Figure 1 — Typical graphics tablet hardware

Graphics tablets have high resolution, but the effective drawing area is quite small ranging

from 25 % of the overall size for an A6 area to 50 % of the overall size for an A4 wide drawing

area. The tablets are heavy too see Figure 2. For a drawing area that is the size of US letter

paper (8.5 in x 11 in) the overall tablet size will be about 12.5 in x 16 in and would weigh

around 4 lb.

Figure 2 — Graphics tablet size and weight

Artists graphics tablets with a 4”x5” drawing area can be bought for under 100 $. Larger 6”x8”

drawing area can be bought for about 200 $. The problems for unfamiliar users is the small

drawing area resulting in amplified the pen movement on the screen, and the pen position

coordination with the drawing as the pen position has to be judged from the PC screen.

2.2 Digital Pads (Interactive paper)

Many people prefer pen on paper input because it is natural and what they are used to. Paper

is easy to navigate, people see the result and it can be further annotated. A digital pad uses a

standard paper pad, mounted on an electronic sensor panel and a special pen. The pen takes

standard ink refills and has a small transmitter sensed by the panel to electronically record

the writing in memory. An example of digital pad is the AceCad Digimemo

(http://www.acecad.com.tw/dma502.html) see Figure 3. The cost for a letter sized digital pad
