Transcript of Mixed Augmented and Virtual Reality Interactive Presentation

PowerPoint Presentation• What is MAV - mixed, augmented and virtual reality.
• Brief history of virtual and augmented reality. • Benefits of mixed reality in education. • Some examples of where MAV is being used in
CQUniversity. • Future directions for MAV in CQUniversity. • Some easy ways to implement MAV in the
classroom. • Hands on with some virtual and augmented
MAV - mixed, augmented and virtual reality
• Augmented Reality - direct or indirect view of a physical, real-world environment whose elements are augmented (or supplemented) by computer-generated sensory input such as sound, video, graphics or GPS data.
• Virtual Reality - immersive multimedia or computer- simulated reality, replicates an environment that simulates a physical presence in places in the real world or an imagined world, allowing the user to interact in that world.
• Mixed Reality - is the merging of real and virtual worlds to produce new environments and visualizations where physical and digital objects co-exist and interact in real time.

• 360 Video – immersive video recordings of a real-world scene, where the view in every direction is recorded at the same time.
• During playback the viewer has control of the viewing direction and can also be used with virtual reality devices; e.g. Google Cardboard.

• Although considered an “emerging technology” the use of virtual and augmented reality can be traced back as far as 1838.

• 1838 – Stereoscopic photos & viewers • In 1838 Charles Wheatstone’s research demonstrated that the brain processes the
different two-dimensional images from each eye into a single object of three dimensions. Viewing two side by side stereoscopic images or photos through a stereoscope gave the user a sense of depth and immersion.
• The later development of the popular View-Master stereoscope (patented 1939), was used for “virtual tourism”.

1838 : The stereoscope (Charles Wheatstone)
• The design principles of the Stereoscope is used today for the popular Google Cardboard and low budget VR head mounted displays for mobile phones.

Early stereoscopic photo
1950s – Morton Heilig’s Sensorama • In the mid 1950s cinematographer Morton Heilig developed the Sensorama (patented
1962) which was an arcade-style theatre cabinet that would stimulate all the senses, not just sight and sound. It featured stereo speakers, a stereoscopic 3D display, fans, smell generators and a vibrating chair.
• The Sensorama was intended to fully immerse the individual in the film. He also created six short films for his invention all of which he shot, produced and edited himself.
• The Sensorama films were titled, Motorcycle, Belly Dancer, Dune Buggy, helicopter, A date with Sabina and I’m a coca cola bottle!

1950s – Morton Heilig’s Sensorama
1960 – The first VR Head Mounted Display • Morton Heilig’s next invention was the Telesphere
Mask (patented 1960) and was the first example of a head-mounted display (HMD), albeit for the non-interactive film medium without any motion tracking. The headset provided stereoscopic 3D and wide vision with stereo sound.

1961 Headsight – First motion tracking HMD • In 1961, the Headsight was developed the first precursor to the
HMD as we know it today – the Headsight. It incorporated a video screen for each eye and a magnetic motion tracking system, which was linked to a closed circuit camera.
• The Headsight was not actually developed for virtual reality applications (the term didn’t exist then), but to allow for immersive remote viewing of dangerous situations by the military. Head movements would move a remote camera, allowing the user to naturally look around the environment.
• Headsight was the first step in the evolution of the VR head mounted display but it lacked the integration of computer and image generation.

1965 – The Ultimate display by Ivan Sutherland Ivan Sutherland described the “Ultimate Display” concept that could simulate reality to the point where one could not tell the difference from actual reality. His concept included:
• A virtual world viewed through a HMD and appeared realistic through augmented 3D sound and tactile feedback.
• Computer hardware to create the virtual word and maintain it in real time. • The ability for users to interact with objects in the virtual world in a realistic way
“The ultimate display would, of course, be a room within which the computer can control the existence of matter. A chair displayed in such a room would be good enough to sit in. Handcuffs displayed in such a room would be confining, and a bullet displayed in such a room would be fatal. With appropriate programming such a display could literally be the Wonderland into which Alice walked.” – Ivan Sutherland
This paper would become a core blueprint for the concepts that encompass virtual reality today.

1968 – Sword of Damocles • In 1968 Ivan Sutherland and his student Bob
Sproull created the first VR / AR head mounted display (Sword of Damocles) that was connected to a computer and not a camera.
• It was a large and scary looking contraption that was too heavy for any user to comfortably wear and was suspended from the ceiling (hence its name).
• The user would also need to be strapped into the device. The computer generated graphics were very primitive wireframe rooms and objects.

1987 – Virtual reality the name was born
• Even after all of this development in virtual reality, there still wasn’t an all- encompassing term to describe the field. This all changed in 1987 when Jaron Lanier, founder of the visual programming lab (VPL), coined (or according to some, popularised) the term “virtual reality”. The research area now had a name.
• Through his company VPL Research, Jaron developed a range of virtual reality gear including the Dataglove (along with Tom Zimmerman) and the EyePhone head mounted display.
• They were the first company to sell Virtual Reality goggles (EyePhone 1 $9400; EyePhone HRX $49,000) and gloves ($9000). A major development in the area of virtual reality haptics.

• Virtual and augmented reality are often associated with gaming.
• VR, AR and MVR offer many opportunities in education.

Both virtual and augmented reality can support traditional educational methods through: • Offering an active rather than passive experience. • Delivering an immersive experience without distractions. • Increasing students' engagement through engaging interactive material. • Providing a hands-on approach that aids with retention. • Helping students to understand complex subjects and theories. • Giving students the opportunity to experience situations that are “rare
events” that they may not otherwise experience.

Both virtual and augmented reality can support traditional educational methods through: • Letting students experience hazardous environments in a safe way. • Reducing apprehension and embarrassment, which otherwise impede
experimentation in activities like role-playing. • Providing a level of visualizations that are not possible in the traditional
classroom. • Creating a uniform and equal learning experience between distance and
campus based students.

• An entry level VR experience that delivers amazing results.
• All that is required: • An iOS or Android smart phone. • Free “FullDive” app from the app store. • Hand controllers that can be printed • $5 Google Cardboard device
• The “FullDive” app, turns the phone into a VR device with access to a wide range of VR content.
• CQUniversity has put together a MAV team. • Creating a coordinated approach across the University. • Scalable AR and VR content from distance students to VR labs. • About to commence a Community of Practice. • Main priority of MAV in CQUniversity is where it can add to education through
engaging content.

• CQUniversity students have used 3D printed tools and an augmented reality smartphone app to learn complex paramedic skills.
• This enables distance students to practice these skills before attending residential schools.
• App helps students develop correct technique through visual and auditory feedback as the procedure is completed.
