In handwriting mode the stylus is recognized for a short period of time so you get a partial line and then the screen stops recognizing the stylus probably thinking it is invalid input.
Using a stylus is necessary in order to be able to place highlighting accurately and for the handwriting features of the i62HD.
Please let me know how I can go about getting this corrected.
the IR Multi Touch technology of i62HD was developed to scan for thicker objects (like your finger e.g.) near of the screen. Just imagine a net of invisible IR rays near of the screen surface. Here you can see the the size of the raster of the IR LEDs:
Boox is just calculating coordinates of your fingers based on interrupted rays.
Just try out a pen, which is similar to a finger
