Support av Fälttekniker med Google Glass och WebRTC (Swedish)
Abstract [en]

The Internet is dramatically changing the way we communicate, and it is becoming increasingly important for communication services to adapt to context in which they are used.

The goal of this thesis was to research how Google Glass and WebRTC can be used to create a communication system tailored for field service support.

A prototype was created where an expert is able to provide guidance for a field technician who is wearing Google Glass. A live video feed is sent from Glass to the expert from which the expert can select individual images. When a still image is selected it is displayed to the technician through Glass, and the expert is able to provide instructions using real time annotations.

An algorithm that divides the selected image into segments was implemented using WebGL. This made it possible for the expert to highlight objects in the image by clicking on them.

The thesis also investigates different options for accessing the hardware video encoder on Google Glass.

Abstract [sv]

Internet har dramatiskt ändrat hur vi kommunicerar, och det blir allt viktigare för kommunikationssystem att kunna anpassa sig till kontexten som de används i.

Målet med det här examensarbetet var att undersöka hur Google Glass och WebRTC kan användas för att skapa ett kommunikationssystem som är skräddarsytt för support av fälttekniker.

En prototyp skapades som låter en expert ge vägledning åt en fälttekniker som använder Google Glass. En videoström skickas från Glass till experten, och denne kan sedan välja ut enstaka bilder ur videon. När en stillbild väljs så visas den upp på Glass för teknikern, och experten kan sedan ge instruktioner med hjälp av realtidsannoteringar.

En algoritm som delar upp den utvalda bilden i segment implementerades med WebGL. Den gjorde det möjligt för experten att markera objekt i bilden genom att klicka på dem.

Examensarbetet undersöker också olika sätt att få tillgång till hårdvarukodaren för video i Google Glass.
