tactile symbol designer is inspired by the Project Core Universal Core tactile symbols but attempts to go further to provide <a href=\"https:\/\/volksswitch.org\/index.php\/volks-devices\/bliss-tactile-symbols\/how-project-core-tactile-symbols-fall-short\/\">flexibility, extensibility, and simplicity<\/a>.<\/p>\n<h4>Graphic Alternative<\/h4>\n<p>We wondered whether there was a way to provide relevant graphics, make them easy to print, and sturdy at the same time.\u00a0 It turns out that Project Core focuses primarily on a set of <a href=\"http:\/\/www.project-core.com\/36-location\/\">visual graphics<\/a> that it makes freely available to individuals who would like to use their system.<\/p>\n<p>The visual PCS symbol that Project Core uses to represent &#8220;Get&#8221; looks like this:<\/p>\n<p><a href=\"https:\/\/i0.wp.com\/volksswitch.org\/wp-content\/uploads\/2020\/12\/get.png?ssl=1\"><img

whether this image could be turned into a raised graphic that could be tactilely explored and interpreted by someone who&#8217;s blind or visually impaired.<\/p>\n<p>Our approach is to covert the graphic into an SVG file and then create 3D version that can be added to a tactile symbol:<\/p>\n<p><a

\/><\/a><\/p>\n<p>We&#8217;ve taken the 36 Universal Core graphics and used them as a basis for our symbols.<\/p>\n<p>An added advantage to taking this approach is that it makes it easy to extend the current set of 36 symbols to cover new concepts.\u00a0 All you need is a representative image in SVG format.\u00a0 Need a symbol that represents the concept &#8220;butterfly&#8221;?\u00a0 You just need to find an SVG image of a butterfly:<\/p>\n<p><a href=\"https:\/\/i0.wp.com\/volksswitch.org\/wp-content\/uploads\/2020\/12\/butterfly-svg-to-symbol.png?ssl=1\"><img data-recalc-dims=\"1\"

box followed by &#8220;.svg&#8221;.<\/p>\n<h6>Specifying the graphic&#8217;s aspect ratio<\/h6>\n<p>The designer doesn&#8217;t know much about the graphic but it will try to size it to the approximate size of the symbol.\u00a0 One thing it doesn&#8217;t know is the graphic&#8217;s aspect ratio.\u00a0 That&#8217;s the relationship between the height and width of the graphic.\u00a0 Is it wider than it is tall or taller than it is wide?\u00a0 The designer needs some help from you to get that right.\u00a0 \u00a0To determine the aspect ratio of your graphic, hold your mouse pointer over the graphic file.\u00a0 A tool-tip will appear that shows the pixel size of the graphic:<\/p>\n<p><a href=\"https:\/\/i0.wp.com\/volksswitch.org\/wp-content\/uploads\/2020\/12\/image-width-and-height-in-pixels.png?ssl=1\"><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-3620\" src=\"https:\/\/i0.wp.com\/volksswitch.org\/wp-content\/uploads\/2020\/12\/image-width-and-height-in-pixels.png?resize=283%2C212&#038;ssl=1\" alt=\"Mouse over an image file shows the pixel size of the image.\" width=\"283\" height=\"212\" srcset=\"https:\/\/i0.wp.com\/volksswitch.org\/wp-content\/uploads\/2020\/12\/image-width-and-height-in-pixels.png?w=380&amp;ssl=1 380w, https:\/\/i0.wp.com\/volksswitch.org\/wp-content\/uploads\/2020\/12\/image-width-and-height-in-pixels.png?resize=300%2C225&amp;ssl=1 300w\" sizes=\"auto, (max-width: 283px) 100vw, 283px\" \/><\/a>Above, the &#8220;butterfly image.png&#8221; file is 310 pixels wide and 179 pixels high.

center;\">(179 \/ 310) * 100 = 57.7<\/p>\n<p>To get the image to look right, enter 58 as the &#8220;aspect ratio&#8221;.\u00a0 Unfortunately, Windows doesn&#8217;t know much about SVG files so if you hold your mouse cursor over an SVG file you won&#8217;t get any useful information about the aspect ratio of the graphic in SVG form.\u00a0 Instead you&#8217;ll need to experiment with different aspect ratio values until the graphic looks right to you.<\/p>\n<h6>Graphic placement<\/h6>\n<p>Next you&#8217;ll work to get the graphic in the best place on your symbol.\u00a0 Experiment with different values of graphic size, and horizontal and vertical location until the graphic is as large as possible but still fits on the face of the symbol.\u00a0 Nothing else is going to go on the face of the symbol so you can make the symbol as large as possible.\u00a0 [One complication may come along if you put a hole through the symbol from front to back.\u00a0 More on that topic below.]<\/p>\n<p>This might be a good time for you to save your work by creating a new &#8220;Preset&#8221;.\u00a0 You can read more about working with presets below.<\/p>\n<h6>Graphic Height<\/h6>\n<p>You can set the amount that the graphic rises up off the surface of the symbol from 1 mm to 5 mm.\u00a0 The value you choose will depend on what value you think will be most effective
