Motorola L6

Description following Norman´s Principals

Visibility: what to do and what to be done.
Mainly, what you can do is make and recive phone calls. The way doing it is simple if you know of mobile phones. Having a look at it you can see two main parts, the screen and the buttons, and you can also see how they interact. You´ve got functions writen in the bottom parto f the screen that corresponde to the top buttons, which is a way of getting started if you don´t know what to do. More specifily talking about the screen, at first sight you´ve got a few icons or words put on a background Picture. You´ve got the signal icono n the top left and the battery icon in the top right. It´s got the companies name in the midle “Orange” and the current date just benith it. In the bottom left there is the “Contact” Word and in the right side the “mesage” one. In the botom center there are a few horizontal lines that make the Main menú icon. The buttons set is composed by 22 buttons that are the main keys to control the telephone. Starting from the top, we see 3 buttons that have been explained before since they are the ones that do the functions that appear written in the screen. Just bellow them, you can see two other buttons, one on each side, and with a green and a red light that indicate the pick up or the hanging. Between these two buttons, there is a central panel with the form of a circle and 4 buttons that allow the main menu search and execution. The las 12 buttons are those that correspond to the numbers and the “*” and “#” symbols. The numbers are used for dialling and writing with the phone.

Feedback
The feedback is high because the screen reacts just by pressing a but, although it may not be easy to know what to do if you are not familiarized with phones, the information displayed makes the essential functions easy in a logical way. If some one picked up my phone and didn´t know how to use it, after looking at it, would probably press one of the numbered buttons since they are more in the centre and also bigger. After pressing the number, this one would appear on the screen, and the person would try to delete it so he would look at the screen and would see the word delete on it, so trying to touch it, he would accidentally press the button under the screen and then would understand how the buttons and the screen correspond. After doing that, the screen would go to the original page and then he would see the contacts buttons exactly in the same place where the delete was, he would press it and would see all the telephone numbers. If he wanted to select one all he would have to do is go up or down with one of the two arrows that are in the central panel and lighten up, choose the desired number and press the green button after that, which means “free to go”.

Constraints
There are many things that appear to be pretty obvious about the phone, like the size, that indicates its something meant to be caught and held in a hand. Buttons also gives you and idea so you press them, things happened, and then you can understand that you can use them with a specific purpose, and since that with an exception of very rare occasions, people know that it’s a phone, and probably find out how to use it fairly quick. So things like phoning or texting can be considered obvious because its what all phones do, but i.e. Bluetooth is something not so obvious. You wont get to know about it until you active the menu and you see the Bluetooth logo, and even so, you may still not know what it means. The word its self isn’t any clarifying neither, and even if you try to see what it is, you will have no chance of getting to know what it is for.

Mapping
The only mapping I see in the phone are the two buttons that correspond to the options writhen in the screen that change in function to the task you´re going to do. I suppose that when you activate the menu, the little panel you use to move around is quite mapping too, since its´ got the arrows that symbolise the directions you can move.

Consistency
If someone had to compare the phone to another one he had previously used, for example a Nokia, I think that he would find many similarities in the way in works and in how you can move your self around it. This is a great advantage when you just buy the phone because you don’t have to work out how it will work. That is something that use to happen before, and each mobile company did it their own way trying to gain people´s fidelity by making them not know how mobiles of different companies work, and making them seem very difficult to use. Fortunately, now days mobiles are all more or less the same, with a central panel to work the menu.
