Why is next generation visual aid important l.jpg
Why is Next Generation Visual Aid Important?

  • Millions of people in America have severe vision loss.

  • 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 year.

  • We are changing people’s lives for the better. We are giving them hope. We are CREATING ABILITY

  • Proverbs says: “Without Vision the people perish” Proverbs 29:18

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?

  • What’s the price of a person’s self-esteem?

  • The reason, above all else, is that we are helping PEOPLE


Goal for advanced visual aid l.jpg
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 developed

How do we achieve this goal l.jpg
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)

Trends in semiconductor industry l.jpg

Near-term Developments (<1 year to market)

Trends in Semiconductor Industry

  • 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 consumption.

    • 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


Trends in cell phone processor performance l.jpg

Near-term Developments (<1 year to market)

Trends in Cell Phone Processor Performance

  • 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 www.nwfusion.com, 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 l.jpg

Near-term Developments (<1 year to market)

Trends in PCs

  • 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 product challenge transparent use l.jpg
Engineering The ProductChallenge: Transparent Use

  • 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 crucial


Engineering the product challenge operational inertia l.jpg
Engineering The ProductChallenge: Operational Inertia

  • 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 income

      • $4,000 is too much for many of them
