Person Tracking with Depth Cameras - Dave Shinsel Chalk Talk
June 5th
6:30 PM (2 hours)
Axiom Electronics


*** Date Change ***

“Having accurate knowledge of the positions of people around a robot provides rich, objective and quantitative data that can be highly useful for a wide range of tasks, including autonomous person following.” [Leigh, Pineau, Olmedo, and Zhang]

Dave Shinsel suggests this topic for his next ROS chalk talk. His experience as an Intel RealSense manager will provide valuable insights.

He will provide a comparison of current support options including:
   Hardware:  Orbbec Astra, Orbbec Astra Mini, New RealSense DS 435 
   Software:  Orbbec Astra SDK, NuiTrack SDK.
   Camera Type: Person tracking with depth cameras vs. 2D cameras

He has written ROS nodes for each and will discuss the implementation and challenges.

Oregon Comsoc Distinguished Speaker: Physical Layer Millimeter-wave Communications
June 13th
6:00 PM (2.2 hours)
Tektronix Building 38 Atrium


Millimeter wave (mmWave) communications is viewed as the key enabler of 5G cellular networks due to vast spectrum availability that could boost peak rate and capacity. Due to increased propagation loss in mmWave band, transceivers with massive antenna array are required to meet link budget. While massive antenna arrays enable high gain, directionality and user multiplexing, practical realizations face many challenges in radio design and physical layer processing. In this talk, we first review emerging massive array architectures for mmWave communications and compare their performance, power consumption, and cost with comprehensive hardware block model under typical application use cases. We then discuss two important physical layer design aspects in mobile mmWave networks: directional link establishment via initial access and directional link maintenance via mmWave channel tracking. Lastly, we present the state-of-the-art designs of current mmWave standards, discuss their limitation and provide perspectives on innovative approaches for performance boosts and hardware improvements
