TECHNICAL FIELD
The present disclosure relates to methods and devices for generating a vibration by using a degree value of an adjective.
BACKGROUND
Among various types of haptic feedback, vibration-based haptic feedback (hereinafter referred to as “vibration feedback”) are widely used in various mobile devices, such as smart phones and tablet devices, game consoles, and realistic four-dimensional (4D) movie theaters. Also, since vibration feedback is more efficient than other types of feedback, the use of vibration feedback is on the increase currently.

wherein the relationship information between the degree value of the first adjective word, the degree value of the second adjective word, and the fundamental frequency is acquired from relationship information between the degree value of the first adjective word, the fundamental frequency, and the overlap ratio, and relationship information between the degree value of the second adjective word, the fundamental frequency, and the overlap ratio.

13. The device of claim 8,
wherein the relationship information between the degree value of the first adjective word, the degree value of the second adjective word, and the overlap ratio is acquired from relationship information between the degree value of the first adjective word, the fundamental frequency, and the overlap ratio, and relationship information between the degree value of the second adjective word, the fundamental frequency, and the overlap ratio.

14. The device of claim 9, wherein the at least one processor is further configured to:
acquire relationship information about a frequency, an amplitude, and a perceiving intensity, and
modulate the amplitude of the at least one vibration based on the acquired relationship information about the frequency, the amplitude, and the perceiving intensity.

15. A non-transitory computer-readable recording medium that stores one or more programs including instructions that, when executed by a computer, causes at least one processor to perform a method for generating a vibration by a device based on an adjective word, the method comprising:
setting, by the at least one processor, for each of a plurality of adjective words, at least one fundamental frequency and a degree value of senses corresponding to an adjective word, the adjective words indicating senses provided to a user through the vibration of the device, and the degree value of senses indicating a degree of the senses provided to the user through the vibration of the device;
displaying at least one adjective words and the degree value of senses corresponding to the adjective words;
receiving at least one user input for selecting an adjective word among the displayed adjective words; and
generating, by the device, at least one vibration having the at least one fundamental frequency, the at least one fundamental frequency being based on the selected adjective word and the degree value of senses corresponding to the selected adjective word, according to the setting,
wherein a certain adjective word comprises a first adjective word and a second adjective word, and
wherein the setting of the at least one fundamental frequency comprises: setting at least one overlap ratio;
acquiring relationship information between a degree value of the first adjective word, a degree value of the second adjective word, and the fundamental frequency; and
acquiring relationship information between the degree value of the first adjective word, the degree value of the second adjective word, and the overlap ratio.
