Positive UX: Optimal user experience is more than the absence of usability issues

The study of well-being focuses on the topics of positive psychological functioning and experience. It has captured the interest of moral philosophers for centuries. In this article I draw parallels between the fields of well-being and UX in order to illustrate the factors that define and foster ‘Positive UX’ and the implications this may have on measuring good experience with the web.

Detecting browser compatibility for HTML5 video and audio

Different browsers offer different levels of support for HTML5 audio and video. Where some browsers support one type of media file other browsers will fail to do so.
