FAQ

1. How do I know the penlight is turned on?	Look into the pen from its light end. The inside turns red when it is on, if it's not red then it is not on. You can also move the penlight on a hole. If the LED on the Starfish turns bright, it means the penlight is turned on.

2. Is the Infrared penlight harmful?	Unlike laser spot or bright light spot, the invisible infrared penlight has little effect on the eyes. In general, if the infrared has any effects, it's usually good because a human body emits infrared light from its biochemical activities.

3. Does daylight affect the Starfish Pointer?	The sun light has a full spectrum of light and the infrared part in it can affect the Starfish Pointer when it is put directly in the sunshine. The Starfish works well in regular office and home environment. If you have a light source with strong infrared component such as a candle light, avoiding facing the Starfish panel directly to the light source should be good enough.

4. Is the pen always on or do I need to keep the switch down?	The push button switch on the end of the pen is just like that in a regular ink pen. Once it's turned on, it stays on.

5. How long can the batteries last?	The batteries shipped with the Starfish package can last about 10 days if it is always on. But during later days, sometimes the current may run out temporarily and seems stopped working. Turning the penlight off for a few minutes and turn it on again will resume the operation.

6. How do I draw curves?	In most graphics software, a curve is drawn by specifying a start point and a end point or a rectangular frame. Starfish Pointer can move cursor to desired locations and perform such tasks. To move cursor in curvature manner, move the light from one hole to another to change the moving direction of the cursor.

7. Sometimes, I can't stop the cursor at the point I want. What can I do to position the cursor exactly.	The holes on the rings move the cursor in different directions at different speeds. Because the pixels on a screen are in X-Y directions, to move the cursor in a slope may need to take different step sizes for the 2 directions. Some holes move the cursor with 2 or 3 pixels per step in one direction with 1 pixel in another direction. Thus it may be difficult to use these holes to move the cursor at an exact point. The best practice has been to use different directions to move the cursor to a close position near the destination, then use holes for the vertical or horizontal directions to go to exact point. Holes point to 45 degree angles are also easier to control as the move the cursor 1 pixel evenly in both directions.

8. Do I need to install any software on my computer?	No, Starfish Pointer is pure plug and play as long as your computer system support standard USB mouse operation.
