Currently, the OSD and human interface in projectors is very un-intuitive and unnecessarily complex. They do not allow for a way to meet the government accessibility requirements. By allowing for enhanced user interaction, and adding user feedback, the human interface can be improved. This paper describes a set of specifications and requirements that will work with multiple projector core chipset manufactures to describe a common firmware interface and action feedback mechanism. This improves over current solutions by increasing usability, adding more flexibility, and commonality across the projector industry.

Human Interface Improvements for Display Projector Management

The idea is a set of requirements and implementation details. This extends current interface of digital projectors to allow improved operation of the unit. Improvements and new work have been done for:

- Unique Icons - Unique Menu Parameters - Improved Font - User Feedback - Additional status information - Follows IBM "Think" color scheme

There has already been a push from the industry to adopt this proposed human interface mechanism into a standard.

1) Placement

a. Display panel

By default, the menu will come up centered left to right and top to bottom. The user has an option to adjust the screen position. The display panel will be 640 pixels by 480 pixels in size.
b. Tabs

Across the top of the display panel will be available tabs. Each tab will contain a menu with icons.
c. Menus

Once a tab has been selected, the associated menu will be displayed from that tab.
d. Icons

Certain menu items will have associated Icons
e. User Feedback

The feedback panel is across the bottom of the display panel.

2) Colors

a. Background

The Background of the displayed menu will be black.
b. Inactive Selection Color

Inactive tabs have a white font on a grey background. Inactive menu items have a grey font on a black background.
c. Unavailable Selection Color

Tab items that are not available to be selected will be shown in a dark grey. Unavailable menu items will be shown a 50% darker grey.
d. Active Selection Color

Active tabs have a green font on a black background. Active menu items have a green font on a black background.
3) Menus

All menu icons are to be in white on a black background, and will be square. The icons will be no less than 25 pixels in height, and no more than 40 pixels in height. The icon color will follow the font colors in terms of connection
