On 18th March we held a 1 day competition on Twitter (@marekpawlowski and #mex09), challenging industry pioneers to come up with the best definition of ‘mobile user experience’. The prize was a delegate pass, valued at GBP 1499, for the 5th annual MEX Mobile User Experience conference on 19th – 20th May. The event sells out in advance every year with a long waiting list, so it was a great opportunity for an individual developer or small company to get their hands on a ticket and join the industry’s most creative thinkers at MEX.

Here are the entries we received:

@haysom_runner: fast, simple, relevant, necessary and safe!

@Klaasdahaas: The combination of user actions noticed, and noticed quality of goal accomplishment defines the Mobile User Experience

@barbaraballard: Mobile user experience: How people interact with a brand using the data devices in their pockets

@millarm: design to keep cost low and meet legacy revenue and marketing buzzwords of operators – people an afterthought

@mattdavies: Mobile user experience: Encompasses every interaction and emotion a person has with their mobile device in their daily lives.

@synaesthete: Mobile User Experience=the practice of designing handheld devices to help people get connected with each other, entertained &informed

@Klaasdahaas: Mobile user experience is the extent of freedom a user feels to connect to the world

@Klaasdahaas: Mobile user experience = the sum of the emotions felt during the interaction plus the change in mood caused by the interaction.

After careful consideration, we decided @mattdavies was the most complete definition of mobile user experience:

“Mobile user experience: Encompasses every interaction and emotion a person has with their mobile device in their daily lives.”

Congratulations Matt, we’ll look forward to seeing you at MEX on 19th – 20th May in London.

Thanks to everyone who took part and re-tweeted the competition.

We don’t have any more free passes to give away (MEX attendance is limited to 100 mobile user experience pioneers and sells out every year – buy one here), but please feel free to send in any additional ideas for the definition of mobile user experience if you want to join in the discussion.
