Dr. Robert Youmans from George Mason University joins Tim Keirnan for a wordcast episode on verbal protocols. Why and how do we ask usability research participants to think aloud about their task performance, and what does using this method do to our data? Dr. Youmans covers four different methods of thinking aloud:
1. Concurrent Verbal Protocol
2. Retrospective Verbal Protocol
3. Interruptive Verbal Protocol
4. Prospective Verbal Protocol
The remainder of the episode covers research on how using concurrent verbal protocol can affect your data. People do not normally think aloud while doing tasks with products, and having them vocalize during user research can change their behavior, but the degree of change may not be a problem for the goals of our studies. Sometimes thinking aloud can improve their performance–which also affects your data. The result is not obvious and the literature is conflicted.
Mike Velasco joins Tim Keirnan for an episode to discuss the customer experience of two Android smart phones: the LG Motion and the Google Nexus 4 (also manufactured by LG). These two very different Android phones each have their own advantages, as do the carriers Tim used them on (MetroPCS and Solavei, respectively).
* Small size easy to hold and put in pocket
* Fast data speeds
* Replaceable battery
* Custom Android user interface by LG that isn’t bad
* Outright purchase from MetroPCS on a monthly, non-contract plan
* Large screen easy to read for older eyes and for gamers
* Pentaband GSM radio frequencies ensures it works anywhere in the world
* Pure Android operating system with the UX that Google intended, gets updates instantly from Google as they appear
* Outright purchase from Google at very fair price, can be used on any GSM carrier including monthly, non-contract plans
Listen to the episode for other facets of the customer experience of owning these phones.
Dave Mitropoulos-Rundus returns for a wordcast episode on the user experience profession that probes the origins of our field. Where did it come from, and how did we come to have jobs in it? And is “customer experience” a better phrase for what we do?
For us, UX is about managing risk on projects by doing our trio of research, design, and testing to ensure products and services will meet business goals. And it’s about taking pride in one’s craft.

The first in a series of Bad Button Labels We Have Known. Brad Jensen joins Tim Keirnan to discuss the Chaos button on his father’s new microwave oven. Why do companies allow such dreadful UI labels? Mr. Jensen’s microwave is the first of many terrible examples we plan to cover on occasion in future episodes.

Brad Jensen and Tim Keirnan present a longitudinal review of the Garmin Nuvi 50 portable GPS. What does it do well, and how could its interaction design and interface design be improved?
An earlier episode of Design Critique reviewed a TomTom portable GPS and you might want to go back and hear that along with this episode.
Both TomTom and Garmin solve the navigation problem for their customers in ways that are both familiar and different. Neither unit provides a perfect solution, but it’s fun to talk about.
