An augmented reality (AR) laboratory system provides scent-based feedback synchronized with visual augmentations of chemical experiments. The system utilizes a video see-through AR display device to capture real laboratory settings, overlaying virtual chemical substances and reactions onto a physical lab vessel analog. The vessel incorporates an olfactory output module, including a miniature fan and scent reservoir, emitting fragrances representative of virtual chemicals or reaction byproducts. A machine-readable marker affixed to the vessel enables precise tracking and identification by the AR device, allowing the processor to retrieve corresponding reaction data. When a user conducts virtual chemical experiments, such as mixing compounds, the system dynamically generates realistic visual simulations and simultaneously triggers accurate scent emissions (e.g., odors of acids or organic solvents) matched to the visual events. By engaging the user's olfactory sense alongside visual cues, this AR chemistry system significantly enhances educational immersion without exposing users to hazardous substances.

The application relates to the technical field of general chemical or physical laboratory equipment, and discloses an automatic experiment system for special mortar formula research and development. The system monitors the operation parameters of a stirring unit through a central controller, compares a real-time process fingerprint with a failure fingerprint mode library after entering a stable stage in a mixing process, and adaptively adjusts a judgment condition according to a baseline value of an initial state of the system. Therefore, whether to terminate the process in advance before the mixing is completed is decided. The application changes an experiment process from a rigid time sequence into a dynamic process based on real-time feedback and resource allocation of process evolution information, so that invalid investment of subsequent time and resources caused by waiting and processing samples that are destined to be unqualified in the initial mixing stage is avoided.

An augmented reality (AR) chemistry apparatus simulates exothermic chemical reactions through synchronized visual and thermal feedback. The system utilizes a video see-through AR display device to overlay virtual reaction effects—such as color changes, gas bubbles, or luminescence—onto a physical laboratory vessel analog. The vessel is equipped with a thermal feedback element, such as an integrated heating diode, which is precisely controlled by the system's processor. A unique identification marker on the vessel enables the AR device to recognize it and retrieve stored reaction parameters, including an exothermal reactivity value determining heat generation. When the user initiates a virtual reaction, the processor simultaneously renders visual cues (e.g., liquid color transitions or virtual smoke) and increases vessel temperature via the thermal element, allowing users to tangibly experience realistic warmth corresponding to reaction intensity. Optional additional sensors, like olfactory modules emitting scents, can further enhance realism, deepening user immersion.

An augmented reality chemistry system that realistically simulates the mass and weight of virtual substances. The system employs a video see-through AR device to overlay virtual liquids or solids into a physical lab vessel analog held by the user. The physical vessel analog incorporates a fluid flow system with a reservoir and bidirectional pump under computer control. This allows the system to inject a certain volume of real, weighty fluid (e.g. water) into the vessel or withdraw it, thereby changing the vessel's weight in the user's hand to match the presence or absence of virtual matter. A tracking marker on the vessel lets the AR device's processor identify the vessel and retrieve augmentation parameters. As the user performs a simulation (such as “filling” the vessel with a virtual liquid), the processor simultaneously operates the pump to add real fluid, increasing the vessel's mass to correspond to the virtual fill level.
