EyeVerify's Mobile Authentication Technology Relies on Eye-Vein Scanning to Let You Vie... - 0 views

  • Typing a password into your smartphone might be a reasonable way to access the sensitive information it holds, but a startup called EyeVerify thinks it would be easier—and more secure—to just look into the phone’s camera lens and move your eyes to the side.
  • EyeVerify’s software identifies you by your “eyeprints,” the pattern of veins in the whites of your eyes. Everybody has four eyeprints, two in each eye on either side of the iris. The company claims that its method is as accurate as a fingerprint or iris scan, without requiring any special hardware
  • Rush says the software can tell the difference between a real person and an image of a person. It randomly challenges the smartphone’s camera to adjust settings such as focus, exposure, and white balance and checks whether it receives an appropriate response from the object it’s focused on.

  • The look of the veins in your eyes changes over time, and you might burst a blood vessel one day. But Rush says long-term changes would be slow enough that EyeVerify could “age” its template to adjust. And the software only needs one proper eyeprint to authenticate you, so unless you bloody up both eyes, you should be able to use EyeVerify after a bar fight
  • Indeed, EyeVerify still needs to do more to prove that. Rush says that in tests of 96 people, the eyeprint system was 99.97 percent accurate. The company is working with Purdue University researchers to judge the accuracy of its software on 250 subjects—or another 500 eyes.

Learning Styles and Children | Funderstanding - 0 views

  • 20 to 30 percent of learners remember through hearing, 40 percent retain information visually, and the rest either have higher memory retention after writing something down or through real-life activities.
  • There are three learning styles – visual, auditory, and kinesthetic and tactile.
  • Visual Learners Visual learners like having information presented to them in an eye-catching way, have strong visualization skills, and to see the “big picture.” Enjoy a fun activity with visual learners encouraging their language and reading skills. Tie the activity into the child’s homework by using vocabulary or spelling words for an upcoming test. Help the child create a list of nouns, verbs, adjectives, and pronouns to use for the activity. If they have a list of vocabulary or spelling words they need to memorize for school, they can be added to the list. Kids can select a color for each type of word and then write them onto flashcards using the coordinating color for each word group (green for nouns). Have the child place the cards in stacks according to color/type. Discuss with the child that they will be creating a visual language story using the words by placing them into sentences and a finished story. This encourages visual learners to see the big picture and understand the final outcome of the activity. Once the child has begun forming sentences, he can arrange them to form a story, working until all the words have been used. Tap into his auditory and kinesthetic/tactile learning, and his active processors, by having him read the story out loud while acting it out.

Where Speech Recognition Is Going - 0 views

  • “I think speech recognition is really going to upend the current [computer] interface.
  • “We’re at a transition point where voice and natural-language understanding are suddenly at the forefront,
  • Jim Glass, a senior research scientist at MIT who has been working on speech interfaces since the 1980s, says today’s smart phones pack as much processing power as the laboratory machines he worked with in the ’90s. Smart phones also have high-bandwidth data connections to the cloud, where servers can do the heavy lifting involved with both voice recognition and understanding spoken queries. “The combination of more data and more computing power means you can do things today that you just couldn’t do before,” says Glass. “You can use more sophisticated statistical models.”

  • Siri,
  • But voice functionality is built into Android, the Windows Phone platform, and most other mobile systems, as well as many apps
  • Nuance is at the heart of the boom in voice technology
  • , Nuance hopes to put its speech interfaces in many more places, most notably the television and the automobile
  • Meanwhile, the Sync entertainment system in Ford automobiles already uses Nuance’s technology to let drivers pull up directions, weather information, and songs. About four million Ford cars on the road have Sync with voice recognition. Last week, Nuance introduced software called Dragon Drive that will let other car manufacturers add voice-control features to vehicles
  • “It’s astonishingly accurate,” says Brian Phelps, CEO and cofounder of Montrue and himself an ER doctor. “Speech has turned a corner; it’s gotten to a point where we’re getting incredible accuracy right out of the box
  • Sejnoha believes that within a few years, mobile voice interfaces will be much more pervasive and powerful. “I should just be able to talk to it without touching it,” he says. “It will constantly be listening for trigger words, and will just do it—pop up a calendar, or ready a text message, or a browser that’s navigated to where you want to go

Ten Steps Toward Universal Design of Online Courses: Home Page - 0 views

  • Another way that color is sometimes used to convey meaning is to differentiate items in a list. For example, a professor may write the following: "All assignments in red must be completed in APA style." This poses a problem for students who are blind and students who are color blind. The use of color is not discouraged altogether. There are definite advantages for other students. It is possible to meet the needs of all of these students, as illustrated in this example:
  • 9) Convert PowerPoint™ to accessible HTML.
  • 10) If it's auditory make it visual; if it's visual make it auditory.

  • Students who use assistive technology - Currently, some of the testing tools have compatibility problems with some screen reader technologies. This occasionally results in the screen reader program crashing during an exam. A good practice would be to have a mock exam available for students to try so that they will know ahead of time if their assistive technology will work with your exam. If it does not, an alternate version of the exam will need to be provided

      Having a test exam for learners with disabilities is something that I never thought about before, but it is a great idea!
  • Black text on a white or light background is the most readable.
    • Nick Martin
       
      Black and white might sound really boring, but it does make it more readable!  I'm sure that we have all come across some websites with some wacky color combinations that make our eyes hurt :(
  • Teach students using a PC to right click on the content they wish to print and choose print. This will allow them to print only the content in that frame.
  • Use concise, meaningful text for links. Like this: Writing Good Link Descriptions Not this: Click here for information on writing good link descriptions
  •  
    This website provides good suggestions for making online courses accessible for both students with disabilities and without disabilities. This website also applies many of these suggestions in its actual design!

How To Increase Higher Order Thinking - 0 views

  • Parents and teachers can do a lot to encourage higher order thinking, even when they are answering children’s questions
  •  “Don’t ask me any more questions.” “Because I said so.”

  • Level 1. Reject the question.
  • Level 2. Restate or almost restate the question as a response.
  • Level 3. Admit ignorance or present information.
  • Level 4. Voice encouragement to seek response through authority.
  • Level 5. Encourage brainstorming, or consideration of alternative explanations.
  • Level 6. Encourage consideration of alternative explanations and a means of evaluating them.
  • Level 7. Encourage consideration of alternative explanations plus a means of evaluating them, and follow-through on evaluations.
  • When brainstorming, it is important to remember all ideas are put out on the table. Which ones are “keepers” and which ones are tossed in the trashcan is decided later.
  • Encourage Questioning. Divergent questions asked by students should not be discounted. When students realize that they can ask about what they want to know without negative reactions from teachers, their creative behavior tends to generalize to other areas. If time will not allow discussion at that time, the teacher can incorporate the use of a “Parking Lot” board where ideas are “parked” on post-it notes until a later time that day or the following day.
    • Jenny Sommers
       
      I like this idea of the "parking lot" board. Students do need to feel like asking questions is ok- this doesn't stifle them but lets class continue on track.
  • Students should be explicitly taught at a young age how to infer or make inferences.
  • a teacher may use bumper stickers or well-known slogans and have the class brainstorm the inferences that can be drawn from them.
    • Jenny Sommers
       
      I like this example.
