American Sign Language and Audio Description on the Mobile Guide at the Museum of Fine Arts, BostonThe Museum of Fine Arts, Boston, celebrating the opening of its new Art of the Americas Wing in the fall of 2010, replaced its fleet of audio guides with iPod Touch-based mobile guides. In addition to this new delivery platform, the MFA began producing all of its mobile tour content internally instead of relying on an outside vendor. The new MFA Guide, as it was dubbed, provides the opportunity for broad accessibility of content—options include audio description, American Sign Language, and text transcript—as well as the flexibility that comes with producing the content in-house. And because the player is an iPod Touch, it comes with the accessibility options of Apple products, among them a screen-reader and zoom capability. One of the goals of the MFA Guide was to harness technology to deliver content to the full range of viewers, from families to users of different languages to people with disabilities—all of them on the same guide, rather than, for example, having a separate device for a descriptive audio tour. Here I focus on two aspects of the Museum of Fine Arts, Boston's new approach to the mobile guide: the addition of American Sign Language (ASL), and the expansion of audio description. The American Sign Language tour became the eighth non-English language in which the Collections Highlights tour is offered. (The other languages are Spanish, French, Chinese, Japanese, Italian, German, and Russian.) Over 100 stops—which are focused on treasures throughout the museum—are currently offered in ASL. Whenever a new stop is added to this tour, it is translated into the aforementioned languages, a narrator records the script, and a guide who is Deaf signs for the ASL portion
