Hi Roland,
I would like to briefly describe what my students are dealing with and where we still have problems.
My students have designed and built an assembly workstation where various battery housings are to be assembled.
In order to train employees at this assembly workplace, an AR experience was created for the HoloLens.
The playback of the individual work steps (one after the other) is controlled via Thingworx parameters.
These parameters in Thingworx (Industrial Thing - Industrial Connection) are controlled via Kepware by a PLC Siemens C1215C.
Sensors check which battery housings are being delivered or need to be assembled and whether the work steps have been carried out correctly.
We also want to show waypoints for specific work steps.
The housings are delivered to the lefthand side of the worker - here we want to display a waypoint.
The worker then places the finished housing on the right side of the conveyor belt - we also want to display a waypoint there.
No waypoint should be displayed during the other work steps.
I tried the following code on a simple example:
Language selection: By clicking on the button, the language is set to German or English (with the variable lang2)
var lang2 = 'deu';
$scope.onSprachauswahl_Pressed = function() {
lang2 = 'deu';
$scope.app.view['Home'].wdg['3DLabel-lang2']['text'] = lang2;
};
$scope.onSprachauswahl_Unpressed = function() {
lang2 = 'eng';
$scope.app.view['Home'].wdg['3DLabel-lang2']['text'] = lang2;
};
At the beginning, the Wayfinder widget is deactivated via the application parameter "enable_wayfinder" which controls the property "Enabled".
$scope.app.params.enable_wayfinder = false;
If the parameter "Gehaeuse_VS" is "true" controlled via Thingworx, waypoint 2 (Waypointndex = 1) should be displayed and when reached
(Waypoint_arrived) a text is displayed depending on the language selection and a sound file and then a sequence (not entered here) is played.
$scope.$watch("app.params['Gehaeuse_VS']", function() {
if ($scope.app.params.Gehaeuse_VS == 'true') {
$scope.setWidgetProp('wayfinder-1','selectedWaypointIndex',1)
$scope.app.params.enable_wayfinder = true;
$scope.Waypoint_arrived = function() {
if (lang2 == 'deu') {
$scope.app.view['Home'].wdg['3DLabel-Textanzeige']['text'] = "Gehäuse von links einbauen!";
} else {
$scope.app.view['Home'].wdg['3DLabel-Textanzeige']['text'] = "Assembly the Battery housing from the left side!";
}
$scope.app.params.enable_wayfinder = false;
var soundFilePath = "app/resources/Uploaded/Gehaeuse_" + lang2 + ".mp3";
var audio = new Audio(soundFilePath);
$timeout(function() {
audio.play();
}, 500);
}
}
});
In the Preview this works so far, but at the end the Wayfinder widget is not deactivated again but rather remains displayed and active.
However, it works on HoloLens2.
The following step is one without a waypoint, controlled via the parameter “Deckel_VS”, again via Thingworx.
$scope.$watch("app.params['Deckel_VS']", function() {
if ($scope.app.params.Deckel_VS == 'true') {
if (lang2 == 'deu') {
$scope.app.view['Home'].wdg['3DLabel-Textanzeige']['text'] = "Deckelmontage, Aufschrift PIA Automation muß sichtbar sein!";
} else {
$scope.app.view['Home'].wdg['3DLabel-Textanzeige']['text'] = "Install the cover, PIA Automation label must be visible.";
}
var soundFilePath = "app/resources/Uploaded/Deckel_" + lang2 + ".mp3";
var audio = new Audio(soundFilePath);
$timeout(function() {
audio.play();
}, 500);
}
});
In this step, waypoint 1 should be displayed with Waypointindex = 0 and should be deactivated again after arriving waypoint 1
$scope.$watch("app.params['Akkuzelle_VS']", function() {
if ($scope.app.params.Akkuzelle_VS == 'true') {
$scope.setWidgetProp('wayfinder-1','selectedWaypointIndex',0)
$scope.app.params.enable_wayfinder = true;
$scope.Waypoint_arrived = function() {
if (lang2 == 'deu') {
$scope.app.view['Home'].wdg['3DLabel-Textanzeige']['text'] = "Akkuzelle an der richtigen Position platzieren!";
} else {
$scope.app.view['Home'].wdg['3DLabel-Textanzeige']['text'] = "Place the battery cell in the correct position.";
}
$scope.app.params.enable_wayfinder = false;
var soundFilePath = "app/resources/Uploaded/Akkuzelle_" + lang2 + ".mp3";
var audio = new Audio(soundFilePath);
$timeout(function() {
audio.play();
}, 500);
}
}
});
Here again, the wayfinder widget is not deactivated in the preview and rather remains active and the waypoint is displayed, however it works on HoloLens2.
The Preview:
On HoloLens2:
I hope the code above fits our needs.
Thanks for the quick answers.
