Interview/Critique: The Beluga Razor and Website with Inventor Zac Wertz

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.

Interview: Using List Building to Start Your UX Freelancing Career with Jonathan Tilley

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:

and

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.

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.
