Abstract: An encryption method for encrypting a piece of information using a spiral pattern, includes: creating, by a processor, an encryption code table that contains a plurality of encryption codes, and a plurality of numerical values respectively allocated to the plurality of encryption codes; encrypting, by the processor, the piece of information using the encryption code table, to thereby obtain an array of the numerical values; and converting, by the processor, each numerical value in the array to a wave segment having a wavelength corresponding to a multiple of said each numerical value, each of the plurality of wave segments being connected to each other to form a continuous wave that spirals outward in the spiral pattern.

Abstract: A vibration device that vibrates in accordance with a reproduction signal. The vibration device includes: a vibration generation section including a speaker that is configured to generate a sound wave in accordance with the reproduction signal, to thereby generate vibration; a power generation section including a piezoelectric element that generates a current corresponding to the reproduction signal by the vibration of the vibration generation section; an electromagnetic wave generation section including a coil substrate, into which the current generated by the power generation section flows to thereby generate an electromagnetic wave that is spatially radiated; and a body section including a cylindrical case that accommodates the vibration generation section, the power generation section, and the electromagnetic wave generation section. The vibration generated by the vibration generation section is transmitted to a user via the case.

Abstract: Provided is an apparatus for bodily sensation of bone vibration. The apparatus includes: an electric signal generator configured to generate an electric signal; an amplifier configured to amplify the electric signal from the electric signal generator; a vibrator configured to transduce the amplified electric signal transmitted from the amplifier into a mechanical vibration; a metal vibration member directly coupled to a vibration generator of the vibrator, the vibration member having a seat portion configured to contact with a human body and a side surface portion continuing with the seat portion; and a seat support member provided on a back surface of the seat portion, covering the vibrator, and configured to be placed on a placement plane and to support the seat portion above and apart from the placement plane so as to keep vibrational energy from being conducted to the placement plane.

Abstract: A skull vibration device includes: an electrical signal generator configured to generate an electrical signal; an amplifier configured to amplify the electrical signal from the electrical signal generator; a vibration generator configured to convert the electrical signal transmitted from the amplifier to a mechanical vibration; a metal vibration member to which a vibration generating portion of the vibration generator is directly coupled, and which is configured to cover a skull of a human body with a predetermined spacing left between the vibration member and the skull; and a vibration member supporter configured to suspend the vibration member while preventing direct or indirect contact of the vibration member with the human body, and to keep the vibration member at a predetermined distance from the skull. A vibration generated from the vibration member is transferred to the skull through a vibration of air.

Abstract: A method for using a third-person VR system including: a non-transmissive head mount display, an imaging section, and a relay section, includes: attaching a non-transmissive head mount display to a head of a user such that the non-transmissive head mount display enables the user to see an image; capturing a moving image including at least the user wearing the head mount display by an imaging section; sending, by a relay section, the moving image captured by the imaging section to the head mount display; sending, by the relay section, the image captured by the imaging section by using a communication line such as Internet, to the head mount display in real time; and allowing the user to perform an activity while the user see an image of the user displayed on the head mount display.
