Various examples described herein are directed to systems, methods, and computer-readable medium for providing a tactile response. A document that includes visual data is received. Change data for the visual data that indicates changes in data values of the visual data from a previous time is received. The visual data is rendered. An indication that a section of the document is selected is received. The section includes a first visual data. A change of the first visual data is determined front the change data. A tactile response unit is controlled to provide a tactile response based on the change of the first visual data.

Disclosed in some examples are methods, systems, devices, and machine-readable mediums which provide a wearable device, such as a smart ring, that provides feedback to guide users in performing physical tasks. Tasks may include tasks associated with an application executing on a mobile device of the user.

A haptic system includes a haptic device and a control device. A sensor of the haptic device detects contact of a finger of a user who grips a casing, a determination unit of the control device determines whether sensor information on a contact position of the finger detected by the sensor of the haptic device matches preset reference position information, and an instruction unit sends a notification unit a notification instruction in at least one of cases where the sensor information does not match the reference position information and where the sensor information matches the reference position information. On accepting the notification instruction, the notification unit of the haptic device notifies the user of an indication indicating that the contact position of the finger is shifted or an indication indicating that the contact position of the finger matches the reference position.

A haptic actuator may include a housing that includes first and second shells coupled together. The first shell may include a first body and first terminals extending outwardly therefrom. The second shell may include a second body and second terminals extending outwardly therefrom with each of the second terminals being secured with a respective one of the first terminals defining pairs of first and second secured-together terminals. The haptic actuator may also include at least one coil carried by the housing and a field member movable within the housing responsive to the at least one coil. A respective flexure may be between adjacent end portions of the housing and the field member.

A controller for an implantable blood pump including processing circuitry in communication with the implantable blood pump and configured to generate at least one preventative alert.

An actuator housing intended to provide haptic feedback in a vehicle includes a container having a recess configured to accommodate an oscillating actuator and an insertion opening that opens into the recess, and a cover configured to at least partially close the insertion opening of the container. The container and the cover being are mounted so as to be able to move in translation relative to each other and configured such that, when the oscillating actuator is accommodated in the recess the oscillation of the oscillating actuator causes the cover to move in translation relative to the container, generating haptic vibration in a direction of movement.
