The psychologist Mihaly Csikszentmihalyi (1990) has described focused attention as “psychic energy”. Like energy in the traditional sense, no work can be done without it, and through work that energy is consumed. Most of us have experienced a mental/emotional state where all of our attention (or energy) is totally focused on an activity. Csikszentmihalyi (1990) named this state “flow,” based on how participants in his studies described the experience.
flow state can be classified into the three areas; 1. Causes of Flow 2. Characteristics of Flow 3. Consequences of Flow (Novak, Hoffman and Yung, 1999)

- A clear goal
  Immediate feedback on the success of attempts to reach that goal
  A challenge you’re confident you have the skills to handle
- Loss of consciousness of self
  Distortions in the perception of time
  Activity is perceived as intrinsically rewarding
- The main elements designers can control are:
  Providing immediate feedback
  Balancing the perception of challenge against users’ skills
- he user navigates to accomplish a task, like seeking information on a particular topic or surfing for fun
- receives quick, sensory feedback in the form of a visual shift and/or sound from links, buttons, menus, or other navigation items.
- The opportunities for action are balanced with the user’s ability. At a basic level, this is accomplished by providing an uncluttered interface and eliminating unnecessary information to limit the user’s cognitive load.
- Flow and Emotion
- Flow tends to occur in situations with higher levels of challenge and skill. If the challenge is too easy, or user skill levels are very high, anxiety can be so low that there is little motivation to do anything. This level of activation or “arousal” in the body is the physiological (i.e., bodily) dimension of emotion. The level of arousal affects how intensely we experience a given emotion, and intense emotions demand our attention. In evolutionary terms,
- Both pleasant and unpleasant objects and experiences can increase arousal levels. Frustration and the excitement both increase arousal levels. So do large images, bright colors, and high contrast (van Gorp, 2006).
- Goal-directed vs. Experiential Use
  Different motivations for using a website require different designs to facilitate flow (Novak, Hoffman and Yung 1996). Novice users tend to see the Internet in a playful way, while more experienced users tend to view the Internet in a more utilitarian way (King 2003).
- Novice Users – Experiential use
  Less challenging
  More exploratory
  Entertainment-oriented
- Experienced Users – tendency towards Goal-directed use
  More challenging
  Less exploratory
  Connected with tasks (e.g. research, work and shopping)

- HTML tools have a high overall score, with site wide revision being
  the major problem
  Diagramming doesn't score high on any criteria, and is considered
  particularly poor at supporting site wide revisions and simulating
  advanced functionality
  The respondents using a presentation tool find that their tools
  are very easy to use and suitable for presentation and setting up pages
  Respondents using non-computerized tools feel hat the approach fall
  short when having to do site wide revisions

1. Cooper based his persona on a real person he’d actually met, talked with, and observed.
2. Cooper didn’t start with a "method"—or especially not a "methodology"!

- 3. The persona wasn’t a document. Rather, it was the activity of empathetic role-play.
- 4. Cooper was doing this in his "spare time," away from the system, away from the cubicle.
- 5. His persona gained clarity by focusing on a particular person—"Kathy".
- Personas are actually the designer’s focused act of empathetic imagination, grounded in first-hand user knowledge
- 1. Documentation as a container of knowledge, to pour into the brains of others.
- 2. Documentation as a substitute for physical production.
- 3. Documentation as an artifact of collaborative work and memory.

Personas and Goal-Directed Design: An Interview with Kim Goodwin

emphasizes identifying goals of users
before doing any formal design.
"Who's really using
this, and what do they really want to accomplish?

- they are powerful design, measurement, and communication
  tools.
- the technology industry is doing things
  backwards
- If you start with a deeply
  flawed design, usability testing will diagnose many of the problems, but won't
  necessarily point to a cure. Iteration won't get you to a great design
- That moment of conceptualization is an intuitive leap
  I don't think any methodology can replace. The Goal-Directed methodology reduces
  the size of the leap and provides tools for evaluating the quality of the result--in
  that sense, I think it's probably better for inexperienced designers than some
  other methods.
- Because any application designed for
  the web can be distributed almost for free, companies take that as permission
  to launch products or services in "web time," without really thinking
  through the business plan, the design, or a whole host of other crucial factors.
