Editor's note: A few weeks ago Richard outlined that the A&Mi team would be testing out at . Here's the promised update on how things went - PM.

'...If you're taking someone who's not your boyfriend or girlfriend and you haven't told them that you have tickets, then don't check in...'
Radio 1 DJ Scott Mills on his show the day before the event.

The concept was to see if the audience at a live broadcast event would want to share their experience of what was happening on the stage in front of them with their social network. To make it even more interesting we'd be doing it in the technically challenging location of an airfield on the outskirts of Carlisle.

The challenge I was set was to find an engaging model for those at the event to link up with those who weren't and in essence to create a conversation around a piece of 主播大秀 content, in this case the Radio 1 Big Weekend festival.

As I arrived in Carlisle, my blood pressure rose on finding out that we had no connectivity via at our hotel at all...even when standing on one leg with my phone in the air. Thankfully the coverage on site was much better due to the installation of three mobile operator's 3G boosters.

I then remembered that we had another location quirk to overcome. Temporary 3G boosters do not have any lat/long coordinates associated with them. As we had developed the prototype to detect a user's location firstly via WiFi, then 3G cell triangulation and finally a device's own . I discovered that using 3G placed me over a mile away from my actual location.

As WiFi was not an option due to its limitations of concurrent users, it was down to my device GPS only. From conversations with users later on we realised that many people do not have GPS enabled all of the time due to its high power consumption.

After running some tests on the Friday and Saturday morning I realised that the page load time was a little slow due to the limited connectivity.

On some of the pages the key feature buttons were displaying before the whole page had finished loading which meant that people were pressing the 'check in here' button before all of the background location and sign in checks had been done. This then resulted in an error displaying even though a user had successfully checked in.

One way round this would have been to offer some bespoke content to get the audience to go to the prototype site prior to the event, so that the site could be cached on their phone thus reducing the load time when they got onsite...

The prototype was a 'mash-up' of 主播大秀 content feeds from our artist pages and Facebook as the publishing tool which resulted in a more complex technical design than we had originally hoped. The number of background checks to and the phones location caused some problems with the prototype such as the number of calls to the 'Places' API.

The success of the product early on the Saturday meant that the Facebook system thought we were spamming it. We were innovating with a live service which often has its unexpected challenges. Luckily we had support from and Facebook during the weekend so we did some live hacks, sorry 'updates', to iron out the issues we faced.

After a tense few hours working through some complex issues with the product and Facebook, we were back up and running smoothly. By around 5pm we saw the number of errors reduced and the check ins were on the up.

Thankfully, we had a different audience every day so we could start afresh. This is one reason why we used as a testing ground.

The next challenge was to find out what the audience thought about the product and the check in prototype as a whole. Did they get it? Was the reward of saying "I'm watching Lady Gaga" a good enough reason and could they see the difference in what we were doing to what other location based services did?

A research company carried out some qualitative research on the Sunday and some of the audience used a video diary to feedback what they thought.

At we are testing a new mobile feature that allows the audience to say "I'm here now" to their friends while watching their favourite artists throughout the day. The key thing is that they have to be present at a stage to check in.

So why are we doing this? This is an experiment to help the 主播大秀 explore around Check Ins and ask whether the technology can enhance our audiences' experience of similar events. By using the latest mobile location technology, and a bit of web design, we've built a prototype that let's our audience share the experience with their family and friends in a way in which they're used to. We decided to use Facebook Places because we believe most of the audience at the event will have an account.

At the 主播大秀 I run a number of social media projects and we've been wanting to do something involving the audience at festivals and listeners at home for quite a while. The challenge I set myself here was to find a new and engaging way for the 主播大秀 to encourage users to share their festival experiences, good or bad, with the wider world.

The 'Check In' experiment is my proposed solution. It was initially developed on a beer mat in December 2010 but after a late night or two and hard work from the team it was delivered on time. It will only be available to smartphone users with Facebook accounts, attending Radio 1's Big Weekend in Carlisle. Participants are able to share a number of things: which stage they're at, who they're listening to and what they think of the performance. This information will be shared with friends via the user's Facebook newsfeed.

