MoDevUX was located in Canvas' backyard this year so I couldn't help but attend and see what I could learn from my peers. The convention held a wide arrangement of speakers, workshops, and attendees from a myriad of industries focused on improving their mobile experiences.
In the workshops and lectures there was a great deal of discussion on UX silver bullets and best practices for apps. Do you always go native option? HTML5 maybe? It was a mix and match solution in my opinion, but that probably depends on who you spoke or listened to. There were also a lot of conversations on metrics and methods to gather and track responses such as tobii's mobile eye tracking solutions.
As a UI/UX professional with a heavy creative background I feel I had a different experience from the dev heavy crowd, even though charts stated that 40% of all content was design focused, but I learned a good bit myself. I mostly attended multiple smaller workshops before the full conference to pick up as much variety as I could.
The following are a few of the presentations I enjoyed, (my focus being mainly on things I could pick up to refine GoCanvas of course) so they may not be interesting to all parties. Anyway, take a look at some presentation decks from MoDevUX 2013.
