New technologies open new chances for blind people
Hello, I am Per Busch from Germany and I want to inform you about the unique open source project Loadstone-GPS. Please excuse my english, it's not my mother tongue.

The following could be interesting for the Corporate Responsibility and the public relations of the Open Handset Alliance and all the other companies & organisations with enough goodwill, vision and imagination.

The main programmer of the Loadstone-GPS software, Shawn Kirkpatrick, and all the members of the Loadstone-team are blind and developers of a free and open source navigation software for blind pedestrians like me. At present, this program runs on Nokia S60 Symbian devices and is a great solution for increasing the mobility of blind persons, thereby making their lives much easier and more independent. Since for large rural regions of our world or developing or newly industrializing countries nearly no exactly map data is available in common map databases, the Loadstone software provides users with the option to create, store, and share their own navigation waypoints with others. Although satellite navigation can not replace a white cane or guide dog, it complement perfectly.

There is a growing community of Loadstone users, testers and developers. This kind of self-help and collaboration on a global scale is a very new approach - especially given the fact that the software is free and open source. At the moment a lot of blind people around the world are using Nokia cell phones because there are two professional - albeit expensive - screen reader software products for the S60  Symbian platform; Talks from Nuance Communications and Mobile Speak from Code Factory,  which make these devices accessible by output of synthetic speech and also allow the use of third party software such as Loadstone, web browser, audio player or DAISY book reader.

It would be desirable to have a screen reader software for the new Android platform too; the best solution would be an open source development such that blind people from the developing regions of our world have access to it as well, perhaps including the offer of an affordable, accessible and optimized mobile hardware with components from mass market. This device would need to have good tactile keys and a high-quality loudspeaker and should be protected against moisture and dust. Although a display would not really be necessary, there should be a connection port for a screen. An optimized receiver of satellite signals for pedestrian use, an electronic compass and perhaps an accelerometer or a gyroscope could be offered in a wearable Bluetooth box. Additional hardware like a PC keyboard, a headset, a small remote control, a portable Braille display, loudspeaker or a large display for people with low vision could also be connected via cable or Bluetooth. A built in camera would enable light detection, color recognition, optical character recognition (OCR) and is useful in situations when seeing help from distance is needed. Though a camera might be too expensive for the basic device it could be offered as an accessory. Built in RFID technology for several purposes is imaginable as well But it's important to minimize the production costs of the main units to keep them affordable.

"Through Android, developers, wireless operators and handset manufacturers will be better positioned to bring to market innovative new products faster and at a much lower cost. The end result will be an unprecedented mobile platform that will enable wireless operators and manufacturers to give their customers better, more personal and more flexible mobile experiences." (from the Open Handset Alliance site)

Nokia, Google and other companies from the mobile tech sector could help to quicken the evolution of accessible satellite navigation solutions and mobile internet access for blind and visually impaired people around the world. Some of the members of the Open Handset Alliance perhaps have the knowledge and goodwill to program a free & open source Android Screen Reader software and an Android application with the Loadstone functionality or providing support/resources for that. Google's $10 Million Android Developer Challenge could also be an incentive for other developing teams. The Loadstone community will surely give all the needed information about user wishes and certainly many suggestions as well.

A lot of the 37 million blind and 124 million visually impaired persons from all over the world will love the doer & companys for that! Especially the 1.4 million blind children below the age of 15.

"Speaking" mobile technology is a great chance for them to obtain access to satellite navigation and other useful applications, web based applications, communication, information, education, learning and location based services. this will open new opportunities for the job market and for participation in social networks and in society, especially for those from countries, where access to fixed phones or landline internet is rarely available but cellular radio networks are common. 

The intentions of the OLPC-project (one laptop per child) could perhaps be a kind of model for this idea and the Android platform could open the door for the blind & visually impaired people. Then they would be more independent of trading policies and the mostly expensive prices of the few global vendors of assistive technology.

Loadstone GPS
Here is what the Loadstone team wrote me a few months ago, when I asked them for details about their story:

"The Loadstone project was started in 2004 by Monty Lilburn and Shawn Kirkpatrick, both blind. Monty, Canadian and recently moved to Glasgow, Scotland, explains:

"Ever since first finding out about the GPS satellite network in the early 90's I knew this was something that was going to in time complement my mobility skills.  It was just a case of waiting for the technology to be available.  Of course the late 90's and early 2000's brought us GPS for the blind from the Sendaro group, then Visuaide and Humanware/pulse-data came out with solutions.  The problem with all of these solutions was (and still is) cost.

