RealityPrime is a technology blog and consultancy specializing in imagining the future of human-computer-interaction and helping to realize it through thoughtful, often disruptive design and engineering. The company has been around since 1997; the blog since 2003.


Avi Bar-Zeev has spent the last 23 years imagining new technologies and then helping to bring them to life, in projects as diverse as virtual earths, flying robots and mixed-reality wearables.

Microsoft recently announced “HoloLens,” for which Avi did the earliest concept and prototyping work in 2010. What was originally called “Screen Zero” is now poised to change the way we interact with computers over the next decade. He has close to 40 patents granted or applied in areas such as augmented reality, communications and geospatial technologies.

Avi also co-founded Keyhole, Inc., designing and building the first instance of Google Earth. He built the 3D user experience and much of the client-side architecture.

Before that, he helped develop Disney’s Aladdin’s Magic Carpet VR Ride and went on to lead or influence other interactive 3D experiences for Disney, including the VR rollercoaster and virtual jungle cruise.

Throughout his career, he’s been involved with cutting edge startups like Intrinsic Graphics (3D games middleware), F5 Networks (scalable web services), and Linden Lab, developing core technologies for Second Life, including their procedural 3D object system that instantly builds 3D worlds.
