Early Stages Design of Mobile Applications

Lessons from Early Stages Design of Mobile Applications [1]


This paper is about the design process of a mobile application that require human interaction and the stages that this process goes through.


1) One of the strengths this paper had was explaining the process of creating an interactive system that is very complex from the starting phases of it. More specifically, "(1) data gathering; (2) prototyping; and (3) evaluation"

2) Another thing which I had never thought of when creating a device is to create a prototype that does not even work, I thought it was really interesting that they created a device out of some wood and paper and let the user act like they were using it to study how it will be used before even creating it.

3) Even though it did not talk about every specific topic in the variables that would affect the use of the device, I think they did a good job at covering a broad view of them.


1) They did say that they give questionnaires to the people after they have used the product to evaluate it, but it did not really say anything about just observing the users to see how they are using it, which I think is just as important because in the product evaluation they can put what they want, and entrusting that they are honest. While observing them will give the developers feedback from their perception.

2) I noticed when they were talking about the different types of scenario variables that they were not covering all of the possibilities for them. For example with the Movement and Posture; there are many more things a person can do then just those three.

3) They said that when a user is in a different position, that the device might have to change the font or icon size depending on the distance between the user and the device. I do not think that this is a good idea, because then it seems like the sizes will always be changing since a device is never consistently at a fixed distance away.
