How To Cut, Copy and Paste While Using VoiceOver

Cut, copy and paste is an important feature in iOS. It can be a little tricky for VoiceOver users to use cut copy and paste if you are not familiar with the process. Because it is a little tricky I will walk you through the process step by step.
  1. Select the words you want to cut or copy with the VoiceOver cursor by touching the line or flicking left or right.
  2. Rotate the VoiceOver rotor to either "words" or "lines." To rotate the VoiceOver rotor place two fingers on the screen and turn them left or right. If you select "lines" you will select one lines at a time and if you select "words" you will select one word at a time.
  3. Pinch out with two fingers to begin to select the words you want to cut or copy. VoiceOver will speak which words have been selected.
  4. Rotate the rotor to "edit" mode and then swipe up or down to hear all of the options. It will give you options such as cut, copy, paste, define and more depending on which app you are using.
  5. When you hear the option you want, double tap anywhere on the screen. Now you have copied the text.
  6. To paste the text navigate to a text box and then double tap and hold. Then swipe to navigate to the paste button and then double tap anywhere on the screen to paste the text.
Apple says the following about cut, copy and past with VoiceOver.
"Cut, copy, and paste comes to iPod touch. To bring up cut, copy, and paste options, use the rotor and choose Edit. Flick up or down to choose between the Select and Select All functions, then double tap. If you choose Select, the word closest to the insertion point is selected when you double tap. Pinch to increase or decrease the selection. If you choose Select All, the entire text is selected. When text is selected, cut, copy, and paste options appear on the screen. If you want to undo something, just give iPod touch a shake. You can also flick left or right to choose the undo action, then double tap."

Researchers Find Faster Eyes-Free Typing Solution for Touch Screens

Researchers have developed and faster way to type on touch screens with out seeing the screen. The solution, called BrailleTouch, is perfect for blind smart phone users. BrailleTouch uses the three dots on each side of the screen to represent Braille alphabet. BrailleTouch is designed to be used with the touch screen facing away from the user. The 1st, 2nd and 3rd fingers of both hands are used to touch the six dots. Researchers claim that BrailleTouch allows users to type eyes-free with 92 percent accuracy and 32 words per minutes. BrailleTouch is a prototype app and is not available to the public.

ATLANTA - Feb. 17, 2012 - Imagine if smartphone and tablet users could text a note under the table during a meeting without anyone being the wiser. Mobile gadget users might also be enabled to text while walking, watching TV or socializing without taking their eyes off what they're doing.

Georgia Tech researchers have built a prototype app for touch-screen mobile devices that is vying to be a complete solution for texting without the need to look at a mobile gadget's screen.

"Research has shown that chorded, or gesture-based, texting is a viable solution for eyes-free written communication in the future, making obsolete the need for users to look at their devices while inputting text on them," said Mario Romero, Postdoctoral Fellow in the School of Interactive Computing (IC) and the project's principal investigator.

The free open-source app, called BrailleTouch, incorporates the Braille writing system used by the visually impaired. It has been conceived as a texting tool for any of the millions of smartphone phone users worldwide.

Early studies with visually impaired participants proficient in Braille typing have demonstrated that users can input at least six times the number of words per minute when compared to other research prototypes for eyes-free texting on a touch screen. Users reach up to 32 words per minute with 92 percent accuracy with the prototype app for the iPhone.

"We are currently designing a study to formally evaluate BrailleTouch through both quantitative and qualitative methods," said Caleb Southern, an IC graduate student. "We will measure the typing speed and accuracy of visually impaired users and capture the feedback from study participants in areas such as comfort, ease of use and perceived value."

For sighted users, the research team is exploring how BrailleTouch could be a universal eyes-free mobile texting app that replaces soft QWERTY keyboards and other texting technologies.

"BrailleTouch is an out-of-the-box solution that will work with smartphones and tablets and allow users to start learning the Braille alphabet in a few minutes," said Romero. "It also reduces the need for expensive proprietary Braille keyboard devices, which typically cost thousands of dollars."

The researchers have designed BrailleTouch to address the limitations of soft keyboards, which do not provide tactile feedback, as well as physical keyboards, which often use small and numerous fixed buttons. BrailleTouch is the only iPhone app in existence that uses a six-finger chording process that replicates the traditional Braille keyboard.

