System Architecture 🏗️

Baumann Skin Type Survey

1. Individual Question Score Calculation:

For each question in the survey, a score is calculated based on the selected option. The scoring function can be represented as:

$$ \text{{score}}(q_i) = \begin{cases} 1.0, & \text{if option 1 is selected;} \\ 2.0, & \text{if option 2 is selected;} \\ 3.0, & \text{if option 3 is selected;} \\ 4.0, & \text{if option 4 is selected;} \\ 2.5, & \text{if option 5 is selected (special case);} \\ 0.0, & \text{if the choice is invalid or for specific two-choice questions.} \end{cases} $$

For certain two-choice questions, a different rule applies:

$$ \text{{score}}(q_i) = \begin{cases} 0.0, & \text{if option 1 is selected;} \\ 5.0, & \text{if option 2 is selected.} \end{cases} $$

2. Aggregate Category Scores:

For each category (A, B, C, D), the total score is the sum of the individual question scores within that category. If (n) is the number of questions in a category, and (q_i) represents each question:

$$ \text{{Total Score for a Category}} = \sum_{i=1}^{n} \text{{score}}(q_i) $$

3. Moisture Score Calculation:

The moisture score is calculated specifically from certain questions, represented as (m_i). If we assume there are (k) questions contributing to the moisture score:

$$ \text{{Moisture Score}} = \left( \frac{\sum_{i=1}^{k} \text{{score}}(m_i)}{16} \right) \times 100 $$

4. Skin Type Determination:

Each category score is compared to a threshold to determine the skin type descriptor. This can be represented with the following conditions:

$$ \text{{Skin Type}} = \begin{cases} O, & \text{if A score} \geq 22; \\ D, & \text{otherwise;} \end{cases} ] [ \begin{cases} R, & \text{if B score} \geq 32; \\ S, & \text{otherwise;} \end{cases} ] [ \begin{cases} P, & \text{if C score} \geq 28.5; \\ N, & \text{otherwise;} \end{cases} ] [ \begin{cases} W, & \text{if D score} \geq 42.5; \\ T, & \text{otherwise.} \end{cases} $$

5. Result Compilation:

The final skin type is a string concatenation of the individual skin type descriptors from each category, represented as:

$$ \text{{Final Skin Type}} = \text{{Skin Type from A}} + \text{{Skin Type from B}} + \text{{Skin Type from C}} + \text{{Skin Type from D}} $$
