New Paper: Using Gamification and Metaphor to Design a Mobility Platform for Commuters

Featured

Our paper on Using Gamification and Metaphor to Design a Mobility Platform for Commuters (McCall, Koenig and Kracheel) has now been published in The International Journal of Mobile Human-Computer Interaction.

Abstract: In this paper the authors explain the use of gamification as a way to optimize mobility patterns within a heavily congested European City. They explore this from two perspectives, first by outlining a gaming concept and secondly by explaining how the use of a mobility game that took place in two locations can be used to explore incentives and design issues.

Mediafire Vs Mega

These two services offer something quite similar in terms of cloud storage in that neither actually syncs the data on your computer; instead you upload data to a remote space and  download it again or share the links with others. This is quite different from Dropbox which syncs all or selected folders across devices. The following comparison looks at a paid MediaFire account vs a free Mega one. Not entirely fair but one way to do it.

Value for Money

No contest really Mega offers 50GB of free storage while Mediafire offers 10GB rising to 50GB if you sign people or use certain apps. If you want to upgrade then again Mega is cheaper per GB of space. Mediafire however offers to carry over unused bandwidth to the next month.

Speed

Here in Luxembourg Mediafire is by far the slowest cloud storage space I have used, upload speeds seem to be capped at 250kBps even on paid accounts, on the other hand Mega free is much faster even on free accounts. Download speed are also much better on Mega. Mediafire speed issues seem to apply regardless of which network I use.

Files

Free Mediafire accounts severely limit file size, Mega does not. Paid accounts on MedaFire limit files to 10GB. FIle uploading via websites in both cases worked well, although the MediaFire express App often appears unstable and buggy but it is in Beta. Right now Mega offers no official client apps although some unofficial ones are available on Android.

Features

Right now Mega offers little more than space and bandwidth if you pay. If you decide to pay on Mediafire you get some nice features which are not available on Mega (or only under limited conditions). Namely, one time file downloads, password protected files and the ability to download entire directories. The latter is only available to other registered users of Mega or if you share a folder specific public key (which may confuse some people). You can also set up a filedrop on Mediafire which lets people upload files to your account.

As noted MediaFire offers a desktop app, this has some nice features such as being able directly upload via the context menus on your computer or dragging and dropping files directly onto the pop-up uploader.

Security

On the face of it Mega wins throughout on this feature, however if you forget your password say goodbye to your data as you cannot get a new one! Mega claims that you and only the people you share your key with can decrypt your files.They also claim that as they do not store your key that your also have some degree of enhanced privacy. Assuming this all works as described then the service is far more secure than most other cloud providers, however there is some debate on how secure Mega really is.

Usability

Mega wins here on almost every level, while Medafire is hardly difficult to use it has some confusing ways of doing things. Also Mediafire makes uploading files in nested directory structures a very cumbersome task. Mega on the other hand makes this a doddle.

Extras

Mediafire offers an office environment called Zoho, however this is being phased out. Frankly that is a good thing but it will be interesting to see what will replace it. Due to the speed of Mega I also found it a good service for streaming movies on my Android tablet. Mediafire struggled a bit even on a small 10mb file – the Jewish Memorial one on this website.

Trust

Who would you trust with your data? Mega sadly has a far lower feeling of trust about it, mainly due to who is behind it (Kim Dotcom). MediaFire has a longer track record, has been used by reputable companies but like all sharing sites has perhaps unfairly been criticised for hosting pirated content uploaded by it’s users in the past.

Summary

If you need features then Mediafire is probably the platform for you. For speed and security Mega wins. I’d pick Mega if you want something simple for non-essential data, if you need to trust your cloud provider a bit more then pick Mediafire.

Review: Mega Cloud Service

The charming Kim Dotcom set up a new could service after his somewhat dodgy megaupload.com was shut down by the equally lovely US law enforcement authorities. Being the kind of chap he is he set up mega.co.nz which although still in beta offers many features you can find on other cloud services. I tried this out briefly today and have to say even the free accounts offer excellent upload and download speeds typically hitting 3-5MBps, which compares with a fraction of that for Dropbox, Google and Mediafire. Also the download speeds are equally impressive, typically in the 5MB plus category. So far this is by far the fastest “free” could service I have come across.

In terms of usability the website is a doddle and registering to use it is quick and simple. All the features are readily available with a mouse click and are easy to find and understand. As Mega uses a different security model to other platforms novice users may find the idea of encryption keys and link sharing with keys with other a little daunting. However, security is really the strong point of this platform. You can also upload entire directories quickly and easily.

