Recently usage of multiple devices including mobile devices, TVs, OTTs, game consoles, have been extremely increased, allowing multi tasks to users. In addition, the rapid increase of connectivity between the devices has occurred. However, the issues of limited connectivity, battery (power) consumption rates, different remote controls and limited input modalities give rise to uncomfortable experience for users. The more usage of devices increase, the better users require usability. The present study describes which factors and attributes are most relevant to improve usability. We place emphasis on designing methodologies of pilot study to enhance usability thorough data collection and analysis. As a result, we define usability model of multiple devices by those factors and attributes.
