Immersive Sensory ExperiencesSightSoundTouchSmellTaste

Multimedia will become a fully immersive experience that takes over all of our senses

Ethical ConsiderationsWill it come with an off button?Will we have adverts pumped directly into our

heads?Will everything we do be monitored and tracked?Might we get hacked? These are important questions that don’t just

relate to the above future scenario they are questions that we need to think about in the here and now.

So what is Multimedia?Depends who you are…

PC Vendor PC with sound & video

Potential ApplicationsVideo conferencing – SkypeDistance learning – Open UniversityCooperative applications – Google docs / on-

line gamesAugmented reality – Google glass (Last

sighted in a local CEX store) – Oculus rift

Hypermedia Not just text based

Electronic newspapers Reference tools Games Home shopping On-line study Video / Film on demand

A user interface should be so simple that a

beginner in an emergency can understand it

within ten seconds. Ted

Nelson.

The World Wide WebUp until about 1989 the Internet existed

quite happily without the World Wide Web

File Transfer Protocol (FTP) TelnetUsenet

World Wide Web is not the Internet!

Hyper Text Transfer Protocol (HTTP)A protocol is an agreed set of rules for doing

somethingHTTP designed for transmitting hypermediaThe Uniform Resource Locator identifies the

resource accessed

For example the URL: http://www.cse.dmu.ac.uk/~mjdean/

time.shtml

Some Processes in HTTP

Client side scripting

Problems and Limitations Associated with HTMLThere are two issues associated with HTML which need to

be considered Standardisation (or lack of) "Browser Wars"

HTML is a mark-up language and is not very good at specifying presentation Introduction of Cascading Style Sheets

The World Wide Web Consortium  http://www.w3.org"W3C primarily pursues its mission through the creation

of Web standards and guidelines"

HTMLMuch tighter specification devised based on XML i.e.

XHTMLXHTML - transitionalXHTML strict

Unfortunately the standards were not widely adoptedSome people went back to HTML 4Some stopped at XHTML transitionalSome browsers didn’t implement the support for XHTML

 2006 the W3C changed their mind and around 2007 pretty much abandoned XHTML in favor of HTML 5

Follows many rules of XML but more relaxedIncludes native support for multimedia