My main worry about this site is who is behind it. For example would you trust a man who has an extradition warrant out against him in the US and is wanted there for various crimes? I am not sure if I really do but Mega does go out of it’s way to say that all data can only be decrypted and hence seen by it’s owner. That aside though, my main worry is whether they will be around in a year or two if law enforcement manages to catch up with Kim.

Mega is still in beta but there are a few Android clients available, otherwise you need to stick the Chrome browser. One word of warning if you forget your password you can kiss good bye to your data. Also like Mediafire there is no syncing of folders option. It is not a perfect service but you do get 50GB of space for free so who can complain at that? Upgrading to more storage and bandwidth is also surprisingly cheap with a 500GB plan along with 1TB of data per month being just €99.Also it is simple and above all fast and apparently secure.

Position Paper Submission Deadline: Monday, May 20th, 2013 (extended) Notification on Position Papers: Monday, June 10th, 2013 Workshop Date: Tuesday, August 27th, 2013

Using transportation technology (e.g., a car, plane, or traveling in public transportation) can be frustrating due to crowded streets, delays, and other travelers. Games & entertainment technology offer potential to resolve these negative user experiences. Frustration may lead to aggression and negative experiences resulting in irrational behaviors.

The workshop on Entertainment in Transportation will be a forum of multi-disciplinary discussion on how to combine research and design in both the entertainment and the transportation domain. The one-day workshop will include break-out sessions including the creation of entertainment and game concepts for future transportation. Contributions are invited from all areas of mobile HCI, games & entertainment, as well as transportation contexts such as cars, planes, buses, trains, or space ships.

Topics

———

Submissions are invited on (but not limited to) the following topics:

- Entertainment applications to reduce frustration, aggression and irrationality

- Game and entertainment application concepts, prototypes, and systems that suit a certain transportation context

- Studies on informing transportation entertainment system design

- Social aspects of gaming in the transportation domain, including passengers as well as personnel

- Interaction modalities for transportation entertainment

- Research addressing the social aspects of transportation entertainment

- Usage of transport context data as game input

Submissions

To participate authors please submit by May 20th, 2013 a position paper (no longer than 4 pages in the CHI extended abstract format) about their research containing the following aspects:

- The authors’ research perspective on entertainment and gaming in transportation and how to improve the situation of travelers through gaming and entertainment, including a description of a game and entertainment application (if applicable) or phenomenon they are working on or have studied.

- A reflection on the future challenges concerning entertainment in transportation that should be addressed by mobile HCI research.

- The way the authors aim at communicating their experience to the workshop participants (e.g., demo, interactive talk). Authors are invited to include an URL linking to digital documentation of a game, artifact, tool, service, project or study that offers a particular view on entertainment in transportation.

Submissions can, but do not have to be anonymized. Please submit your work via email to mobilehci2013@hciunit.org

Interactive presentations (such as demos) are highly encouraged and will be favored in the reviewing process.

We look forward to your contribution!

Well Done To Dundee University

Well done to Dundee University, my one time summer employer and where I did my BSc  is one of four Scottish Universities to be in the top 100 according to a global ranking of scientific performance conducted by Leiden University. The Scottish Universities in the top 100 are: St Andrews  (47th), Dundee (79th), Edinburgh (84th) and Aberdeen (91st). I don’t usually care too much for these rankings but being in the top 100 is pretty good, so well done to all of them. I hope that this will encourage companies to consider working more with Scottish  Universities and hence help to build on the talent of excellent researchers and graduates that are available there. More information about the story can be found at The Scotsman.

Also don’t forget where I work now, The University of Luxembourg, we may be comparatively new but offer the chance to work with leading researchers/professors in a range of domains. Also we have excellent links to local and international companies. Check out www.securityandtrust.lu for more info.

Review: Mediafire

Are you looking for an alternative to Dropbox or Google Drive? If so perhaps Mediafire is the answer.

To give you some background I have had enough of spending a lot on new computers when there are lots of good cloud storage and application solutions. Two obvious ones are Dropbox, which offers basic file storage and syncing across computers and Google Drive which offers storage, syncing and applications. Mediafire is slightly different and sits between these two as it does not sync files across computers, you basically upload them and share folders or files and download them if you or someone else wishes and like Google it also also comes with a range of office applications. Here is a quick summary of Mediafire and its relative advantages and disadvantages. Please note that the review is based on a paid pro subscription to Mediafire.

