The Rift is a virtual reality head-mounted display developed by Oculus VR. It was initially proposed in a Kick starter campaign, during which Oculus VR.
The simulation aspect of the Oculus Rift can be put to use as a tool for training. It's one of the more obvious non-gaming applications for the device, mostly because non-VR simulations already exist in many fields, but the quality of simulation is what's important here.
"Improving the VR experience, from the authors to the users"
Creating an immersive virtual reality application is a big challenge: choosing (or creating) the right hardware, choosing (or creating) the right software, and finally crafting the user experience. The hardware is increasingly powerful and accessible, but we don't know how to make the best of it. This is in part because designing a VR experience is a complex software task, and is also due to our limited understanding of the main component of the system: the user.
In this talk we will focus the current trends in system design, on the goals and design of MiddleVR, a generic VR plugin aimed at simplifying the creation of VR applications and we will discuss how our understanding of human perception can be used to improve the VR experience.

https://github.com/chrisjz/sm64vr
This tutorial was presented at the Sydney Virtual Reality meetup in June 2014.
These slides use ideas from my class to develop a business model for Oculus Rift’s headset. This headset creates the perception among users that they are in a different reality as they play video games. It has much higher resolution and faster response time than do previous headsets. Although Oculus hopes to develop its own console, these slides recommend that Oculus partner with a console maker such as Sony, Microsoft, or Nintendo in order to reduce development cost and gain access to existing users and game software. Hopefully it can receive a portion of hardware and game software revenues as its headset enables console makers to increase their market share and charge more for game software.

Virtual Reality: Learn to Maximize Present and Future Creative Possibilities!Stephan Tanguay
2014 is the year that virtual reality will go from a bad memory from the 90s to the beginning of a new way to experience content. Already the Oculus Rift has started to transform several industries with its ability to transport you to a completely interactive virtual space. As a designer and/or developer, this transformation will change the way you look at your work.
The first time you build something on the screen and then project yourself into your own creation, you quickly feel a sense of wonder and excitement from experiencing content in a way you never expected. You will also realize that many things that work well with a typical mouse, keyboard and computer screen work considerably different in the virtual world. Sharing these experiences with Stephan will help you to understand how to leverage what works in virtual reality, future possibilities and what to avoid so your virtual experiences will be effective at immersing users in your virtual creations.

Write retrogames in the web and add something more with AzureMarco Parenzan
Mi piacciono i retrogames, sin da quando ho iniziato a usare i computer con il mio amato Commodore 64 negli anni ottanta. Così nel mio (poco) tempo libero cerco di reimplementare, non come sviluppatore professionista, i giochi più semplici e coinvolgenti con cui ho giocato, portandoli sul web con JavaScript e Phaser.io. Quindi voglio condividere la mia esperienza.
Poi, dato che lavoro con Azure e i giochi diventano delle Web App, cerco di evolvere i giochi aggiungendo alcune nuove e moderne funzionalità, così per sperimentare un po' i vari servizi di Azure, soprattutto quelli che normalmente uso meno.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.
Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
