The goal of this capstone project is investigating a dual screen device through the perspectives of both physical and user interface. Dual-screen devices from Dell have not been released on the market, and this provides great potential for usability research. Currently, there is very little user experience research that has been done on dual-screen devices. For this reason, this study anticipates user contexts and tasks to develop usability insights. Therefore, the experiment includes four common tasks derived from smartphone interaction and usage from previous single screen device research. These include writing a text message, reading a text, taking a photo, and watching a video. The method analyzes user posture and level of thermal conduction depending on materials used in dual-screen devices. The results include four distinct heatmaps showing areas of touch. Based on this research, final recommendations are given on dual screen thermal durability.
