A text recognition technology company, MicroBlink has been developing a powerful engine for mobile phone cameras for the past two years and now, they have made the world’s first camera calculator. PhotoMath is an app that allows you to scan a mathematical equation and solve it immediately along with step-by-step instructions on how to solve it.
PhotoMap is the right tool that will help students check their math homework problems and show them the steps to achieve the correct answer. PhotoMap will also help the parents revise the math lessons that they learnt long time back. However, the teachers might not like PhotoMap because it could be used in a wrong way by the students. They might end up blindly copying down the answers from the app without even understanding the mathematical concepts.
PhotoMap is currently able to handle a variety of mathematical problems, including decimals and fractions, powers and roots, arithmetic expressions and simple linear equations. Nearly all the mathematical problems, as long as the problem is from middle school mathematics because it cannot help you with the trigonometry and calculus for now but would be added soon enough. Also, the app can only solve printed problems and not the handwritten ones. So, if your teacher makes you copy problems on a piece of paper; then, you cannot use the app to solve the questions and you will have to solve them yourselves. PhotoMath is very fast and accurate and also showcases the new technology.
How PhotoMath works
Technical Working: PhotoMath uses video frames and combines the OCR results of the consecutive video frames. MicroBlink also provide a free Software Development Kit for PhotoMath.
User Guide: Hold your phone directly above the equation and try to get it within the frame, drag to adjust the size and shape of the frame. Wait for few seconds and the result will appear on the screen in red colour. To know how to solve the equation, tap the Steps button and to view step-by-step instructions, swipe up and down or tap the arrow buttons. The app allows you to see the recent scans, turn on phone’s LED, see the steps from the last problem you scanned and also see a brief tutorial on how to get started with the app.
