The Internet of Things (IoT) identifies the network of interconnected systems, machines, and things that communicate and collaborate without human intervention. Techno-economic forecasts indicate that wireless IoT will become massive in the coming years, connecting tens of billions of devices. The IoT has significantly different requirements and traffic characteristics from both, traditional human-to-machine (H2M) services (download, web browsing, video streaming) and human-to-human (H2H) communication, where large data volumes are sent, high data rates are required, and infrequent access requests to the network are performed. In contrast, IoT communication is oftentimes based on the intermittent transmission/reception of small data portions and presents strict latency, reliability, and energy efficiency requirements. Thus, adequate traffic models are required to efficiently manage IoT traffic. Recent standardization efforts led to the development of the narrowband Internet of Things (NB-IoT), the low-power wide-area implementation in cellular base stations. NB-IoT has positioned itself as the major player in the IoT sector due to its greater transmission range and longer battery lifetime with respect to other IoT technologies. Distributed ledger technologies (DLTs) and machine learning techniques nicely complement NB-IoT. DLTs provide secure, reliable, and transparent data transmission, whereas machine learning can be used to optimize performance.

In summary, this workshop includes:

  • Use cases and performance requirements for IoT applications,
  • Theoretical aspects and fundamentals of wireless communications for the IoT,
  • Basics of machine learning and data analytics for the IoT,
  • The role of DLTs in NB-IoT applications,
  • Details of NB-IoT access protocols,
  • Joint project discussion and planning,
  • Hands-on sessions to program the NB-IoT devices and setup the applications.

The participants will learn:

  • The theoretical basis and design principles of wireless communication protocols and IoT architectures,
  • How to program and implement an IoT application with real NB-IoT elements,
  • How to use machine learning and data analytics to maximize the efficiency of IoT applications,
  • How to implement secure and transparent NB-IoT applications with DLTs.

To get the most out of the workshop, prospective students are encouraged to have basic knowledge on wireless communications and programming languages.

Maximum number of participants to be enrolled to the workshop: 32 (full)

As it matures, virtual, augmented, and mixed reality technology (VR) has increasing potential to enable fundamental and transformative advances in a broad range of societally beneficial areas. Sometimes called “the ultimate empathy machine” for its ability to enable compelling first-person experiences, VR is already being actively used many fields, such as: journalism (to bring stories to life), museums (to promote active engagement with cultural and historical content), medicine (e.g. surgical planning, pain management, physical rehabilitation, and more), psychotherapy, architectural and interior design, K-12 education, job training (including implicit bias mitigation), and much more. The global virtual reality market was valued at US $3.13 billion in 2019, primarily driven by the video game industry, but continued rapid growth is expected as the market diversifies. Nonetheless, VR is still an emerging medium, and the creation of compelling and useful applications requires knowledge and skills that are fundamentally different from traditional computing.

This workshop will provide an overview of the theoretical foundations, hardware/software technologies, and interaction techniques necessary to begin creating optimally effective virtual reality experiences. Structured as a mixture of theory and practice, the workshop will also provide students with the opportunity to gain practical experience by implementing 3D user interfaces and developing a prototype VR application motivated by a social good problem.

Major learning objectives include:

  • Understanding virtual reality technologies, including displays, motion tracking, and input devices, and software frameworks such as the Unity game engine
  • Gaining familiarity with both current and future applications of virtual reality, especially those that address societal challenges and contribute to social good
  • Learning about the design and implementation of 3D interaction techniques, including navigation, selection, manipulation, and system control
  • Thinking critically about what makes a virtual reality experience effective and compelling (and conversely, what doesn’t)
  • Gaining practical experience in developing a virtual reality application that applies 3D user interface best practices

In this workshop, we will be using the Unity game engine and C# programming language. Prior experience with these specific tools is not expected. However, students should have solid programming skills in at least one modern programming language (e.g., Java, C++, Python, etc.) and be comfortable with consulting documentation to look up unfamiliar syntax. Basic knowledge of computer graphics is also beneficial, but not required.

Maximum number of participants to be enrolled to the workshop: TBD (few seats left)
