Tutorial: Utilize Show Guidance feature

When you activate Show Guidance option in the Welcome tab of Preferences, if there is an operator in front of the camera that is not performing any operation, the guidance image can be shown.

For example, you can show messages such as "Please show your palm towards that camera" or "Stand on the mark below and raise your hand towards the camera".

 The state of Guidance image will change as mentioned below.

1. No operator detected > Hide Guidance
2. Operator is detected > Show Guidance
3. Operator starts operation > Hide Guidance
4. 10 seconds after the operator stops operation > Show Guidance (Back to state #2)
   
   
   Hint: The interval time of state #4 can be customized. See Set the interval time to display the guidance image again in the Other Customization page.

For more information about customization of guidance image, go to Modify Guidance Image.

Action	Description
Show Guidance	Operator present and No palm operation To estimate if a operator is present or not will be done by detecting if there is a person within the modified distance filter range. When the depth image shown in the aeroTAP 3D camera tab displays a Dark gray rectangle, that means that the operator is present (or detected). The red dot shows the center of gravity for the person. While checking the distance setting, modify the distance according to your usage. No palm operation will be estimated by the time duration after the stop of palm operation.
Hide Guidance	The Guidance will be hidden when palm operation is resumed or operator is no longer detected.

Display style of the Guidance

You can modify the display style and the display position on the Guidance by generating SplashGuide.ini file in the same folder as the bmp.

Style = 0 float, Style = 1 fixed

Trans = 0 - 255 value of transparency (255: opaque)

Example: Content of SplashGuide.ini

x = 100
y = 200
Style =1
Trans=255

Result: Guidance image will be displayed at coordinate (100,200) as a static image. The center position of the guidance image is defined by the x, y values.

Assigning x,y and style can be skipped (omitted).

Default Settings (omitted):

x = horizontal center position

y = vertical center position

style = 0

trans =180

        Coordinates omitted: You can skip assigning coordinates X and Y. When set as the following example, coordinate X = 500 and y= center of Y within the screen will be assigned.

x = 500

style = 0

trans =180
