Insight
Interviews: Listen to what people say
Anthropological studies: Observe what people do
How do we find out how people behave in different situations?

Wearable Data Logging
Log data on Streamer, which many people have with their hearing aids

Wearable Data Logging
But people don’t use the Streamer!
Instead, use a device like a smartphone to log data (sound environment, location, time of day…) over a period of weeks
(Not so obvious in 2009!)

Obtaining User Input
Correlate collected data with hearing aid settings to find out what settings a user prefers under given conditions.
Present two settings, A and B User states preference Analogous to visiting the
optician.

Beta Test
3 hard of hearing Oticon employees Loved the A/B Test. 5 choices too many. Keep to 3 choices: A Better, B Better, No Difference. Using open domes, often could not tell difference. Use micro molds instead.
open domes micro molds (more closed fit)
