Virtual Reality (VR) is an artificial environment that is created with software and presented to the user in such a way that want the user suspends believe and accepts it as a real environment. On a computer, virtual reality is primarily experienced through two of the five senses: sight and sound. The user can through virtual reality interactive with the computer, the activity is actually manipulating keys or the mouse so that you can control or adjust in the image move in some direction. Virtual Reality experience is like 3D images that appear from the perspective of the user, the ability is to track a user’s motions, particula­rly his/her head and eyes movements, and correspondingly adjust the images on the user’s display to reflect the change in perspective. There are few types of Virtual Reality such as Virtual Reality Games, Virtual Reality Gear and so-on.

Virtual Reality Gaming is where a person can experience being in a 3D environment and interact with that environment during a game. There are small sensor censors which are attached to a data glove, suit or even the body and record movements made by that person in a 3D space. The controller is not only a commercially available device with some tracking capabilities; it’s also affordable and appeals to people who don’t normally play video games.

Those movements will be interpreted by a computer  and give a variety of responses within that space. For example, you wear a data glove which has sensors attached to it. If you wear it in a driving game, the sensors will follow your hands moves whenever you turn to anywhere just like turn the steering wheel, when turning the steering wheel in a particular direction. These movements will transfer back to a computer which then analyses the data and to transform your actions into the appropriate responses on the screen. The video game industry in particular has contributed advancements in graphics and sound capabilities that engineers can incorporate into virtual reality systems’ designs to improve the interaction.

So now I talk about one of the virtual reality gaming’s product, which is Oculus Rift. Oculus is producing (SDK) to assist developers integrate oculus rift with their games, the Rift uses various techniques to improve ‘immersion’ and one of the elementary methods is via ‘head tracking’. When you have a device that calculates the movement of your head and imitates that to produce an output, you deal with artificial intelligence at a different level. The features of the head-tracking device is that you no longer need to use electronic device such as ‘mouse’ or ‘joystick’ manually in response to the movement of the head.

Topic 2: Body and Identity, The Development of Telepresence and Telerobotics

For this topic I’m going to explore about Telepresence and Telerobotics. First of all, what is Telepresence? Telepresence refers to a set of technologies which allow a person to feel as if they were present, to give the appearance of being present. It is giving you a visual effect in the technology tool, it must be generate by technology tool such as computer or mobile device. Telepresence requires that the users’ senses be provided with such stimuli as to give the feeling of being in that other location. Additionally, users may be given the ability such as the user’s position, face expression, gesture, movements, actions, voice and so-on to improve the thing you trying to express to affect the remote location.

Telepresence videoconferencing is a two-way, high definition communication and collaboration tool that provides an experience to users like having a conversation in the same room. Telepresence videoconferencing technically apply in business collaboration, it allows users to connect two or more locations and offers employees, customers, and business partners a level of flexibility and quality communication that significantly increases business productivity while streamlining work processes. Not only that, if you want to have a long distance meeting with customers or business partners, you may use telepresence videoconferencing. The telepresence technology is a combination of four elements which is high-quality audio and video, simplicity, high-reliability, and environmental excellence.

Telepresence is using technology to get a sense of shared presence or space among geographically separated members of a group. There are two types of spaces which is person space and task space. Person task is sence of co-presence which is facial expression and body language that you could make in telepresence videoconferencing. On the other hand, Task space is co-presence in domain of task being undertaken. The importance of person space are Inability to establish eye contact, use portrait rather than landscape orientation, when using multiple sites use video surrogates and also scale can be important. About task space, usually are using the same video channel to share the copy of documents.

Telerobotics is the area of robotics that is concerned with the control of robots from a distance. It is qutie similar in meaning to the phrase “remote control” but is usually encountered in research, academic and technical environments. Telerobotic also called teleoperation, teleoperation is standard term in use both in research and technical communities and is by the distance they had set in earlier, but most standard term for referring to operation at a distance. In this century, most of medical centre had started to use telerobotics in medical application. However, any decision before making have to done by human first while the robot is responsible for their mechanical implementation. Using teleoperation, most of the surgeries can be performed by using minimally invasive surgical techniques, in which there is only small incision site for instrument entry. As a result, this causes less pain to the patients and there will be less tissue trauma, thus reducing hospitalization time and enhancing recovery. For example, in many operations such as eye surgery, small precise movements are needed. As a result, the telerobotics can minimize the risk of operation, the operation hand movements on the controls are scaled down so that very fine instrument movements can be performed.