The app uses a gesture-based solution by turning the iPhone's touchscreen into a soft-touch keyboard programmed for Braille and requiring only six keys, making it a practical solution for the limited screen real estate on smartphones.

The key feature of the BrailleTouch technology is the use of the six-key configuration so that the keyboard fits on the screen and users keep their fingers in a relatively fixed position while texting. This design allows users to hold their device with the screen facing away from them ¬– cradling the device with their palms or pinkies and thumbs – and to type with a majority of their fingers, identical to typing Braille on a standard keyboard.

The team behind BrailleTouch is led by Romero and IC Professor Gregory Abowd, co-principal investigator. Former IC affiliate Brian Frey conceived the original idea and developed the first prototype and Southern created an improved design. They are conducting usability studies together with James Clawson, a Ph.D. candidate in IC, and Kate Rosier, a master's graduate in Digital Media and bachelor's graduate in Computational Media.

The research group has developed iPhone and iPad versions of BrailleTouch and is currently working on Android versions. The app recently won the MobileHCI 2011 competition for design at the MobileHCI conference in Stockholm, Sweden.

BrailleTouch will be demonstrated at the Abilities Expo-Atlanta 2012, taking place Feb. 17-19 at the Georgia World Congress Center. A video of BrailleTouch in action is available at the following link:

This project was supported in part by the Rehabilitation Engineering Research Center for Wireless Technologies (Wireless RERC), which is funded by the National Institute on Disability and Rehabilitation Research (NIDRR), United States Department of Education, under grant number H133E110002. 

Scanner Pro Review

Scanner Pro is an app for the iPhone, iPad and iPod Touch. It works best with the iPhone because it has a higher quality camera. Scanner Pro allows you to take a picture of a multi-page document and then convert the images into a PDF file. Images can be taken with the camera or imported from the camera roll. When using the camera to capture an image there is an option to have the picture taken when the camera is perfectly still for better image quality.

Scanner Pro allows you to take pictures of multiple pages before saving them to a PDF which speeds up the process of scanning multiple pages. Once you have taken the pictures of the document you can change the contrast and brightness. Scanner Pro can automatically detect the edges of a document but it does do not do as good of a job at detecting edges as other scanner apps such as TurboScan and JotNot.

The app struggles even more if the document is on a light background. The inability of Scanner Pro to consistently detect the edges is a major downside. If Scanner Pro does not recognize the edges of the document automatically you can adjust the edges manually but this takes time and slows down the process considerably. Once you adjust the edges Scanner Pro has great features to manage and share your document. You can send documents by email, iDisk, WebDAV services, Evernote, Google Docs and Dropbox. The app allows you to share you documents over Wi-Fi as well. Another cool feature allows you to password protect the entire app or individual documents. Scanner Pro costs $6.99 in the App Store.

Scanner Pro is a well done app but the problems detecting edges really slows things down. Because of this one problem I would recommend JotNot or TurboScan instead. If Readdle, the maker of the app, fixes the edge detection problem it would be a different story.

Oxidizing Agents

If you are a Chemistry student then you will be familiar with the terms like atomic structures, isotopes, halogens, and oxidizing agent. To understand what an oxidizing agent means in the world of science, it is important to delve deeper into its definition, examples and properties. Many times students find it confusing to understand the aspects clearly. In such bases, you can always seek help from the private science tutors. In this article, we will discuss about an oxidizing agent.

According to the scientific definition, oxidizing agent is a chemical compound that conveniently transfers atoms of oxygen; and in a redox chemical reaction, it gains electrons. It is also identified as an oxidizer or oxidant. Thus, it can also be cited as a chemical substance which voluntarily transfers oxygen atoms and gains electrons in a state of redox chemical reaction.

Several studies have allowed scientists come to the conclusion that oxidizing agents usually pair with the reducing agents that are substances that gain electrons in a state of redox reaction. There are also several claims that prove that they may be known as oxygenation reagents due to its property of transferring oxygen-atoms in a particular reaction. The basic of oxygenation is very simple; and most metal and non-metals get oxidized to a particular point of magnitude.

Furthermore, the properties of these agents also state that the atoms in a certain molecule can be simply assigned an oxidation number. Now, this oxidation number changes consequently when an oxidant happens to act on a certain substrate. Thus, in a state of redox reaction, there is the possibility for the oxidation numbers to alter under the reacting circumstances.

