GOOGLE GLASS



Google Glass is a wearable computer with an optical head-mounted display (OHMD) that is being developed by Google in the Project Glass research and development project, with a mission of producing a mass-market ubiquitous computer. Google Glass displays information in a smartphone-like hands-free format, that can communicate with the Internet via natural language voice commands. 



While the frames do not currently have lenses fitted to them, Google is considering partnerships with sunglass retailers such as Ray-Ban or Warby Parker, and may also open retail stores to allow customers to try on the device. The Explorer Edition cannot be used by people who wear prescription glasses, but Google has confirmed that Glass will eventually work with frames and lenses that match the wearer's prescription; the glasses will be modular and therefore possibly attachable to normal prescription glasses. It is necessary to remove a small screw in order to move the Google Glass from one frame to another.



Glass is being developed by Google X, which has worked on other futuristic technologies such as driverless cars. The project was announced on Google+ by Project Glass lead Babak Parviz, an electrical engineer who has also worked on putting displays into contact lenses; Steve Lee, a product manager and "geolocation specialist"; and Sebastian Thrun, who developed Udacity as well as worked on the autonomous car project. Google has patented the design of Project Glass. Thad Starner, an augmented reality expert, is a technical lead/manager on the project.

Test your Programming skills

PONJESLY COLLEGE OF ENGINEERING
TEST YOUR C- SKILS
  1. What will be the output of the following program?
#include<stdio.h>
int x= 40 // Global Declaration
void main()
{
int x=20; // Local Declaration
printf(“\n%d”, x);
}
  1. What will be the output of the following program?
#include<stdio.h>
void main()
{
int x= 40 //Local Variable
{
int x=20; // Most Local variable
printf(“\n%d”, x);
}
printf(“\n%d”, x);
}
Answers:
  1. 20, Whenever there is a conflict between a local variable and a global variable, the local variable will get the priority.
  2. 20 40, Now both are local variables. In this case the most local variable will get the priority.

5. 8,17,33,67,133, ?


a) 264 b) 265 c) 266 d) 267









ANSWERS:


  1. b
(15*2) + (8/2) =34, (6*2) + (12/2) =18 Hence (5*2) + (40/2)=30
  1. c
See the difference between the numbers outside the brackets and multiply the result by 2.
  1. a
514/2 +1=258, 258/2 +1=130, 130/2 +1=66, 66/2 +1=34
  1. c
See the horizontal rows. 15+7-10= 12. Therefore 25+5-7=23
  1. d
8*2+1=17, 17*2-1=33, 33*2+1=67, 67*2-1=133,133*2+1=267.
