HF: Media Device Usability Research

This is the final poster that I created to visually display my research and the findings. Details of the process and findings can be found in the next series of images.

Me and my final poster on presentation day.

My Sketches of the Physical set up of the study with Setting A (Laptop&Projector) and Setting B (iPad & iPhone on a stand)

The actual set up of Setting A. Laptop and mini projector linked screens so that both participants could see the screen. Two people participated at the same time in a collaborative task. Each person stood across from each other at the standing workstation developed by the grad student collaborator.

The actual set up of Setting B, iPad and iPhone on movable stands. This was the test setting to see whether it actually allowed for more workspace, was more efficient, and promoted more collaboration.

Procedure included participants setting up devices, researching activity designs, building a lego catapult with physical materials, taking a picture of their masterpiece and uploading it to a website, and lastly cleaning up. The three tasks displayed in the graph are the tasks that the experimenter (me) timed to test the efficiency of the interaction with the devices. Setting A (Laptop & Projector) took significantly longer to set up, upload a picture, and dismantle.

A paired samples t-test across settings was done to see whether these timed results are statistically significant. All three tasks that were timed came to be statistically significant that Setting B was more efficient.

A usability questionnaire was given to collect overall user experience data and participant anecdotes.

An example of a user scale for Setting A, same questions were given to rate Setting B as well.

Here is what the results were for the first set of questions relating Setting experience. Generally, Setting B was much easier and less frustrating to use. Important to note that participants felt that Setting B was more appropriate for this particular workstation.

Results for second set of questions in which Setting B proved to be more collaborative. Important to note that Setting A was far more difficult to upload a picture.

Comparisons of Settings

Results for the third set of questions comparing both settings. Surprises in the data include that the level of collaboration was about the same for both Settings.

Questions asked about overall experience in text. Sample of quotes as displayed on the poster.

Description

This study is an exploratory study of the influence of media devices on a standing workstation. The comparison is of the affordances of media devices with different form factors. A Recommendation for the best configuration of media devices that afford collaboration will be made for the Makerspace at the Tufts Center for Engineering Education Outreach.
