Refreshable braille display

Basic Braille Plus - HIMS inc

In the era of technologies everyone should be provided with access to computer. One of the most challenging innovation is providing access to blind people by transmitting information from the screen to an adaptive device.

Braille display is a peripheral device that allows blind or visually impaired people to interact with a computer. A braille monitor uses the braille system that blind people use to read. Raised dots spell out text that the user traces a finger over to read

In 1995 Handy Tech Braille display in combination with a screen reader makes Microsoft Windows accessible for blind users. Later in 2005 Easy Braille, a super compact Braille display as well as Sophie, the reading system with a natural sounding voice, and Sophie Pro an extended Version of the Sophie, were introduced.

Software

The content of a page is taken from the OS, after it proceeds to be converted into braille characters and sends it to the display. Most of displays are connected via USB, some models have Bluetooth. Modern operation systems have an API for converting content (e.g. UI Automation for Microsoft Windows).

The cost of the display rices up to 15k. Budget models start from around 1300$. The cost depends on number of Braille cells (from 40 to 120). It may have include time-saving features such as Bookworm mode which scrolls pages automatically. On an ordinary Braille display users have to push the advance button about 20.000 times for reading the book completely.

Bad Ergonomics vs. Good Ergonomics

Looking at contrast between bad and good design is useful for designers. Following common practices is not always a cure to avoid unfriendly interface. Let’s look on the example of trendy practice and how to prevent inappropriate usage. Bad Example of Animation While interactive style is an ultimate tool for making web page more appealing it’s also can become noticeable and annoying. When it comes to creating nice pop up window, first priority should be its functionality. Greatest example of over stepping the bounds is Vladyslav Tyzun’s animation concept for a PayPal email receipt, published on Dribbble. It looks tidy and minimalistic. As for a designer it just feels good to enjoy the animation. This solution is, however, superfluous. To get all transaction information user needs to wait 3.5 seconds. Alternative solution could be some simple drop-down receipt. Good Example of Animation Animated solution can be great-looking with elaborate approach Let’s consider Stripe ...

Make yourself look good online 1. Take advantage of your anonymity Communication online leaves an opportunity to be anonymous and you should take an advantage of it. People are tired of watching themselves behaving according to society standards. Going online makes it easier to live your life and share the exact thoughts and experience that close to your heart.

On my experience there were many naive girls in my school who strongly ...

The Review of Paper "Computer vision in Security" Author: Fothul Karim Forhan The paper is the overview on a technology that helps us recognize different patterns and proceed it in a specific format. The focus is set on security field where CV helps to prevent attacks and massive resource looses. The introduction covers a bit of history as well as points to goals of the research. The main part is divided into: Types of CV technologies applied in security matters, security matters that require CV and other safety matters. For me the most fascinating part is CV in financial field. In the given example cv could identify fraudsters by emotional state, the way a fraudster behaves. After the thief is identified, the alarm is enabled automatically and the transaction is terminated. This is a direct example of how cv saves a companies' money. The only thing that missing is lack of illustrations. It'd be great to see face-recognition algorithms visualization. Overall...
