Generic Properties

NameProperty descriptionConstraintsTypeUpon change
Browser Settings
Web AddressDefines the web address of the page shown in the browser.String
ZoomDefines the zoom percentage for the loaded webpage.Int32
Is Input EnabledDefines whether a participant can interact with the web browser. If the value is false, the browser works in the 'view-only' mode.Boolean
Hide On LoadingDefines whether the browser viewport gets hidden during the page-to-page navigation. The mode is useful for eye-tracking studies but may cause hangs , until a new webpage is completely loadedBoolean
Browser Commands

Go Forward NowBoolean

Runtime Status
Triggering TimeReturns the local event time when the current webpage is fully loaded. The element gets triggered, each time as it happens.clTime
Is TriggeredIndicates whether the element has been triggered since the onset of the parent event. The element gets triggered each time when the current webpage is fully loaded.Boolean
Page SizeReturns the size of the current web page.clSize

Alpha MaskingDefines whether the visual content rendered by this element will be used as an opacity mask which is applied onto the given event surface. The active opacity mask allows one to expose pixels of the parent event surface through a solid background of the given event. If the value is true, the darker pixels of the content will make more transparent holes on the entire event surface.Boolean
AntiAliasingIf true, the rendered content will be anti-aliased for smoother visual appearance. If false, rendering will be authentic to its source, e.g. a bitmap. Boolean
PositionDefines the position of the element viewport on the screen. The position can be set in any of three coordinate systems: a) pixels, b) polar, c) central. clPoint
SizeDefines the size of the element viewport on the screen. The size can be set in any of three coordinate systems: a) pixels, b) visual degrees, c) 'relative-to-screen' size. clSize
Z OrderIndicates the current depth order of the element viewport on the surface of the parent event. The greatest number corresponds to the top position. The order can be changed by moving the element up and down in the element list.Int32
Pivot PointDefines the pivot point (coordinate and the rotation centers) within the element viewport. stAlignment or Int32
VisibleDefines whether the element is currently visible on the event surface. The property is convenient for switching visual content on and off. Boolean
RotationDefines the rotation angle (in degrees) of element viewport relative to the its pivot point. Double in the range 0..360
Transparent ColorThe color of the original pixels of rendered content that will be set as transparent. stColor
Transparency ToleranceTolerance ratio for choosing colors that become transparent. Zero means that effect is not applied, 1 denotes that all colors will become trasparent. Int32, range (0..100)
Color MaskProduces a multiplicative combination of the original pixels and the selected mask color (except the alpha channel). The effect emulates a look through a colored glass. White or transparent mask color doesn't change the original pixels. stColor
OpacityOpacity of the rendered content. Int32, range (0..100)
ContrastContrast of the rendered content. Int32, range (-100..100)
BrightnessDefines the brighness of the rendered content. Int32, range (-100..100)
SaturationSaturation of the rendered content. Double
PixelationDefines the pixel scale of the rendering. Int32, range (0..100)
BlurringThe radius used in the gaussian blur of rendered content, as a pixel-based factor. The default is 0 which means no blurring. Int32
Reset JitterSet to true at runtime to reset the current positional jitter.Boolean, set true for action
Current JitterJitter range, in pixels (non inclusive)..clSize
Jitter RangeJitter range, centered at the original position of the element.. clSize

Is EnabledIf set to false the element is completely omitted when the experiment is run.Boolean
TitleTitle of the element.String

Web Browser element provides a live web browser to participants. The browser works in a borderless viewport that can be placed anywhere on the parent event's surface. Apart of providing a regular web experience to participants, the browser element allows a full control of the browsing process by a researcher. The control may include a forced navigation, reading HTLM sources, settings regions of interests, custom overlays and even running custom JScripts on pre-existing pages. When coupled with Web Heatmap and Web Scanpath elements, the browser element allows to record eye-tracking data for entire web page, rather than for a currrently visible part.