In 2004 I purchased my first speech-enabled mobile phone (Nokia 6600 with Talks) and immediately saw the potential of having a portable device which could interface with a bluetooth GPS receiver. I communicated this idea with my good friend and excellent programmer Shawn who was back in Vancouver."

After two years of development a navigation program existed that was able to inform the user about marked points in the nearby environment. Using the joystick on the mobile phone the environment could be scanned and provided sufficient information to serve as a navigational aid. In May 2006 the duo decided to put the program at the disposal of other blind and visually impaired people with a need for a cheap, lightweight device that could inform them about their whereabouts. A good friend came up with the name Loadstone, a magnetic iron ore that had served as a compassneedle around 1000 AD.

In the summer of 2006 Shane Wegner and Rob Melchers joined the project, Shane as the webmaster of the Point Share Exchange, a web site that serves as the central deposit for navigational points and Rob from Amsterdam as the writer of the documentation and developer of the online-tools that compliment the use of the Loadstone program. Shane and Rob are also blind and have, like Monty and Shawn, long-time experience in programming and web development.

Where the initial development costs have been carried by Monty and Shawn, the future of the project relies on donations and eventually sponsorship.

Loadstone is free software under the GPL and the Loadstone team has the intention to keep it that way. Next to the further development of the program the most important thing is 'getting the word out', so that blind and visually impaired people from all over the world have access to an affordable and portable means of orientation."

What you could do for the Loadstone project?

 * Symbian programmers could download the Loadstone source code, become familiar with it and after that they could make concrete suggestions & contributions for improvements. There is a large to do list.
 * What the Loadstone team would need most is a Symbian publisher id and the financial support to maintain this. This would enable them to sign the program and hence offer the user an easy to install package. Currently all users of modern devices (Symbian 3rd Edition) first have to solve the problems of the inaccessible and difficult signing process at WWW.Symbiansigned before they can install Loadstone.
 * A sponsor could invest in licenses for map data from companies like Navteq or Tele Atlas. The licenses must allow for the distribution of the data, at least to blind and visually impaired users. Any form of data is useful and can be converted to the Loadstone format. If any technical information about this data is needed the Loadstone team will be glad to provide it.
 * You could loan test phones with built in GPS receiver to the Loadstone team (e.g. Nokia N95 or 6110 Navigator) so they can develop a Loadstone version for this devices as well.
 * You could help to translate the software user interface, documentation and release notes into other languages. Maybe this could happen in a free & hosted BlindWiki or LoadstoneWiki. You could help to find volunteers and promoters for that work as well. Many blind people worldwide are not able to understand English and so they can't use Loadstone.
 * You could help to convince vendors of Bluetooth GPS receivers like Holux, Royaltec or their supplier SIRF. Blind people are pedestrians and need optimized receivers with best accuracy at low or no speed. Therefore the firmware of standard products must be modified and a waterproof receiver box which could be fixed to clothes or e.g. the white cane would be fine too. Such a receiver would be ideal for blind users of commercial assestive GPS solutions and seeing customers with special needs as well.
 * You could help to get the software integrated into mobility training programs by blindness institutions and guidedog schools. Promotion in that direction would be appreciated.
 * Qualified programmers could try to port Loadstone to the Windows Mobile platform.
 * There are many other imaginable ways to help. Please ask the Loadstone team.

Android Screen Reader
The open source project OpenIntents has perhaps already found interest in developing a screen reader for the Android platform. OpenIntents is a common effort to define and implement standard interfaces such that Android applications can work more closely together. Please ask Peli. Android should have an Accessibility API for assistive tools, thereby making applications accessible for all users. Android should have a free speech engine (tts) as well. L1GHTM4N already tries to port the FreeTTS code to Android. See also:

Examples: Fire Vox is an open source talking browser extension for the Firefox web browser, FreeTTS is a Java speech synthesizer

NVDA is an open source Screen Reader for Windows, Orca is an open source Screen Reader for Linux
