+Data capture context
+====================
+
+The context handles incoming eye tracker data before to pass them to a processing pipeline.
+
+## live_streaming_context.json
+
+For this use case we need to connect to a Tobii Pro Glasses 2 device: **ArGaze** provides a [ready-made context](../../user_guide/eye_tracking_context/context_modules/tobii_pro_glasses_2.md) class to capture data from this device.
+
+While *address*, *project*, *participant* and *configuration* entries are specific to the [TobiiProGlasses2.LiveStream](../../argaze.md/#argaze.utils.contexts.TobiiProGlasses2.LiveStream) class, *name*, *pipeline* and *observers* entries are part of the parent [ArContext](../../argaze.md/#argaze.ArFeatures.ArContext) class.
+
+```json
+{
+	"argaze.utils.contexts.TobiiProGlasses2.LiveStream": {
+		"name": "Tobii Pro Glasses 2 live stream",
+		"address": "10.34.0.17",
+		"project": "HAIKU-XP",
+		"participant": "Pilot-A",
+		"configuration": {
+			"sys_ec_preset": "Indoor",
+			"sys_sc_width": 1920,
+			"sys_sc_height": 1080,
+			"sys_sc_fps": 25,
+			"sys_sc_preset": "Auto",
+			"sys_et_freq": 50,
+			"sys_mems_freq": 100
+		},
+		"pipeline": "live_processing_pipeline.json",
+		"observers": {
+			"observers.IvyBus": {
+				"name": "argaze_haiku",
+				"bus": "10.34.127.255:2023"
+			}
+		}
+	}
+}
+```
+
+The [live_processing_pipeline.json](pipeline.md) file mentioned above is described in the next chapter.
+
+The *IvyBus* observer object is defined into the [observers.py](observers.md) file that is described in a next chapter.
