Olfactory display

Abstract

The present invention provides an olfactory display (10) which includes a housing (12) that has a spray opening (22) and presents aromas in a temporally and spatially limited range. An aroma chamber (14) that has an in-draft opening (26) and an aroma outlet (24) linked to the spray opening (22) is formed in the housing (12), and an aroma source (20) in a solid form is accommodated in this aroma chamber (14). In addition, a blowing force source (16) provided with a diaphragm (34) to which a piezoelectric element (32) is attached is provided in the aroma chamber (14). When an aroma is presented, air inside the aroma chamber (14), which includes an aroma component in a gaseous form volatized from the aroma source (20) by the blowing force source (16) blowing air into the aroma chamber (14) from the in-draft opening (26), passes through the aroma outlet (24) and is sprayed from the spray opening (22).

Description

technical field

[0001] The present invention relates to an olfactory display, in particular to an olfactory display that prompts odors within a limited range of time and space. Background technique

[0002] In recent years, various olfactory displays have been proposed that present smells (olfactory information) in conjunction with audio-visual displays such as TVs and personal computers for the purpose of presenting information with a high sense of presence and immersion to the user. Here, when a certain smell is to be presented over a certain period of time, it is sufficient to simply diffuse the smell into the space. However, temporal control (temporal locality) of scent cues is required in order to present odors in a manner consistent with, for example, switching scenes of content presented by an audiovisual display. In addition, in order to present an odor only to, for example, a target person, it is necessary to spatially control (spatial locality) the odor presentati...
