Personal Chemical Sensitivity Warning Method and System
People who suffer from multiple chemical sensitivities (MCS) have difficulty preventing symptoms due to a lack of awareness of the actual affecting compositions and/or whether such compositions are present in an environment. A person does not experience symptoms until after exposure, and then it is too late to prevent a reaction (e.g., allergy symptoms usually do not start immediately upon exposure). A person might know the cause of a reaction, but not have advanced warning of the state of the environment and cannot avoid it.
A method or system is needed to warn MCS sufferers of an environmental composition that might cause an unwanted physical reaction.
The novel contribution is a Personal Chemical Sensitivity Warning Method and System that utilizes a Chemical Analysis Sensor Device (CASD). The CASD is associated with the user’s personal handheld device (e.g., smart phone). The system uses a tiny chemical analysis sensor, which the MCS sufferer uses to teach the system to recognize an environment to which the user will have an allergic reaction. Upon experiencing symptoms, the user indicates the situation to the system. The system stores the latest environmental measurements for a given period. The system notes the levels of present chemicals and creates a new adjusted threshold (e.g., using a lower threshold for the measured chemicals).

The system warns the user the next time a similar chemical composition is observed. This allows the MCS sufferer to leave the location before the symptoms occur.
Additionally, the system can compare individual events to determine which chemicals were common in the different environments to narrow down the list of possible problem chemicals.
In an example embodiment, User A is an MCS sufferer.
1. User A is wearing the novel CASD and walks into a room where some chemicals are lingering that could trigger allergy symptoms
2. The CASD continuously measures the chemicals in the environment, but has not learned User A’s sensitivities
3. After 10 minutes in the room, User A starts to feel uncomfortable and experience shortage of breath, headache, and dizziness
4. User A indicates the symptoms on the associated smartphone and leaves the room
5. In respon...
