Nowadays information technologies are getting more and more into the foreground in our daily lives. The way of managing or controlling of devices and systems is getting more comfortable and user friendly. In following pages new and modern technologies for system control and navigation will be introduced.

Nowadays gestures are very popular way for application or systems control and many people are using it every day. Gesture controls feel natural because they are associated with the way people interact with real objects. Actually, we are using gestures in our mobile devices, computers applications, augmented reality/virtual reality (AR/VR) applications, game consoles, etc. Thanks to their everyday use, gestural interfaces are beginning to move into other areas of technology. It is expected that gestural interaction will be available in almost every device in just a few years’ time. High popularity of gesture navigation forces researchers to improve these technologies. This is an obvious trend since computer performance is no longer the bottleneck of the more natural navigation and control using gestures [1].

Due to the existence of so much information available just one click away, it is not possible for an individual to keep up with all the data they can be interested in. By using technology, information can be selected for the users beforehand. That is why Recommendation Engine is a powerful tool which can make users stop wasting their time searching and scrolling information they do not really care about. Based in their preferences, the system is able to predict what we will be accordant to the user [6].

In the last few years, voice recognition has made considerable leap in speed and quality.

Very interesting technology for device control is the Brain Computer Interface (BCI). BCI represents (simply say) a direct communication pathway between human brain and external device. In this module we will introduce also eye tracking, where measuring eye activity is used to control device.
