OptiTUIO Calibration: Main Interface Settings Tab

Devices Tab Configuration

Once a sensor is added under the Devices tab in the configuration utility, settings are available in the properties panel on the right:

• Name: Assign a custom identifier to the sensor.
• Connection: Defaults to Network. If using a USB sensor (like the Hokuyo URG04 or OT-500), change this setting to Serial.
• Offset X: Moves the sensor origin coordinate left or right in millimeters.
• Offset Y: Moves the sensor origin coordinate up or down in millimeters.
• Rotation: Adjusts the sensor angular alignment (Z rotation) in degrees.
• Kalman: Controls the signal noise filter. This adjusts the maximum deviation of measured coordinates. It is recommended to use the default values.
• Smoothing: Adjusts interpolation. A higher smoothing value reduces input jitter but introduces noticeable latency.
• Screen: Assigns a previously created interactive screen template to this sensor.
• Flip X / Y: Flips coordinates along the X or Y axes depending on physical mounting orientations.

Advanced Settings

Advanced configurations can be accessed by clicking the Advanced button in the device control bar.

• Bilateral Filter: Reduces noise/errors detected very close to the sensor boundary. Disabled by default.
• Margin: Extends the active touch recognition area slightly beyond the boundary of the physical screen coordinates.
• Max. Touch Deviation: Specific threshold filter. Do not change this value.
• Min. Touch Segments: Specifies how many sensor detection rays must target a physical object before it is registered as an active touchpoint (Default is 3).
• Min. Touch Age: The duration (in frames) a touch point must persist before being transmitted to output receivers.
• Record Option: Used for support cases. Clicking Record saves raw data files of the tracking process. This file can be shared with Interactive Asia Co. Ltd. to troubleshoot tracking anomalies.
