Advantages |
Low cost, Superior image, high resolution (3 to 16 million points), can be scaled to almost any size, can detect almost any object |
No overlay, Superior image, can detect any objects which block IR light. |
Low cost (for small sizes), can detect any object |
Moderate cost, good in harsh environments |
Can be deployed to a curved surfaces |
|
|
Disadvantages |
|
Expensive, detection placed above screen and sensitive to ambient light |
High costs for large areas, very sensitive to scratch, low fidelity and reduces the visibility of the screen |
Finger activation only, reduces illumination, finger must stay in position for detection so no movement |
Delicate, expensive and sensitive to scratch |
