One embodiment relates to a method for creating a fast vanishing light scattering surface/volume to which an image is projected. The method includes: creating two portions of atomized particles of a given particle size that does not allow an incident light having a visible spectrum from being scattered, reflected and/or dissipated; and ejecting these two portions of the atomized particles from two opposite directions towards each other. The atomized particles collide/contact with each other to aggregate, thereby creating the fast vanishing light scattering surface/volume at a specific spatial region in which the aggregated particles allow the incident light to be scattered, reflected and/or dissipated.

One embodiment relates to a haptic stylus includes: a stylus housing; a stylus tip attached to one end of the stylus housing, so as to be in contact with an interaction surface, such as a touchscreen; a stylus covering attached to a circumference of the stylus housing, so as to be movable with respect to the stylus housing along a longitudinal direction of the haptic stylus and so as to be gripped/held by user's fingers; and a first actuator configured to activate the stylus housing to thereby cause a stick-slip phenomenon between the stylus covering and the user's fingers gripping/holding the stylus covering thereby allowing the user's fingers to grip/hold the stylus covering while moving along the longitudinal direction of the haptic stylus.

One embodiment of the present invention provides a haptic device including a flexible and deformable tube, a liquid or gel-like substance, a sensor and an actuator. The flexible and deformable tube is affixed to a grip area to be gripped by a user. The liquid or gel-like substance is sealed within the tube and configured to transmit a pressure or/and pressure vibration vibration/pressure therethrough. The sensor is configured to detect the pressure or/and pressure vibration vibration/pressure generated in the tube. The actuator is configured to generate a haptic signal in the tube and/or the substance so as to be transmitted to the user.

One embodiment of the present invention provides a tactile imaging system. The tactical imaging system includes: a receptive field tactile control unit; and a connecting module configured to connect the tactile imaging system with a host system. In addition, the receptive field tactile control unit includes: a monitoring module configured to monitor a property of a human skin; and a tactile stimulation providing module configured to provide a tactile stimulation.

Tactile imaging system

Micropores penetrating a vibration platein a thickness direction thereof are formed, in which the vibration plateatomizes a solution by vibration of a piezoelectric vibratorthat generates ultrasonic vibration when current is applied thereto. In addition, the spraying time and the spraying interval time are controlled by turning on or off the current applied to the piezoelectric vibrator, such that a value of [50% particle diameter of spray particles in cumulative volume distribution]&#xd7;([spraying time]/[spraying interval time]) becomes 0.2 to 2.5 &#x3bc;m.

One embodiment of the present invention provides a living body stimulation device including: an envelope body having a living body contact surface which is to be brought into contact with a stimulation-target site of a living body; a propagation medium sealed in the envelope body and made of a liquid or gel material capable of transmitting a vibration and/or pressure; and an actuator configured to apply the vibration and/or pressure to the propagation medium. The vibration and/or pressure applied to the propagation medium by the actuator propagates through the propagation medium to the living body contact surface of the envelope body, to thereby stimulate the living body.

Living body stimulation device and living body stimulation method

An atomizer is provided to include a pivot member mounted on an upper portion of a device body so as to pivot up and down. The pivot member includes a holding portion configured to hold a vibrating plate movable up and down relative to the pivot member so as to bring the vibrating plate into face contact with the upper end surface of a wick by its own weight when the pivot member pivots downward. The device body includes a restriction portion that comes into contact with the pivot member to restrict the pivoting downward of the pivot member, while the vibrating plate is in face contact with the upper end surface of the wick.

Atomizer

An ultrasonic atomizing unit is provided which can spray fine particles of a liquid farther without greatly increasing a voltage applied to a piezoelectric vibrator and using a fan. An annular atomizing member () is provided and ultrasonically vibrates a vibrating plate () with a piezoelectric vibrator () to atomize a liquid. The atomizing member () is elastically sandwiched and held by a casing () through a pair of annular elastic rings () that are in contact with the atomizing member (). A maximum facing width in a radial direction between each annular elastic member and one surface of the atomizing member () on one side in the radial direction from the center of the atomizing member () is 40% of a radial direction width of the piezoelectric vibrator () on one side in the radial direction from the center of the piezoelectric vibrator ().