Some of the common oxidizing agents include Oxygen (O2), Chlorine (Cl2), Iodine (I2), Fluorine (F2), Ozone (O3), Bromine (Br2), Chlorate (CIO3-), Nitric Acid (HNO3), Dichromate (Cr2O72-), Hypochlorite (OCI-), Chromate (CrO42-), Manganate (MnO42-), and Chromium Trioxide (CrO3). Many of the above mentioned chemical compounds have properties that are strong, while others are simply the best agents in a chemical reaction. Thus, the agents need to be assorted in different categories.

The molecules, ions, and atoms that have astonishing affinity of electrons, act like good oxidizing agents. For example, fluorine (F2) is recognized as the strongest one in the group. This is because the elements like metals, asbestos, quartz ruptures into flames in the presence of fluorine.

Linear Motion System

Linear motion is the most basic of all motions. Objects that are not subjected to external forces will progress uniformly in a straight line permanently. Linear Motion is the movement along a line or length of area. Linear motion can be uniform at a constant speed, or non-uniform with fluctuating velocities (non-zero acceleration). The motion of an object along a line can be described by its position (x), which differs with the amount of time (t). Linear motion is sometimes called rectilinear motion.


A cam follower system is a system/mechanism that uses a cam and follower to create a specific motion. The cam is in most cases merely a flat piece of metal that has a shape or profile machined onto it. This cam is attached to a shaft which enables it to be turned by applying a turning action to the shaft. As the cam rotates it is the profile or shape of the cam that causes the follower to move in a specific way. The movement of the follower is then transferred to another mechanism or another part of the mechanism.


Actuators are devices that put the Linear motion system into automatic action. Actuators are used in a wide variety of applications, from industry machines producing products to computers starting up. Whichever type of actuator you need, there are several different types that can help you achieve putting things into motion. Shapes and styles distinguish actuators by use. There are three types of linear actuators, including basic, compact, and rodless cylinders. Both the basic and compact cylinders are best used when needed for a individual or dual action. Rodless cylinders are best used for long stroke applications in magnetic or mechanical systems. Another type of cylinder is the guided cylinder. This will provide a more stable precise movement that will eliminate bending.


Roller Slides, sometimes called crossed roller slides,are no motor linear slides that provide high precision linear movement for equipment powered by inertia or by hand. Roller slides are based on roller type bearings, which are frequently crossed to provide heavy load capabilities and more precise movement control. Roller Slides are mainly used in industries such as manufacturing, medical and telecommunications, and are versatile,with the ability to be adjusted to meet multiple applications which typically include clean room, vacuum environments, material handling and automated machinery. Roller slides work similar to ball bearing slides, except that the bearings are cylinder-shaped instead of ball shaped. The rollers cross each other at a 90 angle and move in between the four parallel rods that surround the rollers. The rollers are between "V" grooved bearing raceways, one being on the top and the other at the base. The travel ends when it meets the end cap. Typically, bases are constructed from aluminum and the rods and rollers are constructed from steel. Ball bearing slides are the most common type of linear slide. Ball bearing slides offer smooth precise movement along a guide rail, aided by ball bearings housed in the base,for increased reliability. Ball bearing slide applications normally include robotic assembly, cabinetry, high-end appliances and clean room settings, which primarily serve the manufacturing industry. For example, a widely used ball bearing slide in the furniture industry is a ball bearing drawer slide. Linear motion systems play an integral role in all of our lives and will continue to be important as we explore robotics and other technological advancement.

Microtubules Function

Biology is an interesting subject as it deals with the various characteristics of living entities. As a student of biology, you will be introduced to the study of cells. It is both interesting and complex at the same time. Many times students find it difficult to understand every aspect of cell structure in a classroom instruction. In such cases, you can seek help from a professional biology tutor who can help you understand every aspect of the cell structure and the various functions. In this article, we will discuss about the function of microtubules.

Microtubules are known as one of the most significant constituents of cytoskeleton of a cell. The diameter is 25 nanometers, and the length varies between 200 nanometers to 25 micrometers. The microtubules usually serve as the structural constituents within a cell and they take part in diverse cellular processes which are important for the existence of a cell. This process involves cytokinesis, mitosis, and vesicular transport.

