Controller properties
The Properties dialog defines device properties.
Function				Description
				Associates a name to the device. By default the name is the driver’s controller device name.
				Applies a filter to produce smoother drawing. Software implementation of a low pass filter algorithm to remove jitter. This is a more advanced approach to filtering that can improve drawing but will affect the speed of drawing the higher the value used.
				The Lift off Time value specifies the time interval required to register a stylus lift after the last touch packet is received. Lift off time is defined in units of 20ms. This value is used to perform a pen up if the ‘Use Lift off’ packet is disabled otherwise Pen ups are generated as soon as the stylus leaves the pointer device display. However, because this timer is triggered after each received touch packet it is important to ensure the value is greater than the time interval between data packets otherwise pen up events will constantly be generated. If this value is set to zero pen ups based on time are disabled. This is a useful setting for controllers working in Delta mode, that is, data is not generated unless the x or y co-ordinates change.
				Stabilization causes small movements to be ignored.
				Applies a filter to produce smoother drawing. Averaging takes the average of the last N co-ordinates. This is a very basic approach to filtering that can improve drawing and not affect drawing speed.
Priority
				In a multi pointer device environment this setting indicates the priority given to the device: Interlock: The device can only be used if no other device is in use (i.e. touch screen being touched) and the time since the last use of another device exceeds the ‘release time’ period. Release time is defined in units of 20ms and defaults to 20ms. Admin: Any device currently in use is forced into a ‘pen up’ state and the device is given immediate priority.
				Defines the interlock release time, as described above.
				Only shown if a pen up data packet is generated by the device on stylus lift off. If enabled the pen up data packet is used to invoke pen up otherwise the pen up processing will generate a pen up event at the lift off time threshold as described above.
				The Anchor Mouse option is set if the mouse cursor is to return to its original position after the pointer device has been used. Normally used in multi-monitor configurations where the cursor is to return to another monitor.
				Indicates if the device is enabled. If the device is disabled the hardware port’s resources are available for use by another device or process. This is a way of freeing up the resources without having to uninstall the driver. One example of this is where a serial to USB converter is used and the device needs to be ‘stopped’ before it can be safely unplugged from the system. If UPDD has a connection to the device it cannot be ‘stopped’ until disabled by UPDD.
				Less common, advance features, enabled as required:
	Edge Acceleration			Settings whereby cursor accelerates towards the edge of the screen when stylus moves towards the edge. Useful if cursor needs to slide off desktop to invoke a system function, such as hidden task bar that is shown when cursor is pushed off edge. The Height and Width settings are based on a 65535 x 65535 logical desktop area (3000 works well). The gain value is the movement accelerator (20 works well). Only works for primary monitor. In some environments the edge acceleration function may result in the cursor moving beyond the calibration area in which case the ‘Ignore touches outside the calibrated area’ should not be set.
	Ignore touches outside calibrated area			Touches generated outside a calibrated area can be ignored e.g. a touch screen is larger than the video display area which may be used for UPDD Toolbars only. If set, when this area of the screen is touched the touch is ignored.
				Mac OS X only - Enabled if the touch screen is used to run classic mode applications. With this enabled the driver is optimized for classic mode but will still work in native mode and changes the way mouse clicks are fed into the OS. If this is incorrectly set for the mode in use it is possible to lose the occasional touch when tapping the screen fast.
				Mac OS X only - It was discovered that with Mac OS 10.3.6 the low level OS driver interface does not correctly handle mouse emulation if keyboard keystrokes are being used with mouse clicks e.g. ‘CTRL mouse click’ to select multiple items. This may be corrected in later versions of Mac OS X. If you experience this problem enable this setting. When enabled the driver uses a different OS driver interface that overcomes the problems seen with the low level interface. A system reboot is needed for this new setting to be activated in the driver.
				Mac OS X only - The driver can automatically adjust calibration if the system is switched between Landscape and Portrait views. Landscape is always 0° but Portrait can be either 90° or 270° and this is selected in the System Preferences Display dialog. Unfortunately we have not found a way to programmatically determine the degree of rotation as selected in the Display dialog so it has to be manually defined here such that UPDD can sync calibration once the system is set into Portrait. Given that UPDD does not know when the screen is rotated, the rotate logic is triggered when the video resolution is set in the rotated mode to represent Portrait mode – does not happen automatically as one would expect (e.g. 1024 x 768 is changed to 768 x 1024). See Rotate document for additional rotate information.
