3D USER INTERFACESReportAhmed
AbstractThe three dimensional user interface or 3D UIs allows a person to interact with differentenvironments, virtual objects or information using a direct 3D input in virtual or physicalspace. With the advent of modern generation devices such as Nintendo Wii or Holographicvirtual reality interfaces such as Microsoft HoloLens, the 3D UIs are now longer a work offiction, rather they have started to become mainstream. With this kind of intervention, thebiggest problem that 3D UI researchers and interface designers face is how to tackle theusability aspect of 3D interface as the user interfaces have predominantly been made in 2D.As a result, usability aspect is still surprisingly low when it comes to 3D UI basedapplications.1

IntroductionWith the advent of virtual reality based environments combined together with technologiessuch as augmented reality, three dimensional applications and large-screen format displayscreens, a new trend has emerged in the Human Computer Interaction. Although, there aredecades’ worth of experience in applying design principles for traditional UIs, they are stillnot sufficient in 3D spatial context that involves multiple degrees of freedom. The applicationdevelopers, designers and researchers quickly realized that the 3D domain had somefundamental differences between them and that newer methods would be needed to developapplications for the 3D User Interface. This particular area is known as 3D User Interfaces,3DUI or 3D interaction. A typical 3D based interface involves special spatial based input devices such as 3D pointingdevices, gestural input, head-mounted displays or HMDs, stereoscopic projects, hapticfeedback devices and even spatial audio systems. However, with these new technologies,people find it difficult to understand and perform action in 3D spaces[2]. Although, we live ina 3D world, it’s an inherently very different than a 3D world as for performing actions in thereal world there are lot of hints, cue and feedbacks available for which the same cannot berepresented in a computer simulation. As a result, simply adapting a traditional WIMP orWindows Icon Menu Pointers based interface into a 3D will not be an effective solution.Instead, a new design process has to be established that allows successful transformation ofthe traditional interface into a 3D based interface. Background Research3D interaction is defined as “Human Computer Interaction wherein the tasks performed bythe user is directly in a D spatial context” . However, an interactive system that would displaya 3D graphic does not necessarily means a 3D interaction. For instance, a user viewing a 3Dmodel of a building on their computer does not mean a 3d interaction has taken place. Now,these definition may not necessarily classify all of the 3D interaction that takes place,however, we could possibly classify them based on the context wherein the 3D interactiontook place [20].These include:3
