In the current field of cooperation in Mixed Reality there is, at the timeof writing, a clear lack of research regarding the cooperation between animmersed Virtual Reality user and a non-immersed audience. Therefore, theimpact of adding audience-controlled cameras to the two parties’ cooperationwas investigated. This was done through a user study where the participantswere cooperating as a Virtual Reality user and an audience to find hiddenobjects. The study was conducted with two prototypes. In the first prototype,the audience was only able to see a mirrored view of the immersed user. Inthe second, independent smartphone-controlled cameras were added to thedisposal of the audience. The results of the user study indicate that the secondprototype was overall less practical than the first in effectiveness, efficiencyand satisfaction. However, in certain scenarios where the number of objectswithin a scene made verbal communication inefficient, the second prototypeprevailed, indicating its potential in more visually complex scenes. / I det nuvarande fältet av samarbete inom Mixed Reality finns det i skrivande stund en tydlig avsaknad av forskning angående samarbete mellan en fördjupad Virtual Reality-användare och en icke-fördjupad publik. Därför undersöktes effekten av att inkludera publikkontrollerade kameror i de två parternas samarbete. Det gjordes genom att utföra en användarstudie där de två parterna samarbetade som Virtual Reality-användare och publik för att hitta gömda objekt. Användarstudien genomfördes med två prototyper. I den första prototypen kunde publiken endast se en speglad bild av den fördjupade användarens synfält. Detta kompletterades av enskilda smartphonekontrollerade kameror avsedda för publiken i den andra prototypen. Användarstudiens resultat indikerar att den andra prototypen generellt presterade sämre än den första inom områdena effektivitet, verkan och tillfredsställelse. Dock, i vissa scenario när antalet objekt i en scen gjorde verbal kommunikation ineffektiv visade sig den andra prototypen vara bättre, vilket indikerar dess potential för mer visuellt komplexa scener.

The main interfaces for interaction with computers today are; keyboard, mouse and remote control. In order to interact with the presentation software Power Point, the presenter has to focus either on the computer or the buttons on the remote control. By doing this, the presenter often loses the contact with his audience and his or her flow of speech gets interrupted. This project has researched the possibility of using gestures for interaction with Power Point, by using an appliance that detects gestures. The purpose was that the interaction should be possible to realise by software, which we have done an introductory design of. We have focused on assisting presenters when they use Power Point and other applications when delivering presentation. To collect data and get an understanding of presenters, presentations and gestures we have observed presenters in action, done workshops together with future users and tested some gestures in real life. These are methods inspired from approaches such as ethnographic fieldwork and participatory design. During the whole project we have used video recording to collect and save data. To create an understanding and clear picture of what the future software should include UML-diagrams were used. We have separated gestures in two categories; natural and designed. The natural gestures occur naturally during speech and social interaction, while the designed gestures are gestures that you learn to use and express, often to perform a task. We discovered that it was the designed gestures that are best suited for gestural interaction with computer. Since the designed gestures are close to the natural way of gesturing we see them as easier to learn, remember and also more comfortable to use. We think the designed gestures have the potential to become second nature, therefore they are good to use for interaction with computers. Our research work led us to realise a need for an on/off function, to distinguish the designed gestures from the natural ones. By using a gestural interface during a presentation, the presenters can keep the focus on the audience and the message they want to convey. When gestural interfaces become reality they will introduce a paradigm shift in the way that people interact with computers and information. / Anette Eriksson 0457-12196 Caroline Svensson 0410-24148
