DIAGNOSTICS VIEW
The ShadowSense technology utilizes a number of unique shadow sensors located along the top of the
touchscreen. LEDs are placed along the remaining 3 edges and these LEDs are used to cast light across the
surface of the glass. When a finger or other object, touches the screen, the shadow sensors are able to detect
the angle of the shadow cast by that object. The Diagnostic View allows the user to view, debug and diagnose
any potential problems with the Baanto ShadowSense touchscreen. The various elements of this view are
described below.
Some of the features available in this view are highlighted in the diagram above and described below:
1. CALIBRATION BAR:
The calibration state of the touchscreen is shown in this bar. The touchscreen goes through a
calibration process at boot up and at various times during operation if it detects that calibration has
changed due to environmental conditions. There are four states of calibration that the touchscreen
undergoes, which are described below:
NO COMMUNICATION (RED) – Cannot communicate with the sensor bar
UNCONFIGURED (GREY) – Device has not started calibration
OPTIMIZATION STARTED (YELLOW) – Device is undergoing calibration. For optimal calibration it
should not be touched or handled while in this state.
OPTIMIZATION POST DELAY (LIGHT GREEN) – device has completed calibration and is waiting for
post processing to be completed.
OPTIMIZATION DONE (GREEN) – device has successfully completed calibration and is ready for
normal operation.
