Audio Geotagging

This project involves developing a tablet application for audio geotagging. The student will work towards building a system to capture time-stamped audio and touchscreen map interactions. Ideally, the student would produce a prototype application that records where and when users touch a map display during an interview, and automatically relate the locational data to the time in the interview when the gesture was made. Following a recording, it should be possible to search within and across interviews using geographic queries (e.g. "show me all interviews that mention "Lake Taupo" or "take me to the point in this interview when the interviewee referred to Mairangi Bay"). It would be desirable for the project to include a small set of pilot interview usability tests.

Although this project is focused on geographic maps, it may be extended to any visual display (e.g. collections of photographs, diagrams). Audio created using this tool (both English and Maori) would ensure that rich geographic metadata is automatically generated for the digital item. This streamline an important aspect of cataloguing/description and ensures that place and time are point of entry for search -- two key organising principles for the retrieval and citation of information. These audio and /or video recordings could be oral history recordings, for family/community/etc local and public history projects, public lectures and teaching sessions. The tool also has public good applicability beyond the library and information professions, being invaluable for health professionals working with Alzheimer patients, trauma victims, etc. Scientists and geographers would also be able to use the tool for mobile data capture in their fieldwork.