Advantages

  • Office suite is comparable to Google Docs in terms of basic features.
  • Avoids problem of auto syncing files which are very large, especially when on a slow network.
  • Files uploaded via the website are scanned for viruses, Dropbox does not offer this function.
  • Paid accounts support up to 10GB file sizes, free accounts limited to 200MB. Google also supports 10GB file sizes. Dropbox only limits file sizes to 300mb when they are uploaded via a web browser.
  • Free accounts have 10GB space as standard, paid accounts 100GB, plus you earn more for signing up more users.
  • 1TB of downloads per month with pro accounts, this can be rolled over. Great if you need to host files for use on your website or blog which may eat up bandwidth or space. Dropbox limits downloads per web link to 20GB per link per day for free accounts and 200GB per link per day for paid accounts.
  • Sharing files is very easy and the other party does not require an account or client in order to view them.
  • You can share files with others via Facebook and Twitter.
  • Files can be shared once via the one time download feature, with a set expiry date.
  • SSL upload encryption available.
  • Document collaboration is easy and other people do not need to sign up to  collaborate.
  • Client available for all major platforms including Android and Linux
  • You can provide an upload link to others or on your website so that people can easily send you files.
  • Reasonably fast download rate.
  • You can share files via a link or share them using a password, the latter is a very nice feature and avoid the need to force people to sign up for services.
  • The file uploading tool is generally easy to use and supports multiple uploads at once. You and other can also upload to your account via the web.
  • Pricing is comparable to Google, with the basic 100GB plan on both services costing €4.99 per month, this is half the price of Dropbox.
  • Fast and helpful customer support.
  • Other people can upload to a designated folder without them needing an account.

Disadvantages

  • Adverts and captchas are used on free accounts, although if the person hosting the account has paid then these are not displayed.
  • Very small file size limits for free accounts.
  • Slow upload rate, often around a 200KBPS on connections with much higher upload rates, which is far less than other services. If I am paying I expect far more than this quality of service.
  • No FTP upload
  • Except for the office suite this is not a collaboration environment, so unlike Dropbox people cannot edit the files you share with them then auto sync.
  • It is perceived as less trustworthy by many people as it is essentially a file sharing site with extra features. However, it has been used by many major companies.
  • Free accounts DO NOT offer long term storage so do not use them as a backup solution. Paid accounts do offer long term storage but again are not recommended as a backup solution.
  • Mac client doesn’t seem to work on all Intel Macs (well not mine anyway).
  • Office environment lacks integration with other third party applications.
  • Their website feels slower than Google or Dropbox.
  • The office applications do not seem to be very well integrated into the rest of the file storage options. For example I tried using images already stored on Mediafire inside a document and this was not possible; instead I had to upload them again or forage around for the url for the file on Mediafire.
  • It lacks basic file handling features when sharing with others, for example you cannot password protect then share a directory. Instead you can only password protect and share files.
  • You cannot create an archive of lots of files online then simply put the file immediately online without downloading it. This is annoying.
  • If people want to upload  files set in a specific  folder structure, this is not possible without you setting up the folder structure first then sending them individual links to each folder.

The biggest annoyance that I have come across so far is that you cannot password protect folders. This is a serious issue if like me you want to use it to share lots of large files but only with a select group of people. For this you must manually share a link for each file and set up a password. This means Mediafire in view is not a good medium for sharing lots of files in an ordered way, it is however good for sharing large single files.

In summary Mediafire is really just a file sharing site with an added office suite. It lacks the breadth and depth of features that you find with Google and does not automatically sync files. The latter is an advantage and disadvantage. If however you want a quick and easy way to send large files without forcing people to sign up to anything then it is a good choice. For sheer integration with other products and services Google is the clear winner. If however you you simply want a way to share large files without the privacy concerns attached to Google then Mediafire is a good option.

 

WordPress Hacking – Some Security Tips

I’d like to thank the hacker with a Ukrainian IP address that tried 10,001 times during 1 hr yesterday to hack into my blog – in the end though you did not succeed. There were a mere 20-30,000 other attempted hacks from a range of addresses; in all cases it was one particular page that was the target. As a result here are some tips for other WordPress users in order to restrict access to your blog to hackers.