In cytology, you will learn about the structure of different cell components. The microtubules are basically polymers of α and β tubulin dimmers. In the case of protofilaments, the tubulin dimers polymerize from end to end. After that, the protofilaments create bundles of void cylindrical filaments. Typically, they must organize themselves in an inadequate helix, where one turn of the helix comprises 13 tubulin dimers, each of which is from a dissimilar protofilament. Another prominent characteristic that helps in microtubules function is its weird polarity.

Now, let's find out regarding the function of microtubules. In mitosis, the process is assisted by a subgroup of microtubules, which are known as the astral microtubules. They usually originate from a centrosome, which do not attach to a kinetochore. The astral microtubules usually build up in the actin skeleton, and they interrelate with the cell cortex to help in direction of spindles through cell division.

They are usually organized around centrosomes in the form of radial arrays. The astral microtubules functions in cycle with the specialized dynein motors, which are leaning with the light chain section attached to cell membrane and the vibrant portion attached to microtubule. This further allows for the dynein contraction to pull centrosome near the cell membrane, thus supporting the cytokinesis in plants and animals.

These microtubules function as the conveyor belts inside the cells. They help in the movement of granules, vesicles, and organelles such as mitochondria and chromosomes. There are many such interesting facts regarding cell structure and the various functions of the components. You can consider hiring a Biology tutor to help you gain an in-depth knowledge.

Organic Chemistry

Organic chemistry is an important part of Chemistry that deals with the carbon containing compounds. Though quite interesting, students sometimes find it difficult to understand the concept clearly. If you need extra help outside classroom instructions then you can consider seeking help from a private Chemistry tutor who specializes in the organic branch. In this article, we will discuss about the diverse properties, composition, structure, behavior and the changes that a matter undergoes under different conditions.

As already stated above, organic chemistry deals with the compounds containing carbon. This branch of Chemistry deals with the structure, naming, synthesis and composition of the carbon compounds; and its studies their behavior when reacted with other substances. The best illustration is that of glucose which is identified with the chemical formula C6H12O6. Though carbon is the fundamental element of study for this sub-branch, a compound which doesn't contain hydrogen is not organic. To further give you a clearer idea, let me tell you that carbon dioxide and carbon monoxide are not organic compounds.

While studying this fascinating branch of science, you also come to known about the significance of the chemical bond that is formed between hydrogen atom and carbon atom. However, an organic compound may also comprise of other elements. In the past, it was believed that the compounds that are derived entirely from living organisms are organic. However, later in the 19th century, the manmade organic compound discovered by scientists was a major milestone.

If you are interested in the subject and you wish to take up a career in this field then you must learn the basic facts about it. Those who specialize in organic chemistry are known as the organic chemists. This sub-branch is used for various purposes, and almost all macromolecules present in living organisms are organic compounds. You find carbon as well as hydrogen in the formula of proteins, nucleic acids, carbohydrates, and lipids. The list of organic compounds includes plastics, plant fertilizers, clothing, and the products that are supported by fossil fuels. This implies that imagining life without the organic compounds is not possible.

According to the scientific reports, there are over six million organic compounds found on earth. In these products the amount of carbon compounds is much higher than the remaining compounds, all combined together. Thus, this is an essential and important branch of Chemistry that has several applications in real life. An expert Chemistry tutor help you get a clearer understanding and guide you to take up a career in this field.

TurboScan App Review

TurboScan is a app for the iPad, iPhone and iPod Touch. The app uses the built in camera to capture a document and convert the image to excellent quality PDF files. TurboScan is $1.99 in the App Store. The app will not work very well with the iPad or iPod Touch because they do not have high quality cameras like the iPhone. The app has a simple interface that is easy to learn. It allows you to capture documents by taking a picture with your iPhone camera or import one from your album. TurboScan also has an option to take three pictures of the document for better accuracy. TurboScan also allows users to scan documents that are more than one page.

Once you have taken the picture of your document TurboScan detects the edges of the document and makes a PDF file. The apps has a few sharing options but not as many as JotNot Pro. The sharing include email and a really nice option called "email to myself" witch allows to quickly email your self the documents you have created.

Once you have your documents on your computer you can open them with Kurzweil to use all of Kurzweil's features such as read aloud and note taking. The PDF files created are crisp and clear.
