VR vs AR vs MR➢ Virtual reality - Fully virtual immersion

➢ Augmented reality - Basic visual overlay

➢ Mixed reality - Anchored visual overlay

Types of VR➢ 360° Video➢ Hyper immersive

○ Stationary○ Mobile

➢ Observer

Real world applications➢ Gaming➢ Industrial ergonomics

○ Engineering○ Monitoring○ Prototyping

➢ Design○ Planning○ Demos

➢ Education

Real world applications➢ Gaming➢ Industrial ergonomics

○ Engineering○ Monitoring○ Prototyping

➢ Design○ Planning○ Demos

➢ Education

Education➢ Environment -

○ Nature in classroom

○ Dangerous places➢ Equipment -

○ Damage control○ Accessibility○ Simulators

HTCVive➢ Erasmus

project- ○ ViMeLa Project ○ Creating a

Mechatronic Lab in VR environment

Samsung GearVR

Input types➢ Gaze➢ Integrated controls➢ External controller

○ Without positional tracking: PS4 Controller○ With positional tracking: Vive Controller

➢ Gestures○ Depth sensors: Microsoft Kinect○ Motion capture tracking: Vicon

Types of feedback➢ Sight (vision)➢ Hearing (audition)➢ Touch (somatosensation) ➢ Smell (olfaction)➢ Taste (gustation)

Visual Feedback80% of our information from the external environment

Visual Feedback Hardware➢ HTC Vive➢ Oculus Rift➢ Samsung GearVR➢ Google Cardboard➢ Google Glass➢ Microsoft Hololens➢ Daqri Smart Glasses/Helmet➢ ODG Smartglasses

Audio Feedback➢ Draws a lot from modern FPV games

➢ Directing attention

Touch Feedback➢ VRgluv➢ KOR-FX➢ EXOS

Smell Feedback➢ Feelreal Sensory Mask➢ Nosulus Rift

Taste feedbackMeta-Cookie

Best practices➢ Do’s

○ Fade from black and fade to black○ Non-obscuring GUI○ Simplistic GUI○ Correct height and body size

➢ Don’ts○ Acceleration○ Zoom in and out○ Moving the user without their consent○ Lack of a floor

Breaking immersion➢ Latency➢ Animation quality➢ Audio and video quality➢ Overlay accuracy

➢ Hardware weight➢ Hardware reliability

Product testing➢ Test with non-tech savvy users

➢ Don’t give users a bad first impression

➢ Easy to use / natural controller and button
