Hey all, there was an amazing event at Pixar last night and I was very lucky to be able to attend. Thought I would write up my experience for anyone interested.
I ended up winning two raffle tickets to the event offered by the Lighthouse for the Blind in San Francisco. The event was called "White Canes Red Carpet" and was held at the main Pixar campus in Emeryville, CA. Several blind groups were in attendance, including the Lighthouse, CCB,Blind Babies, OCB, Lyons, and the CSFB. Prior to the event, we were instructed to download a beta application on our iDevices. Unfortunately, the install credentials were wrong and the Disney app team had to help everyone install it at the door.
They actually laid out a 150' red carpet down the center of the Pixar atrium flanked by statues of characters from The Good Dinosaur, which was what we were there to experience. My girlfriend and I were a bit rushed in checking out everything offered to the crowd due to some transportation issues and arriving late along with the bottleneck of attendees who needed the app installed, and eventually they funnelled us all to the theatre.

The app worked like a charm. The Good Dinosaur description was alreadt offered within the app,. Worked seamlessly with VoiceOver, and the information page for the movie had an audio description sync button that would auto-sync to the movie by listening to the sound in the theatre via an active mic. We had the option of listening to description only, or have description mixed with the actual movie audio through our earbuds/headsets. The description only mode was much better, IMO. This basically allows you to control your own descriptive experience in theatres rather than relying on shoddy audio description units and incompetent projectionists/managers.
Unfortunately, my battery drained almost 50% through the course of the movie on my iPhone 5S, but I gladly would prefer having to recharge my battery or carry a charge pack rather than having my sighted girlfriend have to miss out on the openings of movies when the stupid descriptive unit fails to work. The app had The Good Dinosaur preloaded for us, but was also populated with almost all of the Disney classic animations, other Pixar films, and Marvel and Star Wars properties. Conceivably, you would be able to sync up description at home when watching with others, and not have to worry about people with vision getting distracted or missing out on sound effects/music with the audio description on. Plus, this means that older movies released before audio description was available will now be able to get their own description tracks, opening up the world of Disney and Pixar animations to those of you were unfortunately not able to physically see them.
Have not been able to test this functionality with any other movies so far, but I am greatly looking forward to it in the future!
