Frameworks Enabling Ubiquitous Mixed Reality Applications Across Dynamically Adaptable Device Configurations

Sandro Weber, Linda Rudolph, Sven Liedtke, Christian Eichhorn, Daniel Dyrda, David A. Plecher, Gudrun Klinker
2022 Frontiers in Virtual Reality  
If Mixed Reality applications are supposed to become truly ubiquitous, they face the challenge of an ever evolving set of hardware and software systems - each with their own standards and APIs–that need  ...  Instead we need frameworks that are modular and flexible enough to be adapted to the needs of the application at hand and are able to incorporate a wide range of setups for devices, services, etc.  ...  There are also research-based efforts which mostly produce new concepts but (in the domain of MR) rarely maintained and reusable code: There is the approach of adding a blockchain as a tool to reach serverless  ...

A Sociotechnical View of Algorithmic Fairness [article]

Mateusz Dolata and Stefan Feuerriegel and Gerhard Schwabe
2021 arXiv   pre-print
However, based on a state-of-the-art literature review, we argue that fairness is an inherently social concept and that technologies for algorithmic fairness should therefore be approached through a sociotechnical  ...  We call for and undertake a holistic approach to AF. A sociotechnical perspective on algorithmic fairness can yield holistic solutions to systemic biases and discrimination.  ...  On Fairness and Calibration.  ...

Health State Estimation [article]

Nitish Nag
2020 arXiv   pre-print
This dissertation presents an approach to build a personal model and dynamically estimate the health state of an individual by fusing multi-modal data and domain knowledge.  ...  Connecting these four elements via graph network blocks forms the backbone by which we instantiate a digital twin of an individual.  ...  Some methods for addressing security are being taken, such as blockchains used for storing and sharing information that is secure because of its transparency.  ...

Fan Zhang
2020
He is a member of IC3 (Initiative of Cryptocurrencies and Contract) and an IBM Ph.D. Fellow for 2018-2020.  ...  A key reason is a disconnection from the real world: There is currently no secure, decentralized way to faithfully convey real-world states to blockchains.  ...  An old committee of size n with a (t, n)-sharing of a secret s can transition during a handoff to a possibly disjoint new committee of size n with a new (t, n)-sharing of s.  ...
