Systems and methods for generating olfactory stimuli

A device or system is provided that provides olfactory stimulation and includes a piezoelectric vibration device for generating a scent corresponding to an action performed in a VR or AR environment or other application. In some embodiments, a user interacts with one or more game elements within a game program executed by a game engine, and in response to the interaction, the game engine may convey a series of commands that cause a piezoelectric device of the device to generate a scent to be experienced by the user. 提供了一种装置或系统，所述装置或系统提供嗅觉刺激，并且包括压电振动装置，所述压电振动装置用于产生与在VR或AR环境或者其他应用中执行的动作对应的气味。在一些实施方式中，用户与由游戏引擎执行的游戏程序内的一个或多个游戏元素进行交互，并且响应于该交互，游戏引擎可以传达导致装置的压电装置产生要由用户体验的气味的一系列命令。
