We were happy to have Prashanth Balasubramanian of lastbit.io over at Pramati Chennai last weekend - 8th and 9th of Sep 2018 - for a workshop towards understanding blockchain tech from the ground up.

Design frameworks and guidelines are a plenty for traditional 2D mobile applications, whereas AR applications and its updates are relatively new with no standard guidelines as such. We look at the current recommendations made by practitioners in the light of Don Norman’s design principles. Table of contents Primer Design Appearance Clues Interaction Feedback Experience Google guidelines in terms of Don Norman’s Design Conclusion Primer Almost all mobile AR applications are 2D applications with basic AR functions and its necessary to find ideal conditions for using the app in the real world.

Approximate biometrics are often required for effective online shopping experience, for example, for clothing, eyewear and footwear. We experimented with Mask-RCNN based object segmentation for measuring human feet with the intention of recommending appropriate footwear, which we talk about in this post.

This post will give you an insight of our experiments and results with AR tools like ARCore, ARKit and Vuforia in terms of features. To understand this blog better, kindly read our precursor to this one here. Since the features of these tools are largely familiar exploring and comparing them in terms of stability would give us new and better perspectives. Table of contents Fusion in AR Vuforia vs ARCore/ARKit Conclusion Fusion in AR Google and Apple have made a giant leap into AR space with the release of ARCore and ARKit.

I’ve been thinking about a few aspects of smart contracts and blockchain tech - especially public blockchain tech - and I have some lingering doubts that I’d like to capture here for any of you to attack.

With the developments happening in the realm of software and hardware breaking new ground daily, it is not far that our reality can be manipulated to suit our everyday lives and enhance our evolution. Welcome to a world of new reality. Augmented Reality manipulates existing dimension giving us a better world view. The rapid growth of mobile technology and ease of application development processes has given the push to develop Augmented Reality applications at a large scale.

Overview: There are a lot of buzz going around in the Blockchain space. No doubt it is a very robust technology that resembles the internet in the early ‘90: It packs the potential to change the way we live, work, consume and interact. As a lot of Dapps - Decentralize applications, Blockchain based applications, are being developed these days, it is very important to think of what are the use cases that should go for Blockchain and what should not or not needed.

Those who are working on Blockchain, especially on Ethereum, must have heard about Smart Contracts. They are fully fledged programs, written in Solidity - language similar to javascript, that runs on Ethereum blockchain. When contracts get compiled, they get converted into opcode - instructions to be executed on the machine - and execution of these opcodes consumes Gas - Gas is the execution fee for every operation made on Ethereum. While writing contract code we have to be very careful otherwise, a user can end up losing a lot of Gas.

I am going to write this topic in couple of blogs. So that reader will get complete exposure of oracle services providers, like Oraclize in particular. In my first blog post I will try to give a brief overview of Oracle services. Basically dealing with questions like, What are Oracles? What is Oraclize? What is the use of such services? Etc. In the subsequent blog, we will try to use the Oraclize service with our smart contract and further we will take a deeper look into, how it works under the hood?

Here at Imaginea Labs, we are exploring the true power of gpu-computing by analysing its way of launching a kernel, running 1000’s of thread blocks simultaneously, threads doing memory accesses in terms of global/shared and the optimized way to do so, doing atomic operation in threads when needed, optimizing threads to run more efficiently and faster.

In this post, we talk about cuda architecture and various experiments done on a use case with a brute-force approach to test and explore the gpu computation limits. We’ve had modest success in bringing out the best of gpu and faced some intriguing situations and results along the way.
