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• If one part of a map is obsolete, the part can be reproduced.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

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

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

Primitive: Node

Group	Tag	Value	Appearance	Remarks
Traffic signals	highway=*	traffic_signals	Proposed: Two holes in a rectangle like the lights of a pedestrian traffic signal (tactile test necessary)
Public Transportation	highway=bus_stop with and without tactile paving	Proposed: Circle on street layer, half on the street, half next to it. Braille abbreviation for name of bus stop (-> Legend)	If tactile_paving=yes then with an embossed circle around on empty space level.
Public Transportation	railway=halt with and without tactile paving	to be definded
POI	amenity=(only most important)	to be defined
Tactile Maps	tourism=information + information=tactile_map	to be defined

Primitive: Way

Group	Tag	Value	Appearance	Remarks
Streets	highway=residential		Deeper than empty space layer. Width = 7mm	If additional lanes=* ist given, 3.5mm per lane. If additional width=* is given, devide value by scale 1:1000.
Streets	highway=tertiary		Deeper than empty space layer. Width = 8mm	If additional lanes=* ist given, 3.5mm per lane. If additional width=* is given, devide value by scale 1:1000.
Streets	highway=secondary		Deeper than empty space layer. Width = 9mm	If additional lanes=* ist given, 3.5mm per lane. If additional width=* is given, devide value by scale 1:1000.
Streets	highway=primary		Deeper than empty space layer. Width = 10mm	If additional lanes=* ist given, 3.5mm per lane. If additional width=* is given, devide value by scale 1:1000.
Streets	highway=service		Deeper than empty space layer. Width = 4.5mm	If additional lanes=* ist given, 3.5mm per lane. If additional width=* is given, devide value by scale 1:1000.
Streets	highway=unclassified	(same as residential)	Deeper than empty space layer. Width = 7mm	If additional lanes=* ist given, 3.5mm per lane. If additional width=* is given, devide value by scale 1:1000.
Railways	railway=track	Embossed dashed line	Width = 3.5 mm	Maybe background layer higher than empty space?

Primitive: Area

Group	Tag, Value	Appearance	Attributes	Remarks
Street: Pedestrian area	highway=pedestrian	On the same layer as streets (deep, -1)	Name: Center name in area in Braille	Texture?
Lake: Landuse = Water	landuse=water	On the same layer as empty space (even, 0)	Name: Center name on textureless back in Braille	Texture: parallel sinus waves of 1 mm width, from west to east

Primitive: Relation

Group	Tag	Value	Appearance	Remarks
Routes	Relation Type=Route	Route=Bus

Others

Object	Tag	Appearance	Remarks
"HaptoRender"
Name of the map (name of the city)
Tile number			to sort the tiles of a tile set
Copyright and License	none	"Copyright by (my name, your name) and OpenStreetMap contributors, license cc-by-sa" in Braille and embossed printed latin letters (Arial?)	Maybe cc-by-sa in oval as in the original label?
Compass Rose	(none!)	Wide arrow pointing north (=up) with Braille letter for "n" in the arrowhead (maybe "s" in the end)	Not on each tile?
Legend	Name-Tag of different objects (bus_stop)	Not in the map but on extra paper. left column: abbreviation like on the map, right column: name
Braille writing	Different naming tags	Size is fix, height is 6.5mm, TTF: Braille Schirftsatz Blista Marburg	How to write in Braille: (German book for sightes persons) Das System der deutschen Blindenschrift We are going to use Basischrift(=Common letter combinations have their own Braille representation) (nicht Vollschrift(=each black letter is one Braille letter)), as street names are not well presented by Kurzschrift (=Braille-Stenographie).
Coordinates	(Base coordinate)	To identify the position of single tiles in a set of tiles	Center coordinates, decimal, scale (?)
Scale	(no tag)	Box with a streight line and markers on it, and the value and unit, Braille (like this: +-----------+ 50 m )	Not on each tile? Near Compass rose?
Puzzle connector hole	(no tag)	On each side of the square tile, on the back, there shall be a hole in the base layer, shaped like a circle where 20% of the circle area are cut off at the edge.	Different shapes for NWES? How deep?
Puzzle connector pieces	(no tag)	Need to fit into the puzzle connector holes.	How thick?

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!

Thanks to http://www.caretec.at for sending some special paper for the Piaf Schwellkopierer.

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!
