| Scanning Range | 10-1·mm | Mechanical Data (col. B * 10) | The area (width and height) the Touch Sensor Module (TSM) will scan for an object with lasers and photodiodes (PD). This value also sets the limit for High Y (Max Y) below. | |

Low Bound X (Min X) | 10-1·mm | 36 | Start position of the Touch Active Area (TAA) in X-direction. Low X, High X, Low Y & High Y make up the TAA. | |
Low Bound Y (Min Y) | 10-1·mm | 0 | Start position of the Touch Active Area (TAA) in Y-direction. Low X, High X, Low Y & High Y make up the TAA. | |
High Bound X (Max X) | 10-1·mm | Mechanical Data (col. A * 10) + 36 | End position of the Touch Active Area (TAA) in X-direction. Low X, High X, Low Y & High Y make up the TAA. | |
High Bound Y (Max Y) | 10-1·mm | Mechanical Data (col. B * 10) | End position of the Touch Active Area (TAA) in Y-direction. Low X, High X, Low Y & High Y make up the TAA. | |
Reverse X | True/False | Boolean | False | Reverses the X-coordinates of reported touches. Note, that the origin of the vast majority of the displays is in the top left corner. |
Reverse Y | True/False | Boolean | False | Reverses the Y-coordinates of reported touches. Note, that the origin of the vast majority of the displays is in the top left corner. |
Flip XY | True/False | Boolean | False | Swaps the Y- with the X-coordinates of the reported touches. |
Offset X | 10-1·mm | 0 | Offsets the projected TAA in X-direction, on the display. | |
Offset Y | 10-1·mm | 0 | Offsets the projected TAA in Y-direction, on the display. | |
| HID Display Size | The size of the display reported by the Touch Sensor Module to the host. Only usable when connecting with USB HID | |||
Hid Display Size X | 10-1·mm | Mechanical Data (col. A * 10) | Width of the physical display. It is very important to set this parameter correct since the TSM will report touch coordinated in percentage of the physical display length/height. | |
Hid Display Size Y | 10-1·mm | Mechanical Data (col. B * 10) | Height of the physical display. It is very important to set this parameter correct since the TSM will report touch coordinated in percentage of the physical display length/height. | |
| Snapping | Configure the snapping area around the edges of the Touch Active Area (TAA) | |||
| Enabled | True/False | Boolean | False | Enables or disables the snapping filter. |
| Left Inner | Mechanical Data | 10-1 mm | 0 | Distance from edge to the inner snapping edge, left side of TAA. |
| Left Outer | Mechanical Data | 10-1 mm | 0 | Distance from edge to the outer snapping edge, left side of TAA. |
| Right Inner | Mechanical Data | 10-1 mm | 0 | Distance from edge to the inner snapping edge, right side of TAA. |
| Right Outer | Mechanical Data | 10-1 mm | 0 | Distance from edge to the outer snapping edge, right side of TAA. |
| Top Inner | Mechanical Data | 10-1 mm | 0 | Distance from edge to the inner snapping edge, top side of TAA. |
| Top Outer | Mechanical Data | 10-1 mm | 0 | Distance from edge to the outer snapping edge, top side of TAA. |
| Bottom Inner | Mechanical Data | 10-1 mm | 0 | Distance from edge to the inner snapping edge, bottom side of TAA. |
| Bottom Outer | Mechanical Data | 10-1 mm | 0 | Distance from edge to the outer snapping edge, bottom side of TAA. |
| Click On Touch | Configures the Touch Sensor Module to send an Up (touch event) after Down within a defined threshold to create an instant touch experience | |||
| Enabled | True/False | Boolean | False | Enables and disables the Click On Touch Feature |
| Time To Up | ms | 100 | Time from the Down event until the Up event is sent. | |
| Distance | 10-1·mm | 100 | Distance from the initial location that a touch must stay within for Click On Touch to be enabled for a touch | |
| Floating Protection Settings | Wait for the object to stabilize on the Y-axis, in order to identify the position of the object in a reliable way. This parameter should not be set at the same time as Double-Click Prevention is turned on. | |||
| Enabled | True/False | Boolean | True | Floating protection enabled. |
| Floating Protection Time | ms | 40040 | Time to wait before reporting touch registration. | |
| Double-Click Prevention Settings | Configuration of the filter prevention area and timeout. This parameter should not be set at the same time as Floating Protection is turned on. | |||
| Enabled | True/False | Boolean | False | Enables or disables the double-click prevention filter. |
| Prevention Time | >0 | ms | 500 | The time period when no additional touches will be reported in prevention area. |
| Prevention Radius | >0 | 10-1 mm | 220 | The radius of the area around the touch defining area where touches are suppressed. |
| Object Size Restrictions | Only reports touches with an object size that is within the defined limits | |||
Max Size Enabled | True/False | Boolean | False | Allows a maximum touch object size. |
Max Size | 10-1·mm | 0 | Max limitation of a touch object (if Max Size Enabled =True). | |
Min Size Enabled | True/False | Boolean | False | Allows a minimum touch object size. |
Min Size | 10-1·mm | 0 | Min limitation of a touch object (if Min Size Enabled =True). | |
| Miscellaneous Settings | ||||
Number Of Reported Touches | 1-10 touches | Quantity | 2 | The number of touches that can be reported simultaneously. |
| Reflective Edge Filter | True/False | Boolean | False | Useful when there is a risk that there are highly reflective materials right outside the active touch area |
...
Time from the down event until the up event is sent. Setting this to 0 completely disables the possibility to do swiping gestures (or drawing). Setting this to e.g 100ms 100 ms gives the end user 100ms 100 ms to move outside of the set Distance (described below) and begin the swipe gesture instead.
...
This value indicates how long this filter would need to validate the first reported touch. Default value is 400 40 ms. With a lower value the risk increases that a false touch would be reported, and the opposite with a higher value.
