Formula & Theory — Rainy Day Activity Happiness Score
The Rainy Day Activity Happiness Score uses a weighted additive model:
HappinessScore = ActivityBase × 0.7 + DurationBonus + InterestBonus + SocialBonus
ActivityBase = base score for the selected activity (60–80 pts)
DurationBonus = clamp(durationHours / 2, 0, 1) × 10
InterestBonus = ((interest − 1) / 4) × 20
SocialBonus = 0 (solo) | 8 (partner) | 15 (group)
HappinessScore = clamp(round(sum), 0, 100)| Symbol | Meaning |
|---|---|
| ActivityBase | Preset happiness base score for each activity type |
| durationHours | Planned activity duration in hours |
| interest | Personal interest match rating (1–5) |
| SocialBonus | Bonus points for social participation mode |
Score bands:
| Score | Level |
|---|---|
| 0–39 | Low Enjoyment |
| 40–59 | Moderate Enjoyment |
| 60–79 | Good Enjoyment |
| 80–100 | Excellent Enjoyment |
Assumptions and Limits
The activity base scores are generalized estimates derived from psychological research on indoor leisure activities and mood. Individual responses may vary significantly. The model assumes normal indoor rainy-day conditions and does not account for personal mental health status, fatigue levels, or environmental factors.
