Font Size Control

Version 1.1 function
Last update: 2/03/00

Visual Guide:

Change font-size control as implemented on the Web Browser Bar

Change font-size control as implemented on the Cached Content Browser Bar

Usage Scenario:

A user with impaired vision finds that the standard font-size on the i-opener is too small to read comfortably. The user moves the pointing device to the "font magnifier" control on the Web browser or the cached content browser, presses the increase font-size button (the "+" symbol) once or twice to increase the size of the font by one unit with each press. Finding that the size of the font is just right, the user resumes reading a Web page in the browser. Another user in the household may go to another Web page and find that they want more of the text on the page displayed at one time so they press the decrease font-size button until the text is displayed to their liking.

Functional Behavior:

• There are five font-size settings supported with the control (largest, larger, medium, smaller, smallest); they correspond to HTML sizes of 2, 3, 4, 5 and 6.
• The default setting is to medium (4)
• Font size is decreased with each press of the "-" button on the control set up to the point that the font-size will not get any smaller
• Font size is increased with each press of the "+" button on the control set up to the point that the font-size will not get any smaller
• The "ABC" text between the "-" and "+" buttons serve only as a label for the buttons
• While on the smallest font size, grey out the "-" button, and while on the largest font size, grey out the "+" button

Keyboard Shortcuts:

• Font size increase = Ctrl + up arrow
• Font size decrease = Ctrl + down arrow
  

Assumptions:

• There will not be a control for text font size in the Mail and Address Book applications; font size control is only for content in the Web browser and the cached content browser.