  1. Create a new admin account with a random login nonsense login name and password that is classed as strong.  Your main admin account should not be called “admin” or anything similar.
  2. Ensure you have only one admin account, downgrade all others to something like author or contributor. Also change their passwords after completing this task.
  3. Install the “Limit Login Attempts Plugin” – this prevents the 10,000 or so logins from occurring and will lock down the admin account if required.
  4. The admin user should not write content, all content should by by one of the other classes of user.
  5. Install the Sucuri Sitecheck Scanner Free plugin and scan your blog frequently for malware.
  6. If you host your blog yourself you should probably also consider an SSL certificate to ensure logins not sent unencrypted. Contact your hosting provider for more information. I am also not an expert on installing these.

Prior to the attack I had been using multiple user accounts and also the Sucuri scanner (after  a scare last year). Overtime I am sure hackers will try again but I hope the 6 tips above will prove useful in preventing them from doing so also please do a search online for more exhaustive tips as I not a WordPress or security expert.

Cryptoparty at Konrad (Luxembourg) this Thursday

Having never been to one I am not sure exactly what it is and sadly I can’t go as I am out of the country. However, if you are interested in cryptography and digital privacy why not attend the party this week in Luxembourg. Some info from their email is below:

CryptoParty Lux 3, the third CryptoParty held in the Grand Duchy,will take place on Thursday, April 11th at 18:00 at Konrad Cafe, 7 Rue du Nord, Luxembourg.

“*CryptoParties* are a global movement in the interests of educating and
empowering people to protect their privacy in the digital domain.”

Normally I go to Konrad for it’s rather nice atmosphere and cheesecake.

Thatcher Dies

Lady ThatcherThe death of Margaret Thatcher, the Iron Lady!

If like me you lived through the Thatcher years in the UK then you will  probably have positive and negative memories. Personally I think she was the right person for the first four or five years of her Premiership and cut out much of the undue union influence and can’t do attitude that I am told existed in Britain at the time. However, her eleven years in power was more than enough with unemployment rising from 1m when she took office to little over 3m when she left. Also large parts of the UK were destroyed as many industries rather than being modernised were simply closed down. Many of these areas never fully recovered and it is often in these areas that the seeds of the so-called welfare dependency culture were sown. Due to the lack of meaningful industry she also planted the seeds of the import dependency that is now a cause for concern in the UK.

Being a school child at the time I cannot forget the lack of text books, leaky building (not enough money was often available to do the repairs) and general decline of education – the  massive exam reforms were chaotic although perhaps well intentioned. She can be said though to have revolutionised the university sector by removing the often a false barrier between universities and polytechnics – something scorned upon by many until this day. She also was was instrumental in making the City of London what it is today – but I am not sure if this is a good thing. Indeed it was so successful that comedian Harry Enfield is said to have been surprised at the number of stupid people earning even more stupid salaries that worked there that he created the character “Time nice but Dim”. A typical Tory boy with little between the ears except a desire for cash, women and partying although in the end too stupid to actually be nasty or harmful.

Other less pleasant sides included tea and cakes with General Pinochet and some murky tactics being used against suspected terrorists in Northern Ireland. In both of these cases though they came down to need and in the case of Northern Ireland a desire to bring about an end to the mindless violence that had ensued. We should also not forget that the IRA did try to kill the entire British Cabinet in a bomb blast, thankfully they failed and she rightfully took the conference stage a few hours later to say they had  been defeated. Even in the face of a near death experience she remained the Iron Lady.

If there is one good thing that can be said about her Premiership it was that women were at last allowed to reach the top parts of British democracy. It is perhaps though her quote below which will be remembered most as she apparently said there is no such thing as society, she was however misquoted as you can see.

“I think we have gone through a period when too many children and people have been given to understand ‘I have a problem, it is the government’s job to cope with it!’ or ‘I have a problem, I will go and get a grant to cope with it!’; ‘I am homeless, the government must house me!’ and so they are casting their problems on society and who is society?

“There is no such thing! There are individual men and women and there are families, and no government can do anything except through people and people look to themselves first.

“It is our duty to look after ourselves and then also to help look after our neighbour and life is a reciprocal business and people have got the entitlements too much in mind without the obligations.”

In summary no doubt she had a huge influence on the UK but in many ways we are only now only beginning to fully understand the implications of her often overly simplified policies have on long-term social cohesion. In the end she strengthened the rich and more or less left the country divided and driven by one thing: greed.

In any event rest in peace and my thoughts to her family.
