Why is Next Generation Visual Aid Important?
  • Millions of people in America have severe vision
  • According to the Lighthouse National Survey on
    Vision Loss, in 2010 there will be an estimated
    8.3 million Americans, ages 65 and over who have
    some type of visual impairment. This number is
    expected to grow quickly from 2010 to 2030 to a
    total of 14.8 million elderly Americans with a
    visual impairment, 7.7 million of which will have
    a severe impairment.
  • According to the National Advisory Eye Council,
    the economic impact of visual disorders and
    disabilities was approximately 14.2 billion per
    year in 1981. By 1995 this figure was estimated
    to have risen to more than 38.4 billion per
  • We are changing peoples lives for the better.
    We are giving them hope. We are CREATING ABILITY
  • Proverbs says Without Vision the people perish
    Proverbs 2918

Why is Next Generation Visual Aid Important?
  • How much is it worth to be able to see faces?
  • How much is it worth to be able to read stories
    to your kids?
  • Whats the price of a persons self-esteem?
  • The reason, above all else, is that we are
    helping PEOPLE

Goal for Advanced Visual Aid
  • To create Ability from Disability for those with
    visual impairment
  • Address both the needs of low vision patients AND
    those with situational visual impairments
  • Target developments to both the wide consumer
    market AND the disability market
  • Mass consumer market will attract partners,
    finance research and lower the cost of what is

Concept for Low Vision Aid
Electronics Wireless communications
Image processing, camera control wireless
How Do We Achieve This Goal?
  • The consumer marketplace is driving the
    developments we need
  • Smaller and more powerful ultra portable
    computers (computer gaming and laptops)
  • Increasing integration of functionality into
    portable devices (cell phone, PDA etc)
  • Computer, cell phone, Personal Digital Assistants
    (PDAs), Global Positioning Satellite (GPS)
  • Wireless communication and smart networks
  • Improved display technologies with better
    resolution, higher contrast and lower power
    consumption (portable computing)
  • Smaller batteries with higher energy density
    (laptops, cell phones)
  • Smaller, lighter optics and cameras (digital
    cameras, camcorders)
  • We ride the wave of these technologies and
    develop only what we need to.

Approaching the One-Chip Device
Near-term Developments (
  • Today it takes 1 chip for microcontrollers in
    small devices, GPS and radio (see figure from
    left to right - a microcontroller chip, GPS
    receiver chip, OOK radio module)

    Trends in Semiconductor Industry
    Near-term Developments (
  • Computer chips
  • Chip makers are now moving from a 90 nanometer
    feature size to a 65 nanometer feature size.
    This will reduce chip sizes and power
  • Intel has just released a new chip set and
    reference design which enables smaller PDAs
  • Processors for mobile computing continue to
    become faster and have lower power consumption

  • 22
    Trends in Cell Phone Processor Performance
    Near-term Developments (
  • Intel just introduced a MEMS chip that integrates
    passive components onto a single chip, saving 66
    in size
  • Hermon, Intel's next-generation integrated
    cellular processor will integrate the Bulverde
    application processor formally launched last week
    as well as a baseband processor and flash.
  • The Hermon chip will bring Pentium-class
    performance to cell phones and could help reduce
    component count which today hovers at about 200
    parts in phones with 286-class performance
  • Cell phones can now read RFID tags. Nokia
    recently introduced a Mobile RFID kit for its
    5140 GSM phones. (Check out,
    DocFinder 1729, for details).
  • Cell phones are adding the processing power and
    capabilities and already have internet access.
    They already have a huge user base and are
    produced in the millions.

    Trends in PCs
    Near-term Developments (
  • Developments in PCs
  • AMD's HyperTransport allows a computer's key
    components to communicate with each other at
    speeds of up to 50 times faster than the PCI bus
    currently used in most PCs
  • PCI Express - faster and simpler version of the
    PCI bus that promises to reduce the size and cost
    of both plug-in cards and motherboards
  • Serial ATA - high-speed storage interface that
    cuts down on the cabling within PCs
  • Serial-Attached SCSI - speed-scalable and less
    power-hungry version of the familiar SCSI storage
    device interface that also allows for physically
    smaller drives
  • Express-Card - new PC expansion card standard,
    based on PCI Express, replaces older PCMCIA cards
    with smaller, faster and cheaper plug-in modules
  • Transition from 32-bit to 64-bit technology

    Engineering The ProductChallenge Transparent
    • This is one of our big challenges
    • Involves
    • Ease of use
    • Intuitiveness
    • Enhance senses we use
    • Many low vision patients are elderly. Many in
      the current generation of elderly people suffer
      from Technophobia
    • Clinical trials and real-world feedback are

    Engineering The ProductChallenge Operational
    • What kind of resistance does the device have
      against its use?
    • Involves
    • Ease of setup time and effort required before
      initial use
    • Interactive complexity how difficult is device
      to interact with (controls etc)
    • Obtrusiveness of device
    • When not in use
    • When in use does it make you look like a geek?
    • Price to the end user
    • Many low vision patients are elderly with fixed
    • 4,000 is too much for many of them
