Lesson synopsis

3D glassesWith the mass production and availability of low cost and robust head-mounted displays (HMDs), there has been increasing interest in virtual reality technologies - for example the Oculus Rift, HTC Vive, Samsung VR Gear, Microsoft HoloLens, and Sony’s PlayStation VR. These display technologies are based around artificial stereo images, and provide a view with illusions of 3D depth in virtual environments. Students will use the scientific method to study ‘anaglyph’ (movie 3D) technologies to model computer science design and learn how stereo images create the illusion of 3D.

Age Levels

11 - 14 years

Objectives

Introduce students to
how VR technologies exploit human depth perception,
the use of stereo images to provide the illusion of 3D depth,
use the scientific method to compare anaglyph technologies.

Anticipated learner outcomes

Students will be able to
explain how VR technologies are based on stereoscopic images
explain how anaglyph technology provides the illusion of 3D
analyze the trade-offs between green/red, and red/cyan techniques
demonstrate how to align two images to create 3D illusions.
Router
Sandra Lerner

It is difficult to imagine a time when computers were not capable of sharing information and resources with great ease. Sandra Lerner pushed the boundaries of network computing as one of the co-founders of Cisco Systems, which introduced one of the first commercially viable routers. The router was born while Sandra was working at Stanford University in the 1980’s after earning her Master’s degree there in Computer Science. To avoid the tedious task of transferring information between computers using floppy disks, she and co-founder of Cisco, Leonard Bosack, created a local area network, or LAN, between their campus offices using a multiprotocol router that Bosack developed. Shortly thereafter the pair started Cisco Systems, and began selling the router which was a success, because it could work with so many different types of computers. After Leaving Cisco in 1990, Lerner started the trendy cosmetics company Urban Decay and became a philanthropist and avid activist for animal rights.

@ symbol
Ray Tomlinson
Ray Tomlinson

Have you ever considered that someone, at some point, was in a position to choose what symbol would be used separate the user from their location in an email address? That person, it turns out, was Ray Tomlinson, and in 1971 he chose "@". Tomlinson is credited with demonstrating the first email sent between computers on a network, and when asked what inspired him to make this selection he said, “Mostly because it seemed like a neat idea.”

After completing his Master’s degree at MIT in 1965, Ray joined the Information Sciences Division of Bolt Beranek and Newman Inc. of Cambridge, Massachusetts. Since then he has made many notable contributions to the world of network computing. He was a co-developer of the TENEX computer system that was popular in the earliest days of the Internet; he developed the packet radio protocols used in the earliest internetworking experiments; he created the first implementation of TCP; and he was the principle designer of the first workstation attached to the Internet.

Bletchley Park
Dr. Sue Black
Dr. Sue Black

Dr. Sue Black has demonstrated the power of social networking. She used Web 2.0 technologies to help raise awareness of, and critical funding for, Bletchley Park, the UK World War II center for decrypting enemy messages. She has also been an active campaigner for equality and support for women in technology fields, founding a number of online networking platforms for women technology professionals. A keen researcher, Dr. Black completed a PhD in software measurement in 2001. Her research interests focus on software quality improvements. She has recently won the PepsiCo Women's Inspiration Network award, been named Tech Hero by ITPRO magazine and was awarded the first John Ivinson Award from the British Computer Society. In 2011 Dr. Black set up The goto Foundation, a nonprofit organization which aims to make computer science more meaningful to the public, generate public excitement in the creation of software, and build a tech savvy workforce.

RISC processor
John Hennessy
John Hennessy

Have you ever wondered how computers can execute complex commands in mere seconds? John Hennessy is a pioneer of reduced instruction set computing (RISC) architecture which employs small, highly-optimized sets of instructions to greatly enhance computer performance. He was instrumental in transferring the technology, specifically MIPS RISC architecture, to industry. He co-founded MIPS Technologies and co-authored the classic textbook with David A. Patterson, on Computer Architecture.

As Stanford faculty he rose to be the Chairman of the Computer Science Department, Dean of the School of Engineering, then Provost and finally the President of Stanford in 2000 (and till date). Hennessy holds a Master’s and Ph.D. in Computer Science from SUNY Stony Brook. He is an IEEE Fellow and was selected to receive the IEEE Medal of Honor in 2012. Hennessey also launched significant activities that helped to foster interdisciplinary research in the biosciences and bioengineering at Stanford.

Turing machine
Alan Mathison Turing
Alan Mathison Turing

Did you know that computing has been used in military espionage and has even influenced the outcome of major wars? Alan Mathison Turing designed the code breaking machine that enabled the deciphering of German communications during WWII. As per the words of Winston Churchill, this would remain the single largest contribution to victory. In addition, he laid the groundwork for visionary fields such as automatic computing engines, artificial intelligence and morphogenesis. Despite his influential work in the field of computing, Turing experienced extreme prejudice during his lifetime regarding his sexual orientation. There is no doubt that computers are ubiquitously part of our lives due to the infusion of Turing’s contributions.