Here's how it works:

The site asks users to verify their location by either checking their cell or using their . Privacy has been a concern on this project from the outset. We have taken great care in making sure that this site is an example of how to be safe whilst using Check Ins. By default, our site only publishes information and comments to a user's friends via their .

The prototypes database tells us how many people have checked into a performance and how many times they have checked in but the 主播大秀 does not hold any users' personal data. The system is completely anonymous, so while we can visualise the numbers of users we're unable to tell who they are. We also signpost that users can amend to decide how and with whom they share this information. As Radio 1's Big Weekend is a ticketed event, we felt that this would be the perfect choice for an experiment of this kind as it reduce concerns of the audience sharing where they are. We also felt that this was a great opportunity to raise awareness with our audience of location privacy. The way we are doing this is to promote how to stay safe on-line as well as providing top tips for anyone using location based services.

From the start, allowing users to say where they were as one of our prototypes was going to be an interesting shift in what we do. We defined a set of criteria to be evaluated and we are carrying out three stages of audience research focusing on qualitative research at the event with 6 young people. They'll be given phones for the day and asked to evaluate the experiment and the promotion.

This has been a truly challenging and thrilling project to work on with some great people but there'll be no rest until the final evaluation in a few weeks. I'll be doing a further post after next weekend with details of how it went. - RM

NB: This is an experiment so unfortunately we cannot make it work on all mobiles. If you are attending then your handset will need to have location detection enabled and a browser that can handle HTML5 web code. For example: the iPhone 3GS, iPhone 4, Sony Ericsson X10, Samsung Galaxy and Galaxy S, HTC Desire, Desire HD and Nexus One, and any phones using Android 2.1 operating system and above (excluding tablets and small-screen devices such as Samsung Galaxy Mini, Sony Experia X10 Mini and HTC Wildfire).

The is tied up, done and dusted... and was my highlight. It was emotional, it had some new music (to my ears at least) bringing together hundreds of millions of people all listening and enjoying the same moment together. Whether you attended in person outside the Abbey, Buckingham Palace or lining the route, or whether like most of us, you joined in via the TV, radio or internet it was about people coming together to celebrate a single live event.

In part the music was powerful because we all knew it the came from the personal choices that the happy couple had made and it meant something deeply to them. An intriguing insight because, if you are married, you know as with many other wedding decisions, had probably been hard fought.

Only 40,000 people can attend , making their own choices on the day, which stage to wander to and which artists to see. The rest of the audience can obviously listen on the radio, watch all the stages live online or navigate through the 60+ videos available later on. Our research tells us that they are normally seeking out what they know they already like.

Personal choices in music are what make breathe. The expert view (i.e. our DJs' passion about a tune), combined with a populist, audience viewpoint (charts, sales, audience research and comment) - make Radio 1 in 2011, I hope, just as valuable as ever. It represents the friend (our DJ) and the family (the listeners) coming together. Interestingly, it is reported that these are still the most popular ways in which music choices are decided. Family. Friends. Radio.

Big Weekend gives our DJs a place to curate music in the digital space as well as on air. We are starting with six of our DJs at and their selection of photos, video and favourite artists that mean something to them. Our users' choices will also be reflected for the first time on the site via rankings of the 'Most Viewed' and 'Most Shared' artists.

Encouraging presenters and audiences to curate and discuss their personal choices is a really important part of what 主播大秀 Music does online. It harnesses the 主播大秀's role as a trusted guide and helps us build deeper relationships with our audiences on the 主播大秀 and in their digital social spaces. Radio 1's Big Weekend site and projects like feature elements intended to make discovery of those personal music choices even easier for our audiences. Radio 1's strength in social spaces means the conversation we can have about personal choices in music is ever more meaningful - keep your eye on and on Twitter and on on , on the weekend of 14th May.

We are also experimenting with location based services on site, building our own check-in service using . One of the motivating factors is to understand the safety and privacy issues around young people using check-in services but still allowing them the freedom to brag in a meaningful way to their friends that they are stood in front of . It also allows us to begin to understand how mobile will help us in the future, what an individual's proximity to others means, whether they are famous or simply a friend at any live event.
