As part of the lecture “Software Development for Cloud Computing” we were looking for a solution, how a user can get basic assistance within our existing virtual reality game AIRA. The primary objective was a maximum of user-friendliness, while avoiding an interruption of the immersive gaming experience. It is also important to keep in mind, that the user is on its own and any kind of support from outside is usually not possible.
Moreover, considering that within virtual reality applications generally no conventional input devices will be available and therefore a keyboard is not an option. If we still following up this idea, many people may think next of an on-screen keyboard, as they know it from their smart TV at home, which might be operated by a game controller. Although such an approach would be contrary to a high ease of use and majority of implementations are quite crippled as well as hard to use.
So, what would be obvious and take all previous considerations into account? Simply think of something that each of us is carrying along at any time – the own unique voice. According to this we decided to implement a personal voice assistant into our game. In the following, it can be seen that the individuality of each human voice leads into a lot of difficulties we have to take care of.
In the following, it will be explained in detail how we implemented a personal voice assistant using multiple Watson services, which are part of the IBM Bluemix cloud platform. Especially fundamental problems we run into will be discussed and then possible approaches will be pointed out.
Howdy, Geeks! Ever frustrated by public transportation around Stuttgart?
Managed to get up early just to find out your train to university or work is delayed… again?
Yeah, we all know that! We wondered if we could get around this issue by connecting our alarm clock to some algorithms. So we would never ever have to get up too early again.
Well, okay, we’re not quite there yet. But we started with getting some data and did some hardly trustworthy hypothesis of prediction on it. In the end it’s up to you if you gonna believe it or not.
To give you a short overview, here are the components that are involved in the process. You will find the components described in more details below.
A view parts in short:
1. crawler and database – get and store departure information
2. visualization – visualizes the delays on a map
3. statistical analysis – some statistical analysis on the delays over a week
4. continuous delivery – keep the production system up to date with the code
New data is created every second. Just on Google the humans preform 40,000 search queries every second. By 2020 Forbes estimate 1.7 megabytes of new information will be created every second for every human on our planet.
However, it is about collecting and exchanging data, which then can be used in many different ways. Equipment fault monitoring, predictive maintenance, or real-time diagnostics are only a few of the possible scenarios. Dealing with all this information, creates certain challenges for stream processing of huge amounts of data is among them.
Improvement of technology and development of big scaling systems like IBM Bluemix it is now not only possible process business or IoT data, it is also interesting to analyze complex and large data like sport studies. That’s the main idea of my application – collect data from a 24-hour swimming event to use real time processed metrics to control event and athletes flow.
In this article explains how to integrate and use the IBM tools for stream processing. We explore IBM Message Hub (for collecting streams), the IBM Streaming Analytics service (for processing events) and IBM Node.JS Service (for visualization data).
