A Multi-scale Embossed Map Authoring Tool for Indoor Environments

Area of Science:

• Geographic Information Science
• Human-Computer Interaction
• Assistive Technology

Background:

• Creating accessible indoor navigation aids remains a challenge.
• Existing tactile maps often lack multi-scale representation or on-demand generation capabilities.
• 3D scanning technology offers new possibilities for detailed environmental mapping.

Purpose of the Study:

• To introduce a novel tool, the multi-scale embossed map authoring tool (M-EMAT), for generating customized tactile maps of indoor environments.
• To enable the on-demand production of tactile maps at various spatial scales.
• To provide an easy-to-use solution for creating accurate tactile representations of complex building interiors.

Main Methods:

• Utilizing building structural layouts and 3D-scanned interior data as input.
• Developing an authoring tool (M-EMAT) capable of rendering tactile maps at multiple spatial scales.
• Implementing algorithms for accurate geometric representation and embossing.

Main Results:

• Successful generation of multi-scale tactile maps for indoor environments.
• Demonstrated ease of use and accuracy, even for complex building structures.
• On-demand map production tailored to specific user needs (building overview, specific area, room interior).

Conclusions:

• M-EMAT provides a versatile and accurate solution for creating customized tactile maps.
• The tool enhances accessibility and navigation within indoor environments.
• On-demand, multi-scale tactile map generation is feasible and beneficial for complex spaces.
