Abstract
  • As of February 2012, approximately 46% of American adults own a smartphone. The graphics quality of these devices gets better each year. However, they still have many more limitations in graphics processing and storage space than desktop computers. This means that applications on these devices should focus on optimizing their file sizes and graphics quality in order to maximize the number of devices that can run and store them. Unfortunately, there is no defined metric for graphics resolution on smartphones. This thesis explores what users believe to be the minimum acceptable graphics quality in smartphone games and graphics applications. By using a testing program we designed in OpenGL, we were able to find at what point in an image’s degradation users found it graphically unappealing and found the app unacceptable. Participants gauged four images that degraded over time. For our two high frequency images, participants found the minimum acceptable graphics quality to occur at 43 pixels per inch (ppi), while in low frequency images they found minimum acceptable graphics quality to occur at around 31 ppi, with the average minimum being 37 ppi.
