Customised aggregation of cards / tiles

January 15, 2014

The (customised) aggregation (of tiles on a page) depends on:

  • The person consuming the content and their interests, preferences, behaviour.
  • Their location and environmental context.
  • Their friends’ interests, preferences and behaviour.
  • The targeting advertising eco-system.

Cards are fast becoming the best design pattern for mobile devices

Mandel: The Golden rules of interface design

May 16, 2011

Place Users in Control

  1. Use modes judiciously (modeless)
  2. Allow users to use either the keyboard or mouse (flexible)
  3. Allow users to change focus (interruptible)
  4. Display descriptive messages and text (Helpful)
  5. Provide immediate and reversible actions, and feedback (forgiving)
  6. Provide meaningful paths and exits (navigable)
  7. Accommodate users with different skill levels (accessible)
  8. Make the user interface transparent (facilitative)
  9. Allow users to customize the interface (preferences)
  10. Allow users to directly manipulate interface objects (interactive)


Reduce Users’ Memory Load

  1. Relieve short-term memory (remember)
  2. Rely on recognition, not recall (recognition)
  3. Provide visual cues (inform)
  4. Provide defaults, undo, and redo (forgiving)
  5. Provide interface shortcuts (frequency)
  6. Promote an object-action syntax (intuitive)
  7. Use real-world metaphors (transfer)
  8. User progressive disclosure (context)
  9. Promote visual clarity (organize)

Make the Interface Consistent

  1. Sustain the context of users’ tasks (continuity)
  2. Maintain consistency within and across products (experience)
  3. Keep interaction results the same (expectations)
  4. Provide aesthetic appeal and integrity (attitude)
  5. Encourage exploration (predictable)

From the chapter ‘The golden rules of interface design’ in: Theo Mandel, ‘The Elements of User Interface Design’, 1997

Dashboards

June 22, 2010

“Dashboard UI’s are designed to provide rapid contextual information regarding some higher task or goal, to which the majority of the user’s attention is directed. This stands in high contrast with regular desktop applications, where the UI is (usually) designed to fulfill a specific task or goal in itself.”

Kurt Schwitters: Gesetze der Bildform

May 15, 2010

Visiting the exhibition Van Doesburg and the International Avant-Garde at the Tate Modern, I was struck to see something like a website wireframe in a small book from 1930, ‘Gesetze der Bildform’, by the modernist artist Kurt Schwitters.

Kurt Schwitters: Gesetze der Bildform

Kurt Schwitters: Gesetze der Bildform, 1930

On these two pages he compares / contrasts orientation with advertising.

Orientation / Advertising … (Orientierung / Werbung)

  1. Static / Dynamic … (Ruhend / Bewegt )
  2. No center, balanced, hence stable / Distinct center, hence radiating … (Ohne Mitte, daher ausgeglichen / Betonte Mitte, daher austrahlend)
  3. Passiv / Aktive … (Passiv / aktiv)
  4. Objektiv / Subjective … (Objektiv / Subjectiv)
  5. Vertical, horizontal, rectangular forms / Parallel, any shape … (Senkrecht, waagerecht, Vierecke / Parallel oder schraeg, jede beliebige Form)
  6. Parts of the same type; the negative of each part is essentially the same as its positive / Parts of different types. Negative and positive are essentially different, like conkave and convex … (Teile gleichartig; das Negativ jedes Teiles ist im Wesen gleich seinem positiv / Teile verschiedenartig; Negativ und Positiv sind wesentlich verschieden, wie konkav und konvex)
  7. hence – providing orientation / hence – advertising, aggressive … (also – orientierend / also – werbend, aggressiv)

Visually structured v plain language information

April 20, 2010

My comment in response to Jeff Johnson’s book/article: Designing with the Mind in Mind

I do agree that visual structure is key to clean and scannable interfaces but this insight is often being challenged in usability test sessions. Presenting information in a purely structurded way implies some level of abstraction that many users (particularly casual ones) cannot follow easily as it makes them ‘think’. And this is what UX designers want to avoid by all means :-).

People often prefer plain language information, phrased in full sentences. My guess: it’s because a sentence is more explicit and is better suited to mimic a conversation (which successful HCI is all about).

This does not hold true for any site and any type of information and it doesn’t undermine the good principles that you’ve outlined here. But it shows that minds work differently and many people want to be addressed in a more direct (as you call it) prose style.

    Narratives in Screen Design

    November 24, 2008

    With narratives in mind, you can think of possible routes for your work and design meaningful and rich interaction:

    • From start to finish
    • From general to specific
    • From viewing to reading to doing
    • From You to Me

    The trade-offs between elements adjacent in space versus stacked in time

    July 10, 2008

    The trade-offs between elements adjacent in space versus stacked in time are always in the mind of a UI designer. Placing many elements on the same screen reduces the need for navigation and gives users a comprehensive feeling of “it’s all at my command.” Moving focus from one element to another is instant and seamless. On the flip side, separating elements onto different screens slows things down with navigation while increasing clarity. There is more room for explanation and luxurious space when fewer elements occupy the page. The eye has less to filter through. The course of action is more obvious.

    Gestaltpsychology

    June 6, 2008
      Gestaltpsychology is a range of design principles about how elements group together. The principles go back to the seminal work by Max Wertheimer “Untersuchungen zur Lehre von der Gestalt” in Psychologische Forschung, 1923, vol.4, and are based on the law of ‘Prägnanz’ (pithiness), which proposes that a set of ambiguous elements (elements that can be interpreted in different ways), will most probably be interpreted in the simplest way.

    1. Proximity: Elements that are closer together are perceived to be more related than elements that are farther apart.
    2. Similarity: Elements that are similar are perceived to be more related than elements that are dissimilar
    3. Enclosure: Elements that are enclosed by anything (line, colour or alike) are perceived as belonging together
    4. Continuity: The mind contines visual, auditory, and kinetic patterns.
    5. Closure: A tendency to perceive a set of individual elements as a single, recognizible pattern
    6. Figure-ground: Elements are perceived as either figures (objects of focus) or ground (the rest of the perceptual field).
    7. Connection: Elements that are connected (e.g. by a line) are perceived as a group.
