If you want to drawing freehand images directly onto your computer, then you need a digitizer tablet. It functions like a touch screen commonly used for tablet PCs except that it has a blank screen and is more sensitive to pressure. You can directly draw on the tablet with a puck and stylus, a pointing device that has over 16 control buttons for adjusting the image attributes of your drawing. Your drawing won't appear on the tablet itself, but it will appear on the computer screen.
Digitizer tablet models - Which is better?
Digitizer tablets have different models and most of them are able to draw thicker lines when you increase your stroke pressure. There are also high-end tablets capable of drawing features that are more realistic, with paint splatters and ink drips.
1. Command size digitizer tablets - Commonly used for diagrams, freehand drawings and graphic design, they can be installed on your desktop or placed on your lap. Sizes ranges from 4x5 to 12x12 inches (the smaller are handheld).
2. Tracing size digitizer tablets - This is for bigger drawings like architectural plans, blueprints, and large posters. Its size ranges from 24x36 to 36x60 inches and they can be mounted on stands, hung on walls, or rolled up.
What to check
Buying a digitizer tablet may seem hard at first, but there are really only two things you should look for.
1. Screen format - Ensure that the tablet can match the aspect ratio of your monitor. Most of them are designed for common 4:3 monitors, but they can distort your images when used with newer ones. Look for one that can support wide-screen or dual monitors if you have such a monitor.
2. Footprint - If you want better resolution, it is advisable to choose a digitizer tablet with bigger relative footprint.
