Applications of Augmented Reality:

Augmented reality has been around for many years, but it wasn’t until the emergence of smartphones equipped with GPS, camera and AR capability that AR came into its own among the public. Augmented reality technology combines the digital world with the real world in the form of live video imagery that is enhanced with computer-generated graphics. AR can be experienced through headsets and displays on mobile devices. The number of AR apps available for the android and iOS devices has expanded dramatically, and are not limited to just games. Retailers are showing tremendous interest in the possibilities of using AR for their business.

Handheld AR Equipment: There is a list of AR software development kits available for Android smartphones and Apple’s mobile devices. These kits give developers the tools needed to add AR elements to their apps.

AR Headsets: Although devices like Microsoft’s HoloLens or Facebook’s Oculus headset are quite expensive. Other companies have started offering headsets at a third of the price the high end headsets like the HoloLens. Most AR headsets operate while tethered to a PC, but it won’t be too long before untethered headsets will be available in the market.

Blockchain technology:

Originally devised in 2008 for the digital currency, Bitcoin, the revolutionary blockchain technology allows digital information to be distributed but not copied. A network of computing “nodes” makes up the blockchain. Each node gets a copy of the blockchain, which is downloaded automatically. It is an incorruptible digital ledger of economic transactions that can be programmed to record online financial transactions. Distributed ledgers can be public or private and vary in structure and size.

Public blockchains need computer processing power to confirm transactions. Information held on a blockchain exists as a shared and continually reconciled database. This database isn’t stored in any single location, which means the records it keeps are made public and easily verifiable. Instead of a single centralized authority, the record’s authenticity can be verified by the entire community using the blockchain.

Blockchain technology provides a new layer of functionality for the internet. It gives internet users the ability to create value and authenticates digital information. There is no centralized version of this information, making it impossible for hackers to corrupt and hence secure. Blockchains are built from 3 technologies:

  • Private Key Cryptography.
  • P2P Network.
  • Program (the blockchain’s protocol).

Authentication and authorization supplied in this way allows for interactions in the digital world without relying on the trust factor. The mechanism of blockchain technology brings everyone to the highest degree of accountability. It prevents missed transactions, human errors, and even exchange done without the consent of the parties involved.

Blockchain security methods use encryption technology that avoids centralized points of vulnerability that can be exploited by computer hackers. It validates a transaction by recording it not only on a main register, but also on a connected distributed system of registers. These registers are connected through a secure validation mechanism. This self-auditing ecosystem with a digital value reconciles every transaction that happens in ten-minute intervals. Each group of these transactions is referred to as a “block”. Once completed, a block goes into the blockchain as a permanent database. Trying to alter or corrupt any information on the blockchain requires a huge amount of computing power, which is practically impossible.

With all its potential benefits and applications, for some, the ever-growing size of the blockchain is considered to be a problem, creating issues of storage and synchronization.

What is 5G technology?

5G is the fifth generation wireless broadband technology that is based on the IEEE 802.11ac standard. Although there is still time for mainstream implementation of this technology, an increasing number of companies have already started gearing up for this new mobile wireless standard. The features and usability of 5G are much beyond the expectation of people. The features of 5G includes,

  • Zero latency.
  • Speed of up to 10 Gbps.
  • Wide range of applications.
  • More software options to upgrade.
  • Faster response time.
  • Ubiquitous connectivity.

While 4G claims to be around five times faster than 3G services, 5G Wi-Fi connections are set to be around three times faster than 4G, starting with 450Mbps in single-stream, 900 Mbps in dual- stream and 1.3Gbps in three-stream. With huge growth seen in the IoT and smart devices, 5G will enable a rapid arrival of a connected future. This new technology offers a wide range of features, which are beneficial for everyone, including students and professionals in various fields. It has the ability to provide uniform, uninterrupted, and consistent connectivity across the world. Medical treatment will become easier for doctors as they will be able to treat patients remotely. Besides increase in bitrate, 5G has also advanced in terms of,

  • Increased peak bit rate.
  • Larger data volume per unit area.
  • Allowing more devices connectivity, concurrently and instantaneously.
  • Lower battery consumption.
  • Better connectivity irrespective of the location.
  • Larger number of supporting devices.
  • Lower cost of infrastructural development.
  • Higher reliability.

Although implementing this technology has many benefits, it has several shortcomings as well. Because of the incompetent technological support in most parts of the world, the claimed speed of 5G is difficult to achieve in all locations. Most old devices would not be compatible with 5G and will need to be replaced, which is an expensive deal. With security and privacy issues yet to be addressed, developing the infrastructure needs high cost as well. The challenges faced by this technology can be categorized into Technological challenges and common challenges. The technological challenges include inter-cell interference, efficient medium access control and network traffic management. Common challenges include standardization to provide dynamic, universal, user-centric, and data-rich wireless services, need for larger infrastructure support, security and privacy concerns of users, and legislation of the Cyberlaw is also an imperative issue.

