The emerging technologies have a tremendous scope in the current education system. There are many examples of how technology is being used to create engaging learning material with an emotional connect. One such popular aspect of technology is Gaming which mainly focuses on emotions. These days you can find a pool of interesting games on internet – funny games, scary games, and many other adrenalin–rushing games. Games offer a wide range of benefits that are well suited to education, such as challenge, progression, reward, and access to personalized real–time experiences.

It becomes all the more important to introduce these games in education system because in traditional education system, failure is seen as a negative aspect whereas in games, failure is seen as a positive aspect of the gaming experience, motivating the user to perform better. A first time player fails often while playing a game. But with experience, he improves until he eventually becomes an expert and conquers the game. Introduction of such gaming techniques can make our current education system much more interactive, competitive, and student friendly.

Depth–Sensing Cameras that Can Work in Bright Sunlight as well as in the Dark
Depth–sensing cameras, such as Microsoft's Kinect controller for video games, have been widely used as 3D sensors to sense depth. It, however, had a shortcoming that it could not work in bright light, especially in bright sunlight. But now with the invention of a new imaging technology by Carnegie Mellon University and the University of Toronto, this problem has been well addressed.
The researchers created a mathematical model to help program these devices so that the camera and its light source work together efficiently, eliminating the extraneous light or noise that would otherwise wash out the signals needed to detect a scene's contours and gather only the bit of light that camera actually needed.

One prototype based on this model synchronizes a laser projector with a common rolling–shutter camera – the type of camera used in most smart phones – so that the camera detects light only from points being illuminated by the laser as it scans across the scene. This not only makes it possible for the camera to work under extremely bright light or amidst highly reflected or diffused light – it can capture the shape of a light bulb that has been turned on, for instance, and see through smoke - but also makes it extremely energy efficient.

As the depth sensing cameras actively illuminate scenes, they are suitable for use in darkness, such as inside craters, but do not work properly in the regions having high glare or where the sun is at a low angle. With the advent of the new imaging technology, these cameras can work effectively in bright sunlight as well.

Transforming the Traditional Ways of Manufacturing
Traditionally, when designers build something new, the process goes a little something like this: first choose the materials you're going to work with, and then start designing the points, lines, and surfaces that will build the final product. But there is a new technology being tried out that could turn that process on its head. It's called "generative design" and it has computers crunching numbers in a whole new way. In generative design, a computer decides how to manufacture a material and shape that material's design, all at the same time.

This technology could transform the way we make things – from improving designs of bicycle helmets to reshaping bridges and mastering the art of artificial limbs. Structures built in generative design tend to have a highly complex, sometimes organic shape. This is because generative design uses algorithms to calculate the best design for a product based on both the functionality the designer wants, and the environmental constraints and forces acting on the object. With fewer straight lines and planes than traditional computer modeling, the process is more akin to something like bone growth.

The researcher's team at Autodesk has been developing the modeling technology for the past several years. Last month, they moved their computer models into creation mode – trying to find a way to build a better helmet – one that will be both strong and cushiony, but sleeker than the typical foam–goes–on–the–inside, shell–goes–on–the–outside format. Instead, they'll be 3–D printing a helmet in smooth, solid pieces that can have both properties at once: cushioned on the inside, and strong and hard on the outer side, thus making a more comfortable, better–fitting cap.

World's First 'Solar Road' is Generating More Power than Expected
An experimental bike path that also functions as a giant solar cell has far exceeded expectations in the six months it has been in use – and that has scientists eyeing roadways as possible sources of solar energy to power street lights, traffic systems, and electric cars.

SolaRoad, the first–of–its–kind path, opened in November 2014 in Krommenie, a village northwest of the Dutch city of Amsterdam. So far, it has generated enough energy to power a one–person household for an entire year. The path has generated an excess of 3,000 kilowatt–hours and if it is translated to an annual yield, more than the 70 kWh per square meter per year can be generated.

The concrete path is studded with ordinary silicon solar panels that are protected by a centimeter–thick layer of safety glass. The transparent, skid–resistant glass can support bicycles and vehicles as well as pedestrian traffic. Electricity generated by the panels is fed into the electricity grid.

TIET continued its endeavor to train students and faculty of different colleges and universities to enable them to excel in their respective fields. In this endeavor, TIET organized the following workshops and training programs last month:
  • A Two-Day Express workshop was organized on AutoCAD followed by a Building Design Competition Design Heroes at KIIT college, Gurgaon.

  • A workshop on Computer-aided-Designing was conducted at Govt. ITI, BTC PUSA, New Delhi.

  • TIET faculty along with TES Group delivered a short lecture on Raster Design at Bureau of Indian Standards (BIS) headquarter, New Delhi.

  • TIET conduct a Three-Day Faculty Development Program on Emerging Technologies at KIIT college, Gurgaon on 12th September. It will conduct similar workshops on 26th September and 1st October 2015 at the same venue.
