A wearable device determines an objective based on analyzing a voice of a user, where the wearable device comprises one or more wearable sensors and one or more wearable actuators. The wearable device identifies objects by the one or more wearable sensors. The wearable device determines an action based on the objective and the identified objects and guides the user to achieve and objective by the one or more wearable actuators.

A variety of haptic improvements useful in mobile devices are detailed. In one, a smartphone captures image data from a physical object, and discerns an object identifier from the imagery (e.g., using watermark, barcode, or fingerprint techniques). This identifier is sent to a remote data structure, which returns data defining a distinct haptic signature associated with that object. This smartphone then renders this haptic signal to the user. (Related embodiments identify the object using other means, such as location, or NFC chip.) In another arrangement, haptic feedback signals social network information about a product or place (e.g., the user's social network friends “Like” a particular brand of beverage). In yet another arrangement, the experience of watching a movie on a television screen is augmented by tactile effects issued by a tablet computer on the viewer's lap. In still another arrangement, commercial vendors bid for rights to employ different ones of a library of haptic signals on one or more users' smartphones, e.g., to alert such user(s) to their products/services. A great variety of other features and arrangements are also detailed.

Methods, apparatus, systems, computing devices, computing entities, and/or the like for identifying one or more visual impairments of a user, mapping the visual impairments to one or more accessibility solutions, (e.g., program code entries) and dynamically modifying a display presentation based at least in part on the identified accessibility solutions.

Adaptive Control Driven System/ACDS 99, supports visual enhancement, mitigation of challenges and with basic image modification algorithms and any known hardware from contact lenses to IOLs to AR hardware glasses, and enables users to enhance vision with user interface based on a series of adjustments that are applied to move, modify, or reshape image sets and components with full advantage of the remaining useful retinal area, thus addressing aspects of visual challenges heretofore inaccessible by devices which learn needed adjustments.

A tactile pin actuator comprises a tactile pin assembly that includes a tactile pin and a recess that has a first screw thread formed thereon. A stop assembly is rigidly coupled relative to the tactile pin actuator. A lead screw attached to a shaft is positioned in the recess and is mechanically engaged with the first screw thread. A projection extends axially from the shaft. Rotation of the shaft in a first rotational direction relative to the tactile pin assembly causes the tactile pin assembly to move linearly in a first linear direction away from the shaft. Rotation of the shaft in the first rotational direction ceases when the projection comes into contact with the stop assembly. Rotation of the shaft in a second rotational direction causes the tactile pin assembly to move linearly in a second direction toward the shaft. Rotation of the shaft in the second direction ceases when the projection comes into contact with the stop assembly.

The technology disclosed herein includes a navigation system for a visually impaired person to navigate a public restroom. The navigation system may include a plurality of fixtures, a plurality of installations, wherein each installation is electronically connected to a fixture, and an electronic device, the electronic device configured to receive auditory or tactile signals from each installation and produce a signal indicative of a fixture location. The plurality of fixtures may include a toilet, a urinal, a sink, a soap dispenser, and a hand drying apparatus.

A system and method for transmission of a signal for a powered assistive device has a sensor node with a wireless transmitter adapted for digitally transmitting a transmitted signal, the sensor node adapted for receiving and monitoring a sensor signal from a sensor attached to a user, and a master node with a controller and a wireless receiver for receiving the transmitted signal from the wireless transmitter. The master node processes the transmitted signal and communicates a control signal to the powered assistive device. The wireless transmitter transmits the transmitted signal at a first rate when the wireless transmitter adapted to transmit the transmitted signal at a first rate when the sensor signal is indicative of the rest state and to transmit the transmitted signal at a second rate when the sensor signal is indicative of the active state, the second rate being greater than the first rate.

An information processing device calculates an occupancy rate of a pedestrian crossing in an image obtained by capturing an image of a traveling direction of a target person, determines a crossing status of the target person for the pedestrian crossing based on the calculated occupancy rate, and generates support information for supporting the target person crossing the pedestrian crossing based on the crossing status.

An apparatus to capture and display an image of an object includes a frame, at least one optical sensor for capturing the image of the object, means for moving the frame relative to a surface of the object in a first direction, and means for moving the optical sensor relative to the frame in a second direction.

Data representative of a physical feature of a morphologic subject is received in connection with a procedure to be carried out with respect to the morphologic subject. A view of the morphologic subject overlaid by a virtual image of the physical feature is rendered for a practitioner of the procedure, including generating the virtual image of the physical feature based on the representative data, and rendering the virtual image of the physical feature within the view in accordance with one or more reference points on the morphologic subject such that the virtual image enables in-situ visualization of the physical feature with respect to the morphologic subject.