Starting from the First Generation (1G) in 1980s, we are advancing towards more sophisticated and smarter technology. With greater bandwidth comes faster download speeds and the ability to run complex mobile internet apps on devices. With 5G scheduled for launch in 2020, the impact it will have remains to be seen.

Top Messaging Apps:

Since the appearance of smartphones and the subsequent explosion of mobile apps in the market, low-cost chat and social messaging apps have been proven to be a cheaper alternative to operator-based text messaging via SMS. Traditional SMS text messaging has become old-fashioned with the rise in popularity of these online messaging apps. There are several messaging apps that offer social networking features with improved security. They not only provide the option to send messages, but also offer voice calling, video calling and file-sharing options as well. Many messenger apps offer interesting features like group chats, exchange of graphics, videos, audio messages and even stickers or emoticons. Hers are some of the most popular messaging apps based on the number of monthly active users on both android and iOS devices.

Whatsapp: With over 1.2 billion active users, Whatsapp is the most popular messaging app among smartphone users around the world. This free to use app is very easy to setup using just the phone number. This feature rich app allows users to send text, photos, voice and short video messages to their WhatsApp contacts. The app has continuously added new features like emoji, video calling, and most recently, end-to-end encryption.

Facebook messenger: Social media giant Facebook’s foray into mobile messaging is its messenger app. It is a dedicated messaging app that builds on company’s existing chat network and offers more mobile messaging features. Users can sign in using their facebook account credentials to use the apps features such as send text and voice messages, make voice and video calls to other users. There is also lighter version of the app called Messenger Lite that can run on older Android devices and requires less memory and processing power.

We chat: With over 900 million users, we chat dominates in the Chinese mobile web. This app offers users with features like free instant messaging, video and voice calls, group chat, and multimedia messaging as well.

It is very popular among companies for its business friendly features in its professional version. Even in the face of stiff mobile competition, this old warhorse has stood the test of time.

Whatsapp Payments now rolling in India.

After demonetization, the government has been pushing digital payments among users in India. Whatsapp has reportedly started testing its payments feature in here. It is currently available for select beta users on android and iOS. This new feature will enable users to send and receive money using the Indian government’s Unified Payments Interface (UPI) standard.

What is UPI? It is an instant real-time payment system developed by National Payments Corporation of India facilitating inter-bank transactions. It is built over Immediate Payment Service (IMPS) for transferring funds. Other popular UPI based payments include Tez, BHIM, Phonepe, Paytm, SBI Pay and much more. Users can send and receive money directly from their bank account just by entering the VPA, without the need for knowing the recipient’s name, bank name, account number, IFSC code and other details.

Considering the popularity and large user base of Whatsapp, this new feature will probably give a boost to digital payments in the country. It is supposedly available on WhatsApp version 2.18.21 for iOS devices and version 2.18.41 for Android devices. Apparently, this feature can be accessed through the attachments menu in the chat window. Choosing the payments option in the attachments menu will show a popup with the disclaimer and list of banks to choose from.

Like all other digital payments apps, Whatsapp payments will also have to incorporate high level of security to ensure that user information is safe. It remains to be seen if whatsapp payments is going to offer anything different from its competitors and become a game changer for digital payments in India.

An introduction to Chatbots.

Chatbots are computer programs that can have the ability to mimic human conversations in their natural format including text or spoken language. This is accomplished by using artificial intelligence techniques that includes Natural Language Processing (NLP), image & video processing, and audio analysis. Their most interesting feature is that they can learn from past interactions and become smarter over the time. Chatbots work in two ways:

  • Rule Based: They provide predefined responses from a data base, based on the keywords in the search.
  • Smart Machine Based: They inherit capabilities from AI and adjust their behavior based on customer interactions.

The arrival of this technology is has given rise to new realms of engaging customers and ways of doing business. With instantaneous and personalized customer response that meets customer expectations, chatbots have revolutionized the customer service industry. Powered by Artificial Intelligence (AI), Chatbot intelligence will increase with better use of conversational interfaces, and in future it will be used not only for customer support and retention, but acquisition as well. The objective of using chatbots is not to replace humans, but to bridge the gap between brands and consumers. Although the implementation of chatbots in the call center industry will have huge implications with potentially disruptive technology. Generally, chatbots can be trained with four major types of data projects.

  • Utterance collection: Here, the bot is trained to identify instances where people come up with different ways to ask the same thing.
  • Relevance: Using this, the bot is trained to give relevant responses to real user questions.
  • Intent: Here, the bot learns to judge the user’s intent while they are engaged with them.
  • Entity recognition: This type of data project is used to help the bot understand nuance and context of the conversation.

Currently, front-end chatbots are used in several domains, but are still in the primitive stage. Compared to humans, these front-end chatbots lack empathy and the ability for problem solving. For businesses, chatbots can be used to manage customer queries round the clock without any delay. There are many other advantages of incorporating this technology in business.

