has rarely been discussed or studied. Here's some of what I've come up with so far:

Recent studies are showing societal benefits for place-related information accessed via mobile devices (i.e. geotargetted information). In a Pew study, How mobile devices are changing community information environments, 65% of survey respondents with a mobile device feel it is now easier to keep up with local, community information compared with 47% for non-mobile users.

Pew also found people who accessed local news via their mobile were more likely than other adults to feel they can have a substantial impact on their community (35% vs. 27%). According to a Microsoft survey, Location Based Services Usage and Perceptions, in US, UK, Canada, Germany, and Japan, 50% of smartphone users are using LBS. The leading uses were found to be information seeking, specifically for navigation and way-finding and geotargetted weather forecasts and local news. The survey also found 94% of respondents said they find LBS to be a valuable aid.

It is my belief that geotargetted information can improve our familiarity with places and foster a positive sense of place. Sense of place has been studied in various ways in various disciplines and found to have numerous benefits. From a social perspective, sense has been found to lead to place attachment (Morgan, 2010; Williamson & Roberts, 2010). Place attachment is seen as not only central to one’s identity (Morgan, 2010) but it also assists in the formation of a sense of community (Williams, Kitchen, DeMiglio, Eyles, et al., 2010) and aids people in caring for and protecting their urban environment (Jacobs, 1992). A better understanding of how people form sense of place and the role of  LBS is useful in numerous academic and applied contexts.

From a design perspective, human-computer interaction researchers are beginning to examine the role of SOP and mobile technology (Lentini & Decortis, 2010) and offer tentative interface and interaction recommendations. Tourism and recreation scholars and practitioners can benefit from understanding how visitors come to know and experience travel destinations and their use of LBS so as to improve marketing efforts and visitor satisfaction. This area is also of interest in the fields of urban studies, architecture, and geography to create more responsive land use, buildings, and civic spaces and improve communication resources.. Museologists can benefit from learning how LBS can be used to improve interpretation efforts, patron experience, and conservation efforts.

For librarians, understanding the value of geographically relevant information can be a means of demonstrating the importance of adding georeferenced metadata or mechanisms to collections. Local studies librarianship, the field of study that addresses collecting, preserving, and providing access to the local history and news within the vicinity of a given library branch, can also benefit from this research. Reid & Macafee (2007) believe new technology can move local studies librarianship beyond traditional notions of offering clippings of local newspapers and history discussions to extending their services to new and larger audiences and more effectively engage the community.

There are additional implications to examining LBS as a method of communication and identity performance (Phillips, 201). Finally, there are policy considerations (Phillips, 2011) pertaining to privacy and accessibility that can best be addressed through a deeper understanding of the underlying user behaviour and technology.

I've only begun to look at this and would appreciate any thoughts or publications on this topic...

Tips for Conference Posters

This week I attended iConference 2012 and they had an impressive and extensive display of academic posters. Of all the conferences I've been to, I found this conference had the most effective posters. As the conference was for information schools (iSchools), it is not surprising that presenters would know how to effectively display information visually and succinctly.

While viewing the posters, I made mental notes of what was effective and what was not:

Poster Design
  • Posters displayed as mini research papers (e.g. with sections for abstract, intro, lit review, method, findings, conclusions, references) were overwhelming too read and dull  - I think this format is best for the proceedings publication but the poster itself should consider the demands of the visual medium
  • Standard graphic design principles apply (e.g. font, colour, spacing, whitespace, etc.)
  • Consider the unique design needs for posters - e.g. large font size, easy to read, unique, etc.
  • Colour is essential to make the poster appealing and attract attention - not too many though more than one colour is needed but probably not more than 3-4 (including shades)
  • Limit content to 2-3 points
  • Key message should be in a call-out and placed prominently - it's better when it's short and not a full abstract
  • Images should not be eye candy, but reflect the content of the study
  • Include your contact information - i.e. email address and website (I was surprised by how many people did not include this)
  • References - lots of posters didn't have these and the ones that did it took up a lot of space that wasn't useful for attendees. If they can be omitted or referred to a website for them, I think the space can be much better used
  • Moratorium needed on word clouds - I estimate that a third of posters included them. They seem trite now and aren't an effective way (e.g. legibility issues) to present main themes
Supporting Material
Take-aways for attendees are a great way to ensure that people will actually follow-up with you or read the work in more detail.  As posters are available for display outside of the official presentation hours, it is a great idea to have them pinned near or on your poster (bring extra pins for these). Take-aways can include:
  • Print-out of the poster (full colour is better)
  • Business cards
  • Postcards of the project
Presentation
  • One of the main points of posters is to provide a means to connect with others interested in your work, so it's important to actually be present during the designated poster presentations (surprisingly at an iConference's poster session some presenters were not there for the entire two hours)
  • Show up early, I went half an hour before the designated time and there were a fair number of people who were also there early - this is a great time to stand out and talk to people before the hoard  arrives
Miscellany
  •  Consider adding interactivity or multimedia to your poster as a way to standout and offer supporting content - this is particularly effective outside of the official session presentation as people have more time (and quiet) to spend on the posters.  Two techniques I found effective at iConference, were push-button audio clips of interview excerpts and tablets running a demo of the project software.
The University of Leichester has a really good, in-depth tutorial on posters and Colorado State University has a useful poster guide

I'm hoping to present a poster in the next year, so I'd love to hear other people's tips here!
