Zac Wertz, inventor of the Beluga Razor, joins Tim Keirnan for an interview about the design of both the Beluga Razor prototype and the BelugaShave.com website. Across 80 minutes of uninterrupted, commercial-free conversation, Zac and Tim discuss hardware and digital designs, including
* Their mutual dissatisfaction with modern cartridge razor shave quality, its high cost, and environmental problems
* Their appreciation for traditional safety razor shaving
* Zac's origin story for inventing the Beluga razor
* How Zac designs mechanical prototypes
* The design of the BelugaShave.com website to reinforce the Beluga brand
* Tim's experience shaving with the prototype
The Beluga razor combines the advantage of the modern cartridge razor--a pivoting head--with the advantage of the traditional safety razor--its single, double-edged razor blade. Users thus have the low cost, superior effectiveness, and environmental advantages of traditional safety razor shaves without having to learn the fine motor skills needed for using a traditional safety razor.
P.S. You can listen to older shaving-themed episodes:

Jonathan Tilley, voiceover professional, joins Tim Keirnan for a discussion on how user experience professionals can find freelancing opportunities, either full or part time.
This episode is about designing one's career instead of designing a digital or hardware experience, and closes with a discussion of how college students could use list building to find an internship or first job.
Jonathan's websites are:
Audiophiles take note: As a professional voiceover artist, Jonathan already sounds good. His choice of the Neumann TLM 103 microphone is why his good voice sounds so amazing in this Skype recording with Tim. There is no additional processing on Jonathan's voice. What you hear is his voice through the proximity effect of a magnificent and expensive-but-worth-it cardiod mic.

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 strenghts 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...

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.

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
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!

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.

A heartwarming holiday tale of good customer service after the sale. Nokia politely and efficiently repaired Tim's Lumia 710 Windows Phone, using a combination of good website design, excellent customer service desk people, and a "do it right the first time" service department.
Companies that care about their customers will save the brand's relationship with the customer when something goes awry. In particular, Nokia did three things to keep Tim's loyalty to the brand when disaster struck:
1. Effective and consistent communication, both on their website and in person via telephone.
2. Action that matches words with deeds. No hypocrisy or lies.
3. High speed of resolving the problem--efficient solutions done right the first time.
Thanks to their professional handling of the problem, Nokia has not lost a customer. Obviously this is something that T-Mobile doesn't care about, as evidenced by our previous episode, but to Nokia's credit they "get it".

Even when the initial user experience of a product is good, the total customer experience suffers when a company ignores service after the sale. We at Design Critique argue that service after the sale IS AN INTEGRAL PART OF A PRODUCT'S DESIGN because it directly affects the customer experience. Only bad companies isolate product design from customer service design. In Tim's case, T-Mobile destroyed a loyal, 8-year customer relationship for its monthly prepaid service by
* Refusing to help replace a smart phone under warranty when it broke, in any kind of realistic time frame,
* Refusing to unlock the phone after selling it on the condition it would be unlocked after 90 days, and
* Implying its monthly prepaid customers are not worth helping because only long term contract customers deserve good customer service.
It's a comedy of errors unless you're the one who wasted hundreds of dollars and hours of time dealing with T-Mobile's agressively anti-customer practices. What lessons can we draw from T-Mobile's mistakes?
One anecdote does not make a statistically significant trend, but anecdotes provide useful insights into the how and why of customer service failures.

Tobby Smith returns to help Tim provide a longitudinal review of Nokia's Lumia 710 Windows phone. After over eight months of use, the Lumia 710 proved itself a terrific value in smart phone quality, including
* Convenient, portable size with grippy back cover that can be switched with other colors to personalize the phone
* Hardware buttons for the three standard Windows Phone buttons, instead of the soft buttons so often found on other models. We find dedicated hardware buttons much more usable.
* Clear and bright screen with high contrast.
* Good video recording.
* Superior applications specific to Nokia phones, such as Nokia Drive.
* Tim's phone broke after only five months without any abuse or dropping.
* Still camera images are average at best.
* Volume of speaker is not loud enough to hear nav instructions above road noise or stereo playing.
Despite the dislikes, the Lumia 710 is a great value-priced smart phone. As Windows 8 phones roll out, it may become even cheaper to buy and thus an even better value for customers who don't need the advanced functionality of Windows Phone 8.

The GoldStar MA6511W microwave oven is a triumph of kitchen appliance interaction design. Featuring only two mechanical controls that are all too rare in an age of overly-complex digital designs, the MA6511W deserves as much praise as can be put into this 16 minute episode. The adjective "intuitive" is often over-used, but it applies to this small microwave oven.
Microwaves are functionally simple devices often made difficult to use by manufacturers who put frivolous features and buttons on something that doesn't need to be complex. A mad dash for "features" at the expense of audience needs and usability is common in microwave oven design, but GoldStar's design team tightly focused this oven for a particular audience (re-heating in space-cramped kitchens) and did NOT try to please everyone. The result is a wonderful appliance that has also proven very durable--7 years of trouble-free service at the time of this episode's publishing.
