About HaptoRender

HaptoRender is planned to be a renderer that uses OSM data to create tactile maps for blind and visually impaired persons.

HaptoRender will have several advantages compared with commercial tactile maps:

Maps can be created for any village in the world - not only for city centers of interest for tourists
Maps can be created from current geodata, not only one edition in many years
Maps can vary, it is possible to create maps with additional contrasts for visually impaired persons
Maps are cheaper, because there will not be any license cost for the map data.
If one part of a map is obsolete, the part can be reproduced.

HaptoRender is planned to be based on Maperitive or Osmarender.

The HaptoRender project was started in April 2009 by Lulu-Ann.

Thanks to Bahnpirat and other members of Hannover Stammtisch for contribution.

News

2010-03-04 Lulu-Ann will speak about accessibility at the FOSSGIS 2010 in Osnabrück, Germany.
2009-07-12 Lulu-Ann held a lightning talk about accessibility at the State of the Map 2009 in Amsterdam, Netherlands.
First tactile map prototype out of copper was created by Bahnpirat. It was shown and touched at SOTM 2009 in Amsterdam.

Already produced maps

Reinhard-Niether-Krankenhaus in Wilhelmshaven, Germany

Map error: Invalid 'layer' value '%1'

This is the first known tactile map based on OSM data published on May 12, 2009. It is a copper sheet with the size of an DIN A4 paper sheet. This was shown (and touched) at the SOTM 2009 in [[]]Amsterdam. Contact Bahnpirat for more details on this.

HaptoRender Project Status

There are already two different ideas how to create tactile maps from OSM data.

Automated

Size and scale of map tiles are planned.
Needed file format is known (99%).
First map files are created. Improvement needed.
Prices are queried from one potential producer for prototype
Price for a production machine is known. Pretty expensive, maybe leasing?
Braille true type font with surely usable license is now available.
Map style for few objects is fixed.

Manual

First map is created!

General

Map style for tags of special interest for the blind are in work.
- Fixed are: tactile_paving=yes/no, information=tactile_map,school=blind
- In work are: traffic_signals:sound=yes/no, traffic_signals:vibration=yes/no
HaptoRenderPreCheck is not startet.
Displaying of license and OSM on product in braille writing and/or embossed printed letters is not clear.
...

Current to dos

We are looking for a braille .ttf (True Type Font) that complies with CC-BY-SA license. Who can help?
- For latin letters: I helped myself. I was sick of the non compatible licenses and made my own braille true type font. Download here.

Font needs to be replaced by braille. (OK for Latin, java library liblouis should do for all languages)
Rules shall be created.
An example legend exists.
Patterns/ textures need to be created for areas (forest, water etc.)
Symbols are needed for bus stops etc.
An additional sheet with the legend needs to be planned.
An legend must be created with all symbols
A street list needs to be generated for each created tactile map

General requirements

HaptoRender will not use abbreviated braille, but full braille writing (de:Blindenbasisschrift statt Blindenkurzschrift oder Blindenvollschrift).

What is in the map

A tactile map has a larger scale (1:1000) and shows less details than a visual map, but adds some tags that are of special interest for blind people.

Rendered in HaptoRender

This part has been moved to HaptoRender/Rendering_Rules

All features displayed on the visual map of features for the blind: blindmap.

Not in the map will be

Group	Tag	Value	Appearance	Remarks
`created_by=username`

Undecided

Group	Tag	Value	Appearance	Remarks

HaptoRenderPreCheck

The physical production of a tactile map usually causes costs. Before the HaptoRender can create a tactile map creation file of high quality, the desired area shall be checked for

completeness
common tagging mistakes
unknown tags
density of worthfull tags
tags that are known to cause troubles (to be defined)

Therefore a HaptoRenderPreCheck shall be created.

Ordering a map

If you want to be one of the first to order a tactile map from HaptoRender for yourself or as a present, please leave your Nickname and desired center coordinates here. Note: A tactile map tile from HaptoRender is planned to be for a 200m x 200m area, which is 20cm x 20cm in mapscale.

This is not an order, just a poll for interest!

Devices

These devices might be suitabel to create tactile maps from OSM:

for paper

Piaf Schwellkopierer

for plastic or rubber

Machines that can laser rubber stamps
Rapid prototyping machine with powder printing method
plastic extrusion rapid-prototyping machine (e.g. RepRap, UP! 3d Printer)

for plastic, wood or metal

CNC machine (different file format!)
waterjet (takes dxf gnerally)

for stone

Waterjet

Side effects: Tattoos

You could use a HaptoRender Map for making a temporary tattoo. Don't forget to request a mirrored with printed letters instead of braille writing map!
