“…Selain itu juga kemampuan untuk mengontrol gerakan kamera senatural mungkin dengan gerakan manusia akan membuat operator semakin immerse dengan robotnya, seperti ditunjukan oleh Ijsselsteijn [10] dan Drascic [11] dimana operator menggunakan Head mounted display untuk menampilkan informasi visual dan menggerakan kamera. Kamera akan bergerak sesuai dengan gerakan kepala operatornya.…”

AbstrakPada pengendalian robot jarak jauh, dibutuhkan informasi mengenai sekitar dari robot. Informasi ini membuat operator dapat mengendalikan robotnya dengan lebih baik. Informasi visual adalah informasi yang paling banyak digunakan oleh sistem pengoperasian robot jarak jauh. Informasi visual yang digunakan sebagian besar masih menggunakan informasi dua dimensi. Robot menggunakan sebuah kamera dan operator melihat informasi dari sebuah layar monitor. Hal ini memiliki kekurangan antara lain operator tidak mendapatkan efek kedalaman sehingga operator memiliki kesulitn untuk mengira jarak antara robot dan objek didepannya. Kekurangan ini dapat diselesaikan dengan menggunakan sistem visual tiga dimensi. Namun sistem ini membutuhkan kamera stereo yang tidak murah. Penelitian ini meneliti sebuah sistem yang mengunakan dua buah webcam yang terhubung dengan sebuah komputer, dan operator dapat merasakan sensasi 3 dimensi dengan menggunakan sebuah Virtual reality headset Kamera-kamera ini diletakan pada dua motor steper sehingga digerakan keatas-kebawah serta samping kiri dan kanan. Kemampuan gerak ini membuat operator mendapat informasi mengenai keadaan sekeliling dari robot. Motor-motor ini dikendalikan dari headset sehingga memudahkan operator. Sistem ini diharapkan dapat digunakan pada robot yang dikendalikan jarak jauh sehingga operator dapat mengoperasikan robot lebih baik lagi. Kata kunci: Teleoperation, webcam, tiga dimensi, headset AbstractTo control robot remotely, information about the surrounding of the robot is needed. With this information the operator can control the robot better. Visual information is information that is most widely used by the system to control robot remotely. The two-dimensional visual information is used mostly widely, which the robot using a regular camera and the operator view information on a monitor screen. This system has its drawbacks, for example, the operators do not get the depth effect, it makes the operator has difficulty to measure the distance between the robot and the object in front of the robot. This deficiency can be solved by using a three-dimensional visual system. However, this system requires a stereo camera is not cheap. This study investigated the use of two webcams are used on the computer. The system consists of two cameras webcam connected to a computer, and the operator can feel the sensation of three dimensions by using a virtual reality headset. These cameras are placed in two stepper motors which can move into two directions. This motion capabilities can make the operator gets information about the surroundings of the robot. These motors are controlled from the headset making it easier to control the motors. The system is expected to be used on a robot which controlled remotely so that the operator can operate the robot more agile.

“…Setting aside for a moment the issues regarding definitions and terminology surrounding immersion, an objective measure for the evaluation of immersion in VR systems must deal in more tangible and explicit aspects of such systems. The influence that the actual technology used in the level of immersion that may be achieved is well documented through studies that measure the effects of screen size on immersion and the ensuing user attitudes and intents to use (Hou, Nam, Peng, & Lee, 2012), (Biocca, Daugherty, Chae, & Li, 2001) and similar studies on the technical aspects of systems such as depth perception in three dimensional viewing experiences and their influence on immersion (Ijsselsteijn, Ridder, Bouwhuis, & Freeman, 1997). While previous studies exist that propose objective measures for the measurement of immersion, they are based on the measurement of variables such as screen size, resolution, control methods, and latency (Cairns, Berthouze, Dopharee, & Jennet, 2006), or cognitive factors such as imagination, suspension of disbelief, interactivity, sensory completeness, fatigue, disorientation (Psotka & Davison, 1993) -all of which are valid constructs with which immersion has been measured, they are elements of VR system design developed and tailored to post facto immersion and presence studies without the theoretical basis of a theory as to why such elements are effective in immersion.…”

The rapid development of information and communication technologies has opened a whole new realm of applications for these technologies. One such application is the development of virtual reality, which aspires to immerse the user within the system such that they feel more "present" within the portrayed virtual plane of existence than within their true reality. Many studies have developed a variety of approaches and methods on measuring immersion and presence in these systems, yet few have addressed the underlying technology for what it really is -namely communication technologyand evaluated the technology's potential for immersion and presence before exposing the user to the virtual experience. Part of the issue lies in the difficulty in quantifying arguably subjective experiences such as immersion and presence. This study examines the existing literature on the definition and evaluation of immersion, presence, and virtual reality technologies, and aims to provide a theoretical framework through which virtual reality technology may be evaluated based on the human biological apparatus it appeals to. The framework is constructed on a modified version of the Media Naturalness Theory, which was selected as a basis due to the evolutionary support it provides in explaining our communication preferences. The framework may then be utilized to analyze prospective technologies for their potential to provide immersive experiences and incite presence in the users before any exposure or use has taken place, possibly providing further validity to any findings of post-exposure studies (such as with questionnaires so ubiquitous in the literature of the field). Keywords: virtual reality, technology, immersion, presence, Media Naturalness Theory.

Bu kullanımlardan biri de, kullanıcısını sistemin içinde soyutlayarak onun gerçekten var olduğu gerçekliğe oranla sistem tarafından sunulan sanal alemde daha fazla bulunma hissini sunmaya çalışan sanal gerçeklik olmaktadır. Bu sistemlerdeki soyutlama ve bulunuşluğun ölçülebilmesi ile ilgili çeşitli yaklaşım ve yöntemlerin sunulduğu çalışmalar alanyazında (ve bu çalışma kapsamında gerçekleştirilen alanyazın taramasında) yer almaktadır; ancak mevcut çalışmalarda bu teknolojilerin temelini oluşturan iletişim teknolojileri bakımından incelenmeleri ve kullanıcıya sanal gerçeklik deneyimi sunmadan önce, kullanılan araçların içsel soyutlama ve bulunuş sağlama potansiyellerine ilişkin bir yaklaşıma rastlanmamıştır. Bu konuda yaşanan sorunlardan birinin, öznel olarak görülebilecek soyutlama ve bulunuş hissinin ölçülebilir bir halde nicelendirilebilmesindeki sıkıntılar olduğundan söz etmek olasıdır. Bu çalışma, soyutlama, bulunuşluk ve sanal gerçekliğin tanımları ve değerlendiri...

“…Other than them, icon criteria applied to television developed by SAM created in 1980 were used by Lang, Gieger, Strickwerda & Summer (1993) [26]. Slater, Usoh & Steeds (1994) created SUS (Slater, Usoh, & Steeds) questionnaires, and IJsselsteijn, Ridder, Hamberg, Bouwhuis & Freeman (1998) [27] created SSCQE survey. In addition, Lombard, Reich, Grabe, Bracken & Ditton (2000) [28] divided into high presence and low presence creating the television survey to verify presence experience for watching TV.…”
