Binarisation Recommendation for editing the AMDs:
Work directly on the integrated text: a type should have two sections: Syntax (including XML and binary version) and Semantics (including details for both syntax representation).
Recommendation for the design of the binary representation allowing streaming:
- Check with Systems how MPEG-7 Visual Binary representation is combined in an MPEG ISO file or stream.
Note: MPEG-7 Visual defines AU, the same principle should be used for MPEG-V

Binary representation for Bio-sensed Information AP: change the BodyTemperatureSensorType into a one that extends the TemperatureSensorType.
AP: change the size of ABOType into 4 bits
AP: change the dimY of ElectrographSensor in noOfSamples, change dimX in numberOfChannels
Recommendation: clarify the Electrograph syntax to make the distinction between simple and complex signals (labels). Add a table explaining this. Update the semantics

Binary representation for Bend sensor capability and sensed information Summary:
The proposed binarisation is reducing the data size by a factor 10.
Proposal of binarisation for 16 bio-sensors, Gas and Dust, and Bend.
AP: change numOfSensors in numOfChannels
AP: propose a structure of the Bend sensor that is both spatial and temporarily aligned

Study of encoding and decoding of binary representation Implementation of the encoding and decoding in Java that allows processing of generic types but also specific ones (one bit, variable bit length, …).
Recommendation: accept. Commit it as part of MPEG-V reference software in a Utility directory.

Camera
Camera Sensor Type and Command AP: Use the RigidBodyMotionType type for the CameraCommandsType; add the zooming information.
AP: Add the characteristics of the sensor in the CameraSensorType

Proposed modification for multi interaction point, gaze tracking and wind sensors AP: change personIdx by personID
AP: Removing the Wind Sensor is not a good idea. Put it back.
Hand based Interaction for intuitive manipulation Summary:
The examples of Touch and Hand Interaction are described.
General discussion:
Once again, the issue of splitting between MPEG-V and MPEG-U part 2 was extensively discussed for the case of gestures. The open problem is that the gesture is captured by the sensors and the scene can use it directly or processed by a intelligent software that extract the semantic of the gesture.
The resolutions are:
- design the gestures types without considering the possible splitting.
- do the splitting in a joint meeting based on the consideration of the level of interpretation of the gesture
