Benefits of technology
[0013]Accordingly, the present invention has for its first object a computer workstation with a display device oriented at an inclined angle near the horizontal such that the user can write, sketch or draw on the display screen-tablet surface it a natural manner, where it results in a new and surprising telewriting, teledrawing, and voice-graphics conferencing system.
[0015]A still another important object of this invention is to provide for a human-computer interface that results in a natural, easy to use, and useful computer workstation, personal computer, computer terminal, personal workstation, and / or computer console.
Problems solved by technology
However, the prior art fails to anticipate the importance of computer workstation with computer, graphic tablet, and display device, with inclined screen angle and its adjustability through large angles.
However, the disclosure does not recognize display screen angle adjustability and does not teach a computing means of any type, which severely limits the usefulness of the device.
Although the CRT display can be retracted to a stored position below the work surface area, the teachings of Brown do not disclose a graphic tablet and do not disclose screen angle adjustability.
The reference teaches adjustable mounting only for glare reduction, and does not disclose a graphic tablet or a computer; thus also restricting the terminal to non-graphic input.
Again, the prior art does not anticipate graphic input or screen angle adjustability for optimal stylus control.
No prior art can be found that disclose screen angle adjustability from horizontal to vertical, with a graphic tablet and computer.
An important problem exists if the screen angle is near vertical.
In addition, if the screen is at eye level, as with most prior art, the user's arm must be raised and held at position that will become very tiresome to the user, if used for a significant amount of time.
These shortcomings have severely restricted the use of standard graphic tablet input devices in the marketplace.
However, the mouse graphic input devices also have several disadvantages.
First, it is difficult for the user to write, sketch, or draw with a mouse, because the device is too large and bulky to act as a pen or stylus.
Secondly, the device must have a clear area on the table or desk for the unit to slide.
This is valuable work space that some workstations cannot afford to lose.
Prior art workstations are inherently limited in their graphic interaction capabilities.
The use of mice, joysticks, trackballs, and touch panels all have limitations for entering positional and functional data.
The prior art also does a poor job at providing a fatigue free workstation.
The prior art workstations do not provide the means to accomplish that type of communications.
In addition, conventional prior art workstations do not provide the ergonomically designed hardware support necessary for real-time electronic mail communications, while connected to either in Local Area Network communication means or remote communication means.

Embodiment Construction
[0025]The disclosed invention can be described with reference to the perspective view of FIG. 1, which shows one possible embodiment. The components of the computer workstation may be arranged in several different embodiments. In FIG. 1, a table support 26 physically supports a display device 22, a transparent graphic tablet surface area 18, a stylus 14, a computer keyboard unit 12, a mouse unit 15 and a computing means 24. The table support 26 may be a standard desk or pedestal, modified to physically support the above components, or it may be a specially design structure. All display devices define a display screen of a finite area. The display device 22 has a display screen 16, which is located under the graphic tablet surface 18 and is of equivalent size, as indicated in the figure. The display screen is inclined at an angle between the horizontal and 45 degrees. The angle of inclination is adjustable through a wide range of angles. The display device 22 has control circuitry wh...

A man-computer-man communications system, including a computer workstation (10), which is comprised of a display device (22), graphic tablet (18), stylus (14), computer unit (24), and display device screen (16) located at convenient locations. The active area of the graphic tablet is a transparent surface area (18), which is coincident to the display screen and is approximately the same size as the display screen. The graphic tablet device may include active or passive stylus (14). A keyboard unit (12) and telephone unit (28) may be added to the workstation. An external communications system may be added to transmit and receive data to or from remote computers or other workstations. The computer unit (24) controls the operation of the workstation and external communications.
Description
CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation of application Ser. No. 11 / 023,361 filed Dec. 29, 2004 (pending), which is a continuation of application Ser. No. 08 / 487,778 filed Jun. 7, 1995 (abandoned). Each of the foregoing applications is incorporated by reference in its entirety.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]This invention relates to communication systems used by individuals for general tele-writing, sketching and drawing of hand written information, to be transmitted to other individuals via computer systems. In particular it relates to computer workstations comprised of electrical and mechanical devices for the input, computation, and output of data, resulting an integrated ergonomically designed human-computer interface system.[0004]2. Description of the Prior Art[0005]In the following, a computer workstation is defined to be a combination of devices and apparatus, which may include computer hardware and softw...
