Critique: Magellan RoadMate 2230T-LM GPS

Brad Jensen returns to help Tim critique the Magellan RoadMate 2230T-LM portable GPS. This completes our series on portable GPS for the car and provides a fascinating look at how three manufacturers have designed similar solutions. The strengths of the Magellan include
* Text entry is spoken by the unit to confirm input
* Dynamic rerouting around traffic problems works well
* Effective use of corners for touch points
* 4.3 inch size is not ungainly as the 5 inch Garmin was

Usability problems with the RoadMate could be summed up as bad color choices in the UI. The garish display and the difficult to read road names, plus general clutter that is unnecessary to help the user, are unfortunate negatives.The update software is also poorly designed and confusing to use.

Melissa Smith joins us for another Human Factors News Desk segment. Citations to follow as soon as I find them…

WordCast: Verbal Protocols (Thinking Aloud)

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.

Critique: Android Phones Longitudinal Reviews of LG Motion and Google Nexus 4

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).

LG Motion:
* 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

Nexus 4:
* 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.

WordCast: User Experience 101

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.

8th Anniversary Show with Tom Brinck! Step Stool Critique

On the 8th anniversary and 100th episode of Design Critique, Timothy Keirnan is joined by a celebratory guest who is no stranger to long-time listeners of the show. Our topic is the design of an everyday object that helps everyone reach a little higher in life: the step stool. We like how such a simple object has so many facets, features, and personas for design consideration.

We’d like to thank everyone for listening the past eight years and helping us reach the milestone of episode 100. If you appreciate Design Critique, please write a review of the show on the iTunes music store. We need more reviews and it only takes a couple minutes.

The first step stool we discuss is designed towards children and a product description is at

The second step stool we discuss is suitable for adults who need one that folds up when not in use and can be seen at
http://www.amazon.com/gp/product/B00004SAC3/ref=oh_details_o02_s00_i00?ie=UTF8&psc=1

This episode closes with some old outtakes from the early recordings we did at Country Squire Studio 1 from 2005-6. Ahh, memories. Thanks for listening!

Critique: Garmin Nuvi 50 GPS Longitudinal Review

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.

http://designcritique.net/dc86-longitudinal-review-tom-tom-xl335tm-portable-gps

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.
