A software application and system may be configured to enable a smartphone or other device to be used by a visually impaired person to receive voice navigation guidance during a directed exploration of an area. Directed exploration uses combinations of location data, directional data, and orientation data from the configured device to determine a direction that user wishes to explore, and only providing narrated results for streets, businesses, and other points of interest in that direction. The system may also utilize sets of wireless indicators positioned within indoor areas to provide accurate positioning to particular locations and floors within buildings.

A method and apparatus for recognizing walking information using multiple magnetic sensors are provided. The method for recognizing walking information comprises generating a magnetic sensing signal from magnetic paint applied to a ground, generating a frequency-converted signal using the magnetic sensing signal, and generating walking information using the frequency-converted signal.

The invention relates to a product controlled with waterproof piezo crystals developed to control, through piezo crystals, the signaling system triggered before, during and after the crossing by pedestrians at signaled traffic intersections, wherein the product is highly durable and long-lasting, and facilitates use of signaled intersections by visually or hearing impaired and other pedestrians, and activates the signaling system, without the need to press any button, by detecting the pedestrians who stepped and applied pressure thereupon, thereby eliminating the risk of disease transmission.

A disaster safety smart shelter is a shelter installed outdoors and includes: a shelter housing including a plurality of side wall parts, a ceiling part shielding upper portions of the plurality of side wall parts, a waiting space formed therein and an opening and shutting door which is formed through at least a portion of the side wall parts to allow access to the waiting space; a ventilation module including an air discharge port provided through the ceiling part to discharge air inside the waiting space to the outside and an air suction port for supplying air from the outside to the waiting space; an information guidance terminal module provided to the exposed to the inside of the waiting space and displaying a plurality of pieces of information to a user; and a power supply module provided on the ceiling part to supply power to each part.

A virtual reality system is described herein. The virtual reality system includes a cane controller and a computing system. The cane controller comprises a rod, a sensor, and a brake mechanism, wherein the sensor is configured to generate a signal that is indicative of position, direction of movement, and velocity of the rod, and wherein the brake mechanism is configured to apply a force to the rod. The computing system receives the signal, computes a position, direction of movement, and velocity of a virtual rod in a virtual space, and outputs a control signal to the brake mechanism based upon such computation. The brake mechanism applies the force to the rod in a direction and with a magnitude indicated in the control signal, thereby preventing the user from causing the virtual rod to penetrate a virtual barrier in the virtual space.

Detectable warning areas (DWAs) and methods of forming the same. A dome-forming material can be mixed with a catalyst to form a mixture, which can then be poured into a dome-shaped cavity of a die-cast mold or a reusable mat template with a grommet. A peg may be inserted into the mixture. The mixture may be allowed catalyze and harden.

A tactile tile assembly includes a base having a plate section, a rim projecting up from the plate section, and a plurality of embedment anchors on the base. A tactile tile is adapted to fit into or onto the base. Fasteners extending through the tactile tile attach it to the base. The top of the rim may be substantially co-planar with a top surface projections on the tactile tile. The embedment anchors may be provided in a plane of the plate section and be bent to a position perpendicular to the plate section for embedment into a pavement material. The base has attachment elements for attaching the tile assembly to an adjoining tile assembly. Two or more tile assemblies are attached together to provide a tile assembly combination of a desired size and shape. The tile assembly combination is then installed in the paving material.

The present invention relates to tactile warning panels, and in particular to tactile warning panels that are designed and built with multi-function/multipurpose capabilities that serve the visually impaired and enable the deployment of smart city technology by integrating tactile warning systems and subsurface enclosures that can withstand pressures of five (5) tons up to and exceeding sixty (60) tons and incorporate small cells, beacons, sensors, Fog Computing, electric energy generation, rechargeable power supplies, wireless M2M communication and a plethora of other smart city technologies.

Detectable warning areas (DWAs) and methods of forming the same are provided. A dome-forming material can be mixed with a catalyst to form a mixture, which can then be poured into a dome-shaped cavity of a die-cast mold. A peg may be inserted into the mixture in the dome-shaped cavity of the die-cast mold. The mixture may be allowed catalyze and harden in the dome-shaped cavity of the die-cast mold, then a molded dome may be removed from the dome-shaped cavity of the die-cast mold. A portion of the molded dome such as the peg may be inserted into a hole in a prepared substrate. The dome may also be prepared by grinding an outer top surface with a drilling attachment. The dome may instead be formed with the use of an insert and a mat template.

Aspects of the subject disclosure may include, for example, a process by which first data is received from a mobile device regarding first objects detected by the mobile device in an area, the first data having been collected by the mobile device at a number of first collection points while moving along a first path from an initial position in the area to a boundary of the area. The first data is aggregated with second data previously collected regarding second objects in the area, the second data having been collected at a number of second collection points along a second path different from the first path. The second data includes a position indicator for each of the second objects indexed by the initial position. A map of the area is generated based on the aggregating and the map is transmitted to the mobile device. Other embodiments are disclosed.
