  • Great Article on Touch Pads

    The square Tenji block system was invented in Japan by Seiichi Miyake in 1965 and first used in Okayama City in 1967. The oblong raised pattern indicate places, and in what direction, it is safe to walk confidently. The “warning” blocks with the round raised dots indicate edges, corners or other places where greater care or caution is required. The tactile cues developed for these unique blocks help everyone stay clear of train platform edges, crosswalk dropoffs, and other related hazzards. Sighted or not, it’s really quite amazing how well these blocks work. You can easily discern the difference without looking.

  • What Are Truncated Domes?

    Truncated domes have a unique design that can be detected underfoot and with a cane, and other surfaces are not considered ADA equivalent and therefore do not comply with the ADA requirements.

  • What Are Detectable Warnings?

    Detectable warnings, a distinctive surface pattern of domes detectable by cane or underfoot, are used to alert people with vision impairments of their approach to streets and hazardous drop-offs. The ADA Accessibility Guidelines (ADAAG) require these warnings on the surface of curb ramps, which remove a tactile cue otherwise provided by curb faces, and at other areas where pedestrian ways blend with vehicular ways. They are also required along the edges of boarding platforms in transit facilities and the perimeter of reflecting pools.
