iPod Touch: Music Player or Phone-without-a-phone?

Image de Jay Vidyarthi Jay Vidyarthi - Comments 7 Commentaires

I was completely blown away when I first played around with an iPhone. However, with no desire to subscribe to a 3-year contract, I was relieved to hear that the iPod touch provided the same interface and similar functionality without any monthly services; an iPhone-without-the-phone, so to speak.

While the iPod Touch allows me to connect to my home wi-fi network and play with its supreme functionality, I can’t escape the feeling that Apple forgot to ensure a music listening experience which meets the same high standards. As a company focused on innovative user interfaces, anyone at Apple should have cringed when they read that.

Both of the problems detected involve a failure to capture a music lover’s flow of needs. Here, I would define music lover as anyone who is very particular about music, with urges to hear specific songs and an inability to sit through any song they are not in the mood for. The iPod touch runs into problems with the music lover’s experience when it is resting in the user’s pocket with a music library playing at random. I have identified two specific problems here:

1.  Since I have 6 gigabytes of music randomly thrown into my ears as I walk the streets, it’s inevitable that a song which is inappropriate for the current moment will come on.

With my iPod Touch, I am forced to pull out the device, push a button to activate the screen display, swipe my finger on a slider displayed on the screen to remove the ‘hold’ feature, and finally push the ‘next song’ indicator displayed on the screen. This is not only a more complex user interaction involving both haptic and visual interaction, but pulling out the device itself is also very frustrating when you’re forced to take off your gloves and unbutton your jacket because you’re outside in Montreal when its -30C. Maybe it’s time for Steve Jobs to visit a cold climate!  This problem can only be solved with an external remote which must be purchased separately.

Contrast this to my iPod Shuffle, where i could feel the surface of the player through the fabric of my pocket, hold down the play button to remove the ‘hold’ feature, feel the simple circular button interface and skip the song. I didn’t have to take the iPod out, put my hand in my pocket, or buy an external remote to get the job done. Oh, and did I forget to mention that it was only $40 when I bought it used from the owner of a Depanneur on Sherbrooke St?

2.  I also noticed a second problem when listening to music at random with the iPod Touch in my pocket.  When a song comes on, often I will be inspired to listen to a different, related song. For instance, my randomized playlist might give me “Shoo Shoo Boogie Boo” by Big Joe Turner. I might decide that I’d rather hear “Shake, Rattle and Roll” by Big Joe.

On the iPod Touch interface, there are convenient features which allow me to browse songs from the same album/artist; however, when I select one of these songs, it is impossible to instruct the device to resume my random playlist when the song finishes. I am forced to wait until the song is over to perform this function, forcing me to either hold on to my iPod until the song finishes, or take it out of my pocket again 5 minutes later.

With my Shuffle, the song-selection interaction is obviously limited by the lack of a screen.  Even still, there are aspects to the interaction which are easier.  The Shuffle controls randomization with a physical switch.  I reach in my pocket, turn random play off, switch between songs in the current album, turn random back on.  After playing my desired song, the player will continue its random playlist.

Why are these minor problems a big deal when, obviously, the benefits of the Touch compared to the Shuffle are tantamount?  Here’s where the problem ties into User Experience!  I can’t shake the undeniable feeling that Apple simply released the iPod Touch to cash in on the buzz surrounding the iPhone, without seriously considering its role as a music player, not a phone.  I also can’t shake the fact that I was a victim of this marketing ploy, which severely decreases my trust in Apple products.  That’s a big deal.

For anyone who doesn’t know Big Joe:  Big Joe Turner - Shake Rattle and Roll

There’s not really much to say about this one.

I highlighted a particularly salient aspect of the usability crime, but I think it’s pretty obvious how this could be confusing to users.

Guidance : Readability and graphic treatment of labels

Image de Benoît Decomble Benoît Decomble - Comments Ajouter un commentaire

Self-proclaimed as the new “Youtube Killer”, Hulu, the project of both NBC and News Corp, just came out as a public beta.

The launching was a great success; unfortunately, we can’t access all the great content outside the U.S.

The site is visually appealing and very interesting (even if it’s similar to Apple’s graphic style). The graphic grid is clear, the content is easy to read, everything flows… However, a navigation problem caught my attention in the very first minutes. It looks like an insignificant detail at first, but it quickly gets really frustrating!

The problem is the following: we don’t notice that “TV” and “Movies” at the bottom of the screen are buttons right away.

Each section menu is presented as in the picture below:

Continuing in the series of “design mistakes”, here is a screen shot of a very simple interface where there is a only one button. However, despite its simplicity we can find a major mistake.

The most important actions on an e-commerce web site are:

3 Online Shopping Sites = 3 Difficult Experiences

Image de Joëlle Stemp Joëlle Stemp - Comments Ajouter un commentaire

There’s nothing like a real-life experience to evaluate a transactional Website. Here’s a realistic experience: we were looking for several high-tech products and wanted to buy them online.

The Objectives:
- To save some time by shopping on the Internet
- To get the best price for the highest quality product, of course…

The Products:
- Two laptops with two-year extended warranties and Windows XP as the operating system (no, not Vista)
- Three 19-inch LCD monitors
- One digital camera with integrated hard drive

The Websites Used for Purchase:
- Futureshop.ca
- Bestbuy.ca
- Staples.ca (Business Depot)

The Website Chosen to Verify the Products’ Reliability:
- Cnet.com

The Technology Environment
- Laptop PC
- Browser: Firefox 1.5.0.8.
- High-speed Internet
- One credit card…it was even valid!

User’s Profile?
- Internet expert

What were the results of all of these transactions?

- Two successful online transactions (Best Buy and Staples); two trips to the store (to Futureshop to finally buy the product in person and to Staples to add the extended warranty); the feeling that I had lost my own precious time.
- Being able to compare the products to one another and to the competitors’ prices was a positive experience and represented a significant savings in time. The consumer is more informed and feels a greater degree of control over the process.
- The complete process took between 4 hours (for the laptop computer) and 6 days (for the digital camera).
- Increasing frustration over the fact that online shopping sites don’t seem able to effectively manage the online shopping process, nor the payment option, and that it is so difficult to find an agent to speak with.

How could these three sites improve the user’s experience?

- Connect the user’s needs with the site’s functionalities and quickly identify information essential to an online purchase by employing User-Centered Design (UCD), including simple techniques like Task Analysis and Usage Scenarios.

- Usability Testing with real users placed in real, life-like situations would have helped identify usability obstacles.

- More effective customer service, including an easily-available phone number, would help clients validate uncertainties more quickly.

If these three sites were to optimize their online purchasing processes, their clients would be more satisfied, their online sales would increase and they would achieve a greater return on their investment.

What organization could say no to that?

An error message without error?

Image de Marcio Leibovitch Marcio Leibovitch - Comments Ajouter un commentaire

Still about error management and recovery, last week I was working with Macromedia Dreamweaver when for no reason this message was displayed:


An error message that says there’s no error!

A funny message for those who know this is a bug but an example not to follow for those who want to help their users recover from their own mistakes.
