New computer friendly technology built for autistic children

New computer friendly technology built for autistic children

For children suffering from autism, reading for understanding is often challenging but with the help of new technology they can realise their actual potential.

'Hour of Code', a global campaign by Microsoft, commits to increase access to computer science education to youth with a focus on specially-abled children.

The initiative along with c-- an educational hub helping the cause of mentally challenged and autistic children, seeks to introduce coding and computational thinking to promote I-T based opportunities among such children.

"Technology is a promoter of your potential and it doesn't pose as such any threat to the autistic. Such children usually do not want to be told what to do, also they usually do not like eye contact. Therefore, with the technology they are able to do things themselves. It is the only way forward for such children."

4D Visualization

4D-THE MODERN DIMENSION

"4D" is shorthand for "four-dimensional"- the fourth dimension being time. 4D visualization takes three-dimensional images and adds the element of time to the process.

In contrast to 3D imaging diagnostic processes, 4D allows doctor to visualize internal anatomy moving in real-time. For example: Movement patterns of fetuses allows conclusions to be drawn about their development; increase of accuracy in ultrasound guided biopsies thanks to the visualization of needle movements in real time in all 3 planes. So physicians and sonographers can detect or rule out any number of issues, from vascular anomalies and genetic syndromes

Concept Of 4D Visualization

In the field of scientific visualization, the term "four dimensional visualization" usually refers to the process of rendering a three dimensional field of scalar values. While this paradigm applies to many different data sets, there are also uses for visualizing data that correspond to actual four-dimensional structures. Four dimensional structures have typically been visualized via wire frame methods, but this process alone is usually insufficient for an intuitive understanding. The visualization of four dimensional objects is possible through wire frame methods with extended visualization cues, and through ray tracing methods. Both the methods employ true four-space viewing parameters and geometry.

4D Viewing Vectors and Viewing Frustum

METHOD:

4D-HAMMER, involves the following two steps:

(1) Rigid alignment of 3D images of a given subject acquired at different time points, in order to produce a 4D image. 3D-HAMMER is employed to establish the correspondences between neighboring 3D images, and then align one image (time t) to its previous-time image (t-1) by a rigid transformation calculated from the established

correspondences.

(2) Hierarchical deformation of the 4D atlas to the 4D subject images, via a hierarchical attribute-based matching method. Initially, the deformation of the atlas is influenced primarily by voxels with distinctive attribute vectors, thereby minimizing the chances of poor matches and also reducing computational burden. As the deformation proceeds, voxels with less distinctive attribute vectors gradually gain influence over the deformation

ALGORITHM:

it uses the ray tracing algorithm

The global wireless standard for simple, secure connectivity.

Security

Bluetooth adheres to U.S. federal security regulations, ensuring that all Bluetooth devices are capable of meeting and exceeding strict government security standards.

Low Energy

The power-efficiency of Bluetooth with low energy functionality makes it perfect for devices that run for long periods on power sources, such as coin cell batteries or energy-harvesting devices. Bluetooth 5 offers the option of increased range or speed, and it’s always low energy.

Coexists with other technologies

Bluetooth 5 also includes updates that help reduce potential interference with other wireless technologies to ensure Bluetooth devices can coexist within the increasingly complex global IoT environment.

Application:

• The new Bluetooth standard is now ready for action and should progressively roll out into consumer devices from 2017. Promising a serious increase in performance, Bluetooth 5 is ready to meet the needs of a new generation of connected gadgets with even faster data sharing.
• Bluetooth is a widely used wireless communication standard for securely sharing data over short distances between two electronic devices via a specific set of radio waves.
• The technology features in many connected devices, such as laptops, smartphones, wireless headphones and smartwatches, allowing them to connect and communicate wirelessly. Today, Bluetooth plays a key role in the development of the Internet of Things (IoT).

This Gadget Turns Your iPad Into a Powerful 3D Scanner

3D Scanning Comes to the ipad:

    3D printing is an incredible technology, although it requires detailed information about the objects you want to print. For most people, this is a big limitation — it's not like every phone or tablet has a 3D imaging camera. Enter Occipital.

working principle:

The sensor can quickly scan an object or room and gather distance and geometry information to create an accurate 3D rendering. Occipital, the company behind the sensor, said its device can "understand" the data it collects, letting users instantly call up wall dimensions, for example. It even makes use of the iPad's built-in camera

The Structure Sensor is an oblong metal object that attaches to an iPad with a special bracket. It works with apps specifically designed to use the sensor to scan and capture 3D information about an object or environment. You can use the sensor for a wide range of tasks — from object capture to augmented-reality games.

Application:

 Although the sensor is designed for use with the iPad, Occipital makes it easy to plug it into another device.

Sweat Detectors? Tiny Sensors Use Perspiration to Track Health

What it is?

        A soft, skin‐mounted microfluidic device for capture, collection and analysis of sweat.
Sweat could be the next thing wearable devices sense to track your health, researchers say. A new microfluidic skin patch capable of collecting and analyse

Working Principle 

        Imagine if taking a snapshot of your health were as easy as slapping a sticker on you skin. A new study finds that a tiny adhesive sensor can read what's going on in your body based on your sweat, and relay information about your well-being wirelessly to asmartphone. This  type of wearable  

sensor could work as an alternative to blood tests to asses people's health one day, according to the researchers.

Application

The readings collected by the sweat sensor seemed comparable to the current lab-based standards during a trial involving nine volunteers doing indoor cycling. Health readings included sweat rate and sweat loss, pH (an indicator of hydration levels), and concentrations of lactate, glucose, and chloride.
