ISO Standards and user centered design

All these approaches follow the ISO standard Human-centred design for interactive systems (ISO 9241-210, 2010).

The ISO standard describes 6 key principles that will ensure a design is user centred:

  1. The design is based upon an explicit understanding of users, tasks and environments.
  2. Users are involved throughout design and development.
  3. The design is driven and refined by user-centred evaluation.
  4. The process is iterative.
  5. The design addresses the whole user experience.
  6. The design team includes multidisciplinary skills and perspectives.

“What happens when people are learning and using a system is that they develop knowledge of how to use the system, and, to a lesser extent how the system works. These two kinds of knowledge are often referred to as user’s mental model. (…) The more someone learns about a system and how it functions, the more their mental model develops. (…) Within cognitive psychology, mental modelshave been postulated as internal constructions of some aspect of the external world that are manipulated enabling predictions and inferences to be made. (Craik, 1943). This process is thought to involve the “fleshing out” and the “running” of a mental model (Johnson-Laird, 1983). This can involve both unconscious and conscious mental processes, where images and analogies are activated.” (pp92-93)

Interaction Design: Beyond Human Computer Interaction by Jennifer Preece

Cognition has been described in SIX KINDS OF PROCESSES:

  1. Attention – selecting things to concentrate on
  2. Perception / Recognition – how information is acquired from the environment via sense organs and translated into experiences (vision is the most dominant)
  3. Memory – recalling various knowledge.  We filter what knowledge to process / memorize. (most researched area)
  4. Learning – how to do something (like learning to use a program)
  5. Reading / Speaking / Writing – using language
  6. Problem Solving / Planning / Reasoning / Decision Making – involves reflective cognition

Facebook for mobile

Facebook Your Phone
by Mark Slee

Facebook was invented to make sharing information with your friends easier and better. Mobile phones were invented for pretty much the same reason. People needed an easier and better way to get in touch with each other, and mobile phones made it happen.

We pondered this for a bit, quickly realized that pondering wasn’t making anything awesome happen, and then started building Facebook Mobile. We’re now happy to report that Facebook Mobile has services available for every Facebook user with a phone. Here’s what they are:

  • Mobile Web lets you surf Facebook on your phone just like the normal website… except that it actually fits on the screen.
  • Mobile Uploads lets you send photos and notes to Facebook when you’re out and about. We know from experience that really cool things are likely to happen when you’re not sitting in front of a computer.
  • Mobile Texts lets you send and receive Facebook messages, wall posts and pokes using text messages, plus you can update your status and search profiles from your phone. Remember that time when you needed to call someone, didn’t have their number, but you knew that it was on Facebook? Yeah, that was the worst. Fear no more

Facebook and Students

An Article from The Telegraph:

Lewd Facebook confessions ‘making students unemployable’

Students who make Facebook confessions about boozing and bed-hopping have been warned it could leave them unemployable.

Facebook: Soldiers banned from MySpace and Facebook

Students who make Facebook confessions about boozing and bed-hopping have been warned it could leave them unemployable.

Undergraduates have been swapping tales of binge-drinking and lewd behaviour on the social networking website.

The craze for online confession pages has swept the country with thousands using them to brag about boozing and bonking.

But academic chiefs have warned students that their racy anecdotes could damage their future job prospects.

One Facebook site, Swansea Uni Confessions, has been slammed by the university and its student union.

In a joint statement, registrar Raymond Ciborowski and Students’ Union president Tom Upton said: “We are seriously concerned about the nature and content of these pages.

“Irresponsible use of social media can damage their future employment prospects as companies are increasingly searching for information on job applicants.”

Undergraduates use the Facebook pages to post tales of what they get up to after moving away from home.

Most of the confessions are anonymous – students email their stories to an unknown administrator who then posts it on the internet for everyone to see.

But concerns have been raised over what these shady administrators might do with students information after the messages have been sent.

The statement added: “Students are sharing personal information, including explicit content, with an anonymous page administrator, who has no accountability.

“As a result, participants’ personal details could potentially be made publicly available for viewing by fellow students, staff, public, press, potential employers.

“University regulations clearly state that it is a disciplinary offence to engage in behaviour which could bring the University into disrepute – this includes social media activity.

“The internet and social media are governed by laws relating to defamation and public order, and as a result, there is no such thing as absolute freedom of speech.”


Issues with Facebook pages –
Constant annoyance
Notifications – notifications aren’t even real time (15-20mins after it happens on facebook)
Noises on chat
Join to a group for info but just get spammed
Annoying ads
A lot of stuff going on down the sides (recommended pages and sponsors etc)
