Hello

World

Hopefully navigating these web pages is reasonably intuitive. As I have sometimes struggled to understand other people's "intuitive" interfaces, I though it best to give a brief tutorial of my intuitive design practices.

A typical page looks something like this: If you move the mouse, or move your finger on a touch display, you should see five square control buttons show up at the bottom of the display on wide (landscape view) screens On narrow (portrait view) screens, the control buttons may show up along the left edge You can click, or tap, on the square buttons to get the following actions:

• House Icon - Return to the home page (this one).
• Bullet List - Go to the table of contents page
• Left Arrow - Go to the previous page (as listed in the table of contents)
• Right Arrow - Go to the next page (as listed in the table of contents)
• Crossed-out Eye - Hide these control buttons from view

The control buttons are on a timer, and should disappear after a few seconds. This should make it easier to read the entire page. Every time you move the mouse, or tap a touch screen, but buttons will reappear. If you find the buttons annoying, you can hide them by clicking/tapping on the crossed-out eye button. After you do that, the large buttons will stay off the screen.

If you have hidden the buttons, there are two ways to get them back. The first, is to tap on the small square button with the eye icon, that still appears in the lower left hand part of the screen when you move the mouse, or tap on a touch screen Your other option, is to scroll all the way to the bottom of the page. The control buttons will always show up at the bottom of the page, and cannot be hidden when they show up there.

Many of the images and equations will be too small for you to clearly view all the details. You can click the mouse, or tap the screen, on any image or equation. Tapping/clicking on an image/equation will force your web browser to open a new window, or new tab. The image or equation will then be displayed using the full size of your screen. Moving or tapping on the screen will bring up some square control buttons in the upper left hand portion of the screen The buttons have the actions listed below. There are also mouse movements and touch screen gestures which can give you these actions:

• Zoom in - Click or tap on the square button with the magnifying glass with the + symbol in it. If you have a mouse, the scroll wheel can also be used. If you have a touch screen, the two-finger touch zoom gesture can be used.
• Zoom out - Click or tap on the square button with the magnifying glass with the - symbol in it. If you have a mouse, the scroll wheel can also be used. If you have a touch screen, the two-finger touch zoom gesture can be used.
• Pan - There is no button to pan up/down/left/right. However, you can do these actions with your mouse or touch screen. Just click-and-drag with the mouse, or touch and drag with your finger on a touch screen. The entire image should move in the direction you drag it.
• Home zoom/pan - If you want to return to the original zoom and pan setting, click on the square button with a house icon. There are no mouse or touch-screen gestures to do this, only clicking on the square button will return you automatically to the home view.
• Close Browser Window/Tab - The square button with the X in it will close the window, or the browser tab, showing the image. There is no mouse movement or touch-screen gesture to do this.

The table of contents lists every page that can be viewed in this set of documents. They are arranged in folders, much like files on a typical computer operating system. If see a folder icon to the left of a label, it means there are additional pages which can be seen by clicking on the folder If you want to hide the pages in a folder, just click on the folder icon again to collapse the view down There are two ways to leave the table of contents page. The first, is to click on the page icon to the right of a heading. That will take you to the page referenced by the heading The other way to leave the page, is to click on the large square button at the bottom of the page. As always, that will return you to the home page.

If you have any comments on this, good or bad, I'd like to hear them. While I enjoy the good comments more, the bad comments are more useful. You can contact me by email at: kurt.kosbar@gmail.com
