• TOUCH INTERFACE: Consideration needs to be given to the type of gesture driven / tap type controls.
VoiceOver controls affect gestures used within player and web pages. There is a need to have a minimum of
onscreen buttons and the design aimed to follow accessible and ease of use design concepts [26]
• HTML5 VIDEO: Streaming video is easier on tablets than on mobile phones [27] and is the choice for
delivering a cross platform service although when fullscreen viewing with iPhones [28] the video is no
longer browser based and not presented within the webpage. This makes it impossible to add captions unless
embedded when video is made and external files will be unable to be read with the method presently used by
iPhones for rendering videos. The state of HTML5 and video is well explained by LongTail Video [29].
An Apple streaming video server [30] would now appear to allow for captioning on the iPhone whereas this is
not possible with YouTube videos. HTML video.org offer a helpful comparison of players [31].
