Kyūdō Approach

Kyūdō is the Japanese art of archery. From it we derive the thought that an optimal result follows from an optimal process.

The current goal of Project Kyūdō is to create an optimal theme for the Ubuntu GNU/Linux distribution. In the long run, the theme should be the central piece in an effort to achieve an optimal presentation.

Due to this being a community effort, we don't have the decision power to put things into place. We will offer an alternative and intend to convince by delivering high quality work resulting from a traceable process.

Guide lines

Impression - Kyūdō Briefing

Top Level

  • Enhance the user computing experience by applying balance and harmony to the Gnome Desktop by framing applications in such a manner as to permit the eye to focus without distraction on the content displayed. The desire is an optimal result from an optimal process.

Target Audience

  • Realizing Ubuntu is used by a broad spectrum of individuals, this solution is targeted toward those who spend a significant amount of their professional or personal day at their computer.

Assumptions

  • Some level of customization may be required

    Although the desire is to craft a very usable solution the process assumes some will need to change the outcome to better suite theirs needs. Reasons include but are not limited to:

    • Personalization to achieve user satisfaction and enhance usability
    • Satisfy physical differences in vision and color perception
    • Compensate for environmental differences and viewing conditions
    • Adjustments for hardware differences
  • The Pareto Principle

    Known as the 80-20 rule, the law of the vital few and the principle of factor sparsity states that, for many events, roughly 80% of the effects come from 20% of the causes. It is assumed at any given moment the desire of the user is to focused on an area of the screen which is less than the total amount of available.

  • Asthenopia and Poor Design

    Many computer users experience Asthenopia or visual stress due to:

    1. an increase in the number and complexity of necessary eye movements and focusing skills
    2. poor lighting conditions, glare and distracting reflections
    3. screen flicker rate
    4. the extended amount of computer use

    It is assumed screens designs which aid the eye in focusing on content over a prolong period of time reduce eye fatigue and Asthenopia.

Attributes of the 9.04

  • Faster boot time
  • New notification system
  • Online services

Goals

Transparency to Applications

To be transparent, your eyes should not be drawn to the window frame or the supporting control widgets. Control widgets should be available in a manner which enhances usability and are easily identified as needed.

The Language of Color

HueSatValue.png

Color is the result of some combination red, blue, or green, and presented using hue, saturation, and value.

Hue

Hue identifies the general family of a color, such as red, yellow, blue or green. The traditional color wheel is made up of twelve color families: red, red-orange, orange, yellow-range, yellow, yellow-green, green, blue-green, blue-red-violet, violet and blue-violet.

Saturation

Saturation is how pure the color is. A fully saturated color is the truest version of that color. Primary colors (red, yellow, and blue) are "true", so they are also fully saturated.

Value

Value describes how light or dark a specific color may be.

Gnome Color Wheel

Complementary Colors

Colors on the opposite side of a color wheel are called complementary colors. In combination, these create striking contrasts. For less contrast, choose colors next to each other on the color wheel, which are called analogous colors. Choosing colors of different tints within one color family creates a monochromatic color scheme.

Warm or Cool

Different colors in the same family may be described as being "warm" or "cool." Colors with yellow undertones will seem warmer, while the same color with blue or red undertones will appear cool. Cool colors — blue, green, violet — invite relaxation and thought. Warm colors — red, orange, yellow — encourage conversation and play. Ubuntu colors are warm.

Warm Neutral

If you take the color white and divide it by the color black the quotient is 50% gray or "#808080". Realizing gray is displayed "cool", the task is to identify it's warm counter part.

50% Gray

To warm this color I set the "Hue" to 36 and increased the saturation to "7". Very Ubuntu! Smile :)

Warmed 50% Gray

As you can see the black over powers the tint and demands the brightness be encreased.

Lighten Warmed 50% Gray

Applying a touch of art to the science results in "Ubuntu Gray" which is "Warm" and falls in the middle of the gray scale.

Dancing Around the 50 Yard Line

Putting the power of the theme engine shade function to work the desired outcome becomes a series of analogous colors.

Buttons are colored or shaded as follows:

  • bg[NORMAL] = shade (1.2, @bg_color) # Default @ 20% brighter

  • bg[PRELIGHT] = shade (1.1, @bg_color) # Prelight @ 10% brighter

  • bg[ACTIVE] = shade (1.0, @bg_color) # Active @ default brightness

  • bg[INSENSITIVE] = shade (1.1, @bg_color) # Dimmed @ 10% brighter
