SigmaSense’s TruePressure™ has unlocked truly ground breaking performance in the world of active inking and the ultra-realistic writing experience.
The use of computers in today’s classrooms, even with all of their intrinsic benefits, diminishes the cognitive development in our children below the level that can be achieved with pen and paper. In fact, research is now indisputable on this point.
One of the greatest gifts we can give our children is the cognitive ability to solve problems. Digital handwriting is essential to developing a generation of advanced problem solvers.
TruePressure is the amount of force applied from the pen to the touchscreen, regardless of pen orientation. This cannot be achieved simply by measuring Axial pressure (as our competitors do).
Measured in 4 axis of the pen – X & Y (1), Z (2), and barrel roll (3) -, it is vertical to flat tilt with no loss of precision. The advanced barrel rotation
allows for various pen/ink shapes (ex. chisel point).
Features
– Location tracking speed transmitted @ 300 pps
– Tip pressure information and other control signals transmitted @ 100 pps
– Bi-directional control channel between sensor and pen
– Orthogonal communications signals for self and mutual
– Pen ID assignment
– Transmission of pen serial number to sensor
– Availability of alternate tracking frequencies
– Pen button and indicator states
– Accelerometer data from pen (angle, roll, etc.)
– User preferences (ink type, color, etc.)
– Authentication of the pen for system security