  • Interactions are possible through familiar platforms like Facebook chat through API.
  • Easy to interact using a simpler interface.
  • Capability to outperform humans in terms of speed in handling customer queries.
  • Easy to build, cost efficient and improved efficiency.

Chatbots can currently be seen on websites and social platforms to assist customers in their interactions with the brand. Chatbots not only communicates through voice or text, users can now interact with them via graphical interfaces and widgets as well. This technology gives businesses a new way to interact and deliver their messages to customers on chat platforms.

What is LiFi?

Light Fidelity (LiFi) is a wireless optical networking technology that uses light for data transmission. It is designed to use LED light bulbs fitted with a chip that imperceptibly modulates the light for optical data transmission. The LiFi data that is transmitted is received by photo-receptors. Earlier developmental models of LiFi were capable of transmitting data at 150 megabits-per-second (Mbps).

With 10000 times the frequency spectrum of radio, LiFi offers much higher speeds than WiFi. Data transmitted using this technology is more secured as it can’t be intercepted without a clear line of sight. LiFi is ideal for use in environments such as hospitals and aircraft as it does not create interference in sensitive electronics. Li-Fi provides better bandwidth, efficiency, connectivity and security than Wi-Fi and has already achieved high speeds of over 1Gbps under the laboratory conditions. The transmission rate can be further increased to 10Gbps through parallel data transmissions using an array of LED lights. By leveraging the low-cost nature of LEDs, there are lots of opportunities to exploit this new medium.

With increase in the number of devices which access the Internet, the availability of fixed bandwidth in current technology makes it more difficult to enjoy high data transfer rates. Li-Fi was introduced for the first time by a German physicist Harald Hass in the TED Global talk on Visible Light Communication (VLC) in 2011. This revolutionary technology has the potential to change the way we access the Internet, stream videos, receive emails and much more.

The main components of a basic LiFi system includes a high brightness white LED that acts as transmission source and a silicon photo-diode with good response to visible light as the receiving element. To generate any new data stream, the data can be encoded into the light by varying the flickering rate of the LED. LiFi has several applications, from public internet access to auto-piloted cars that communicate through their LED headlights, this technology has potential applications in fields such as education, medicine, disaster management, traffic management, mobile connectivity and much more. The growth in the use of LEDs provides the opportunity to integrate this technology in plenty of environments.

Like any other current technologies, LiFi has its own set of limitations. It requires a near perfect line-of-sight to transmit data to the receiver. Internet cannot be accessed without a light source, which could limit the number of locations where LiFi can be used. Natural light and opaque obstacles can affect data transmission and its speed as well.

What is Machine Learning?

Machine learning (ML) is an application of Artificial Intelligence (AI). It provides systems the ability to learn and improve from experience without being explicitly programmed. The learning process begins with observations and data such as examples provided by us, direct experience or instructions, in order to look for patterns in data and make better decisions in the future. The primary objective of ML is to enable computers to learn automatically, without any human intervention.

The processes involved in machine learning are similar to that of data mining and predictive modeling, which require searching through data to look for patterns, based on which program actions are adjusted accordingly. Social Media giant Facebook uses machine learning to personalize each members news feed. The software uses statistical analysis and predictive analytics to recognize patterns in user data and use them to populate the News Feed. Search and recommendation engines use also use this technology to personalize online ad delivery in near real time. There are many other use cases in machine learning that includes building news feeds, fraud detection, spam filtering, network security threat detection and maintenance.

Machine Learning methods:

Here are the categories of Machine Learning algorithms.

Supervised Machine Learning Algorithms: These algorithms can add what has been learned in the past to new data to predict future events. By analyzing a known dataset, the algorithm produces a function that is used to predict output values. It can also compare outputs, find errors and make modifications accordingly.

Unsupervised machine learning algorithms: These algorithms are used for unlabeled training data-sets and learn how a function can be inferred to describe its structure.

Semi-supervised machine learning algorithms: These algorithms use both labeled and unlabeled data for training. Systems using this method are able to significantly improve learning accuracy. This method of learning is chosen is the given data requires skilled resources to train it.

Reinforcement machine learning algorithms: This learning method enables the system to interact with its environment by producing actions and discovering errors and rewards. In order to maximize performance, these algorithms allow machines and software to ascertain the ideal behavior to determine which action is best in a specific context.

Combining machine learning with AI can make it even more effective in processing large amounts of data. Machine learning enables analysis of this data to accurately identify profit making opportunities and potential risks.

Google Assistant:

Apple’s Siri was introduced with the iPhone 4S back in 2011. Since then, other tech giants like Amazon and Google launched their own apps similar to it. While Amazon’s Alexa assistant was launched in 2014 as part of the Echo home speaker, Google’s Assistant was launched in mid-2016. Google Assistant was positioned as central to almost all products that the company unveiled. This included wireless earphones, smartphones, home speakers and laptops. It offers features so far unmatched by siri. For example, Google’s Home speakers can be configured to recognize people from the sounds of their voices. Here is a list of few features offered by Google Assistant:
