Being a graphic design teacher and the yearbook advisor, I take full advantage of the digital technologies I have at my school. I use on a daily basis my digital camera to capture photographs for project use as well as pictures for placement in our annual yearbook. I must be able at times to call upon my students to capture quality photographs and download them onto our computers so the photographs can be edited. This
usability test will provide feedback for me as well as the manufacturer
on how
user-friendly this product can be. The
test will determine if a first time user of the Nikon Cool Pix 4300
Digital
Camera can turn it on, adjust the image quality, adjust the image size,
take
two photographs, download the photographs onto a computer, and call up
their
photographs. |

Five participants
were selected from three high school
technology education classes. The
participants were brought individually into the test administrator’s
computer
lab for an overview of the usability test and then the test
administrator distributed
a brief pretest. Upon the completion of
the pretest, the participants began following a verbal script of five
tasks to
complete. The administrator observed each
participant as they completed the five tasks. As
the administrator observed, he also recorded comments
for each
participant at the completion of each of the five tasks.
After each participant completed the five
tasks, they were given a survey to complete. Each
student then had an in-depth debriefing to clarify
any problems
they might have had with any of the five completed tasks.
The administrator expressed his gratitude to
each participant and then signed a pass for them to go back to
class.

| Based on the observations, comments, and feedback from the
posttest, the participants found the Nikon Cool Pix 4300 Digital Camera
fairly easy to use. The participants who expressed a high level
of ability and experience with a digital camera used the camera with
great ease. Those who expressed low or no ability with a digital
camera were able to complete the tasks with little trouble and
frustration. All participants were able to complete all five
tasks. Task 2 (taking a photograph of a football) was easy for most of the participants. One of the five participants had trouble finding the auto mode to photograph the football Task 3 (zooming in and taking another photograph of the football) was the easiest task for all five participants. Task 4 (placing the memory card in the card reader and downloading the photographs onto the computer) seemed to be the next difficult task for the participants to complete. All five participants placed the memory card incorrectly into the card reader. On the second try, all five participants completed the task in the correct manner. Task 5 (calling up both photographs) was very easy for all participants. Back to the Top |

As a direct result of the
observations, comments, and the posttest made throughout the usability
test, the following conclusions and recommendations can be made:
The Nikon Cool Pix 4300 Digital Camera
received a much lower than anticipated user-friendliness mark when it
came to adjusting the image quality and image size in the set-up
menu. A recommendation could be that when the camera is
turned on that the set-up menu automatically displays on the
screen. This will increase the user-friendliness of adjusting the
image quality and image size.
Another low mark came when the memory card had to be placed into the memory card reader. A recommendation for this could be that when the memory card is ejected from the camera, it would have an arrow and text describing the correct insertion of the card into the reader. The anticipated low user-friendliness mark was actually a very high user-friendliness mark when it came to the camera interface with the computer. All five participants excelled when it came to downloading and calling up the photographs onto the computer. Most of the participants remarked that after using this particular digital camera for the first time, that they could easily get accustomed to this camera. They were impressed with the quality of photographs that could be taken and the short amount of time it toook to get from the camera to the computer. Back to the Top |
