These are supposedly pictures of the forthcoming Apple tablet user interface. Take these with a grain of salt, no doubt. It is likely that they were dreamt up by a fan.










What struck me about this design was how the keyboard was floated in a movable layer. I really like that idea. Because the tablet hardware would be a new form factor for many users, it may take a while for each person to find a comfortable position for the keyboard in terms of location on the screen/device, and in regards to the content being displayed on the screen. I assume a tablet could be rotated and held in many positions, so the optimal location for the keyboard could change in different situations.

For example, if the user is typing an email, they would prefer to have the keyboard front and center and taking up a large percentage of screen space. If someone is entering a search string, they may want the keyboard to be in a corner of the screen and smaller so they can focus on the search results. These scenarios also suggest that users may want to change the size of the keyboard depending on their mode. Of course, if the user is routinely changing the location and size of the keyboard, they will not be able to enter text very quickly.

I like the floating keyboard design because it makes this trade off from speed of keystrokes to customization and flexibility. This encourages exploration and experimentation within a new ui which could lead to entirely new and unexpected interactions.

I recently used a Wells Fargo ATM and I have to say it was the best ATM user experience I have ever encountered.

As with most people in the user experience business, I tend to be irritated by poor interfaces more than the average person. My observation of ATM's goes back a long time because they are some of the worst high usage consumer applications out there.

Features that top the list of ATM design annoyances include:

  • Using hardware based buttons for input on the side of the screen. Often the hard buttons do not align well with the screen option they represent. The user ends up bending over or stepping back because they are having difficulty targeting their chosen option.
  • Displaying static and active advertisements while the user is attempting to perform a task such as withdrawing money. This is a situation where marketing activity disrupts a user's primary task, withdrawing money, and interferes with a key benefit of using an ATM which is that it should be faster than going into the bank and using a teller.
  • Poor feedback that does not clearly indicate when a banking session is complete. This leads to people waiting in front of the ATM until they are positive their account cannot be accessed by the next customer.
The Wells Fargo ATM I used recently did a nice job in avoiding these problems and provided a clean and quick user experience.



The welcome screen provided clear feedback about the system state and instructed me on how to initiate a session.




After inserting your card, the task of entering your PIN was made very simple. The "OK" and "Clear" buttons were large, easily targeted by the user's finger, and color coded for emphasis.

I also appreciated the "Change Language" option being available but not intrusive.The color palette for this page was attractive and professional. The Wells Fargo stage coach branding across the bottom was clear and did not interfere with the user's task.




On this screen, the user selects an account to access. The targets were large and clear.



This page provided a simple, clean display of the account balance. The path forward was labeled "Continue," and was positioned in the middle of the screen and highlighted in green.




The primary tasks were displayed in the middle of the screen with shortcuts on the left.




Selecting a withdrawal amount. I liked that the amounts were displayed in the upper left corner of their respective buttons. As a result, the numbers were not obscured by the customer's finger.

I also received feedback about my selected account and transaction on the left.




On this sceen the user chooses whether to receive a receipt.




The system does a good job providing the user with feedback about the system state.




The system instructed the user to remove their card to receive their cash and the interaction ends.

The whole experience was expedient and error free. Kudos Wells Fargo Design Team.

On a related note, I happened to chat with a senior UE designer from Bank of America last nite. I suggested that there was little financial incentive for a bank to improve their ATM user experience. I do not think people are choosing a bank based on the user experience of the bank's ATM's. He pointed out that banks actually were incented to improve their ATM UE because a good ATM experience could reduce the number of customers that go inside the bank and require a teller's assistance.

Amazon.com recently released an electronic book reader, the "Kindle." The concept of the E-book has tempted consumer electronic makers for years. The benefits of the E-book are substantial: a limitless library of downloadable books, all the advantages of HTML including hyperlinks, bookmarks, version control, commentary options, etc.

The manufacturers' efforts have stumbled repeatedly as their products were unable to match the plain old book in price, visual clarity, weight, size, and ease of use. The interesting thing about the E-book failures are how they expose the overlooked strengths of paper books. In the case of the Kindle, this blogger notes his wife's disappointment in losing a sense of place from holding a book.

When we hold and read a book, we receive many types of feedback. The reader can tell how far into the book they are and essentially how much of the story remains. I assume the Kindle interface identifies current page number and pages left, however, I doubt these cues match the subconscious feeling one gets from holding a book and feeling that there are fewer pages left than those that have been read.

When confronted with anecdotes of new technologies not matching the older technologies they intend to replace, I sometimes wonder whether a younger user of the product would have different feelings on the matter. For example, my father and many from his generation strongly prefer to read their news in a newspaper rather than on the screen. I strongly prefer to read my news from the screen. I prefer speaking on the phone while younger friends prefer SMS'ing. Certainly preferences change based on past experiences and powerful new features may be unable to tempt people away from comfortable, old technologies.

I just came across a clever design for a toothbrush. The back of the brush can be used to redirect water like a water fountain so there is no need for a cup to rinse your mouth after brushing. It's a nice solution when a cup is not available. No more bending over to put your face under the tap or cupping your hand trying to get enough water.

It's been a fun day of watching the Superbowl. The technology applied to telecasting games over the last few years has really improved the viewing experience.

There is an overhead camera that gives the viewer a 3rd person video game style perspective. There is also the clever use of chroma colors to superimpose a yellow first down line on the field. Most football fans I have spoken with think of the chroma first down line as an indispensable feature after just a few years. It makes the game so much more dramatic as you see the players fighting to reach or defend the yellow line.

Another new Internet technology is the GameCast. This is an application that converts live game summaries to a visual display of the action. For example in baseball, a live representation of a diamond is shown. Instead of simply reading a game summary feed, a graphical display of the game action is presented on the GameCast diamond. It is not a very engrossing way to watch a baseball game, but it is better than a simple text feed. A key benefit is that it allows for viewer interaction, particularly with statistics. For example, the viewer may want to look up statistics about the pitcher for a specific situation. These types of stats can be quickly accessed through hyperlinks and predefined searches. This is a real asset for the devoted sports fan and it is a features that is not possible when watching sports on TV.

The next step in sports viewing technology is in the works. A cricket site called Cricinfo
is experimenting with broadcasting 3D animated versions of cricket matches. The description of the service is limited, but I am guessing it will be like a GameCast in that it will use game summaries to select pre-rendered 3D clips. For example, when the ball is bowled and hit to a specific fielder, the system will show a generic animation of that event. The precise spin of the ball, the running path of the fielder, the speed of the runners, etc. will not mirror the actual events - they will only be a high level representation of the real life play.

Using precanned animations will be a more engrossing experience than the GameCast and it also will take us one step closer to the next big thing: live 3D sports where the nuances and details of the game are presented to the viewer. While the development of a live 3D system is not trivial, the technology required to broadcast sports in 3D is already available. Were the players and ball equipped with wireless motion tracking devices and linked to 3D models like those seen in sports video games, the viewing experience could become very compelling and interactive. I can foresee a day when viewers could zoom in on the action or watch a play happen from a player's first person perspective. People could even watch from the ball's perspective. The ability to pause the action and access any statistic will bring fans even further into the game. This will be an exciting experience, indeed.
