Overview
This lesson introduces Interactions. Interactions define how a presenter can present content using Chyron Weather. The types of interactions available, how to select them and their properties, is discussed.
| Prerequisites: Lessons 01, 03, 04, and 05 |
Types of Interactions
The Interactions panel provides access to the Interactions available to use during a Presentation.
Image description: Interactions panel
Five types of Interactions are available (left to right):
- Trigger action
- (screen) Corner Tapp
- Double Tapp
- Touch and hold
- Touch and move
- Interaction options
Associated with each interaction is a separate actions possible.

| Interactions Panel Actions | ||
|
1 |
Skip to next segment |
Skips to the next segment immediately |
|
2 |
Finish segment repetition |
Skips to the next segment once animation finished |
|
3 |
Pause/resume playback |
Animations can set to ignore the pause |
|
4 |
Zoom to location |
Zooms to the touch position |
|
5 |

Resets view |
|
6 |

Adds an object at the touch position |
|
7 |
Pan |
Moves the camera |
|
8 |
Scrub time Line |
Scrub forward/backward |
|
9 |
Add and drag object |
Adds a moveable object at the touch position |
|
10 |
Add and draw object |
Adds a drawable object at the touch position |
Image description: Ignore action
By default, the Trigger action is set to ‘Ignore’. Without defining an action, the Playlist cannot be triggered.
If you are unable to play your presentation, review the Trigger action setting.
Interaction options properties
Some actions have properties. These are set via the properties button.
Lesson 6.6 illustrates the button:

The Properties available are relative to the action.
Following is a list of actions with editable properties but first a brief description of each property.
Table description: Properties of interactions
|
Properties of Interactions |
|
|
Lead–in [s] |
Defines how long the action will take to fade in. Measured using seconds.
|
|
Lead–out [s] |
Defines how long the action will take to fade out. Measured using seconds. |
|
Target Layer |
Defines which layer will be the target of the action. Normally set to the ‘Topmost geo layer’. |
|
Focus zoom factor
|
Defines the zoom factor of the camera |
|
Target Collection |
Defines which Content Collection will be the target of the action |
|
Scrub Sensitivity |
Defines the scrub sensitivity |
Zoom to location
- Lead-in: speed of the zooming
- Target layer: which geo layer should be zoomed (if available)
- In most cases: “Topmost geo layer”
- Focus zoom factor: defines the zoom steps
Image description: Zoom to location action properties
For touch and move interactions the zoom level is defined by how far the finger is dragged from the touch point. Therefore, lead-in and focus zoom factor cannot be set.

Reset camera
Lean-in defines the time frame for zooming out to the original map cutout.
Image description: Reset camera action properties
Add object / Add and drag object / Add and draw object
- Lead-in: Define how long the object will take to fade in
- Lead-out: Define how long the object should fade out
- When typing “Infinity” it will fade out with the target collection
- Target collection: in which content collection the object is put
- Depending on layering/hierarchy and fading out
- Choose object to add/drag/draw (double click on subscene)
- Add and draw requires a vertex object (customObj)
Image description: Add object action properties
Pan
Select the target layer.
Image description: Pan action properties
Scrub timeline
Scrub sensitivity defines, how fast the scrubbing animation will be.

| Note: There are no editable properties for the Ignore, Skip to next segment, Finish segment repetition and Pause/resume playback actions. |
Touch settings
Touch settings are accessed via Application Menu/Settings/Touch Settings.
Image description: Default Touch Settings values
Table description: Touch screen settings
|
Touch Setting |
Description |
|
Dead Zone |
Defines dead zone around the touch area. Measured in pixels. Values range from 0 to 40. Default is 20. |
|
Double Touch Area |
Defines area within which a second touch is detectable. Measured in pixels. Values range from 1 to 81. Default is 21. |
|
Corner Size |
Defines the size of the corner touch area. Measured in pixels. Values range from 10 to 300. Default is 110. |
|
Drag Slippage |
Defines the slippage of an object when dragged. Values range from 0 to 3. Default is 1. |
|
Camera Inertia |
Defines the inertia of the camera when panning. Values range from 0 to 5. Default is 3. |
|
Hold Duration |
Defines the timeout between interactions. Measured in milliseconds. Values range from 0 to 2000. Default is 1000. |
|
Interaction Time–out |
Defines the timeout between interactions. Measured in milliseconds. Values range from 0 to 2000. Default is 1000. |

Question 1: Which interaction allows you to insert a weather symbol? A. All interactions which include actions with specific properties B. Just double-tap C. All interactions which include connectable actions to a target collection
Question 2: Which interaction can change the current reference time of an object during presentation? A. Touch and Move B. All interactions C. No interaction
Question 3: What happens if no interaction is set to get to the next segment? A. The presentation will always stay at the current segment B. The presentation will always go to the next segment when the duration of the current segment is passed C.
