Usability Journal Post #6

The front facing camera of a smartphone such as an iPhone is an example of good usability. Instead of having to turn the screen away or using a mirror to take a selfie, the user can keep the screen facing him/her while taking that selfie. This gives the user feedback as to what the picture will look like, since the image being captured by the front facing camera is being displayed on the screen. This system affords the user the ability to take a picture of them self or with others, or use a video calling feature such as FaceTime. The only possible improvement to this system would be to include higher resolution front facing cameras in future smartphones. Current cameras can be a bit blurry, especially in low light, but this is more of a functionality problem than a usability problem.
