“…Part of the problem stems from very practical considerations: where to find these maps, when and how to explore them. It is possible that new refreshable display technology [10], or vibro-tactile display on commodity tablets [6], will alleviate some of this practical issues. Another major challenge is how to represent details at a wide range of levels.…”

Tactile maps of indoor spaces have great potential for supporting pre-journey spatial learning by blind travelers. Due to the limited resolution of tactile sensing, though, only a limited amount of spatial detail can be embossed in a map at a certain scale. We conducted a focus group with blind participants in order to obtain some insight on the perceived utility of using multiple maps at different spatial scales, and thus different level of detail, to represent the interior of a building.

“…While the creation of tactile graphics almost always necessitates creative interpretation given that tactile media requires highly generalized features, a potential benefit of using existing maps as source material is that the source maps largely circumscribe the range of features and their arrangement in the output map. But of course, the proposition of transcription is becoming more onerous as more maps become interactive (which would pose some interesting challenges regarding queryable features), and issues associated with rapid zooming in and out are impossible to address without refreshable braille display technology (see Leonardis et al, 2018, for an overview of recent developments on refreshable displays). However, this research could also offer potential avenues for developing 'rapid transcription' systems that could quickly produce tactile graphics in the absence of tactile graphics design tools.…”

Tactile cartography in the digital age: A review and research agenda

Spatial media for people who are blind or visually impaired (B/VI) have evolved considerably in the years following Chris Perkins’ review of tactile map research, especially due to the proliferation of Internet access, mobile computing, and GPS technology. Reviewing intervening research, I identify prevailing themes in cartographic data management, media production, map design, and map use. I then propose a research agenda that identifies four high-priority topics for investigation: research conducted by people who are B/VI, maps created by people who are B/VI, low-tech tactile mapping, and social dynamics of tactile map use and production.

“…Advancements in communication devices for the deafblind community have focused on Braille displays. Equipped with a refreshable 80 character screen, Braille displays allow users to access information from computers or other mainstream devices independently [7]. However, Braille displays are extremely expensive (limiting accessibility) and difficult to utilize for extended periods of time (more than 30 consecutive minutes), especially for those with multiple disabilities [8].…”

Currently, ∼1.5 million American deaf-blind individuals depend on the availability of interpreting services to communicate in their primary conversational language, tactile American Sign Language (ASL). In an effort to give the deafblind community access to a device that facilitates independent communication using tactile ASL, we developed TATUM (Tactile ASL Translational User Mechanism). TATUM employs 15 degrees of actuation in a hand-wrist system that is capable of signing the 26-letter ASL alphabet. Leveraging Interpres, an independent cloud-based service, all servo sequences that render desired fingerspelled letters and ASL words are stored in a web application programming interface (API). A validation study including both deaf and deaf-blind participants confirmed that the TATUM hand mimics a human hand both in size and feel. The current design of TATUM attained an average recognition rate of 94.7% in visual validation, indicative of the potential to support deaf and deaf-blind individuals in communicating via visual and tactile ASL.
