Step-by-Step Derivation of the Suitability Score:
- Define Display Characteristics: Each common Calculator Display Type (Segment LCD, Dot Matrix LCD, VFD, OLED, LED Segment) is assigned a base score (1-5) for key characteristics: Readability in Low Light, Color Capability, Power Efficiency, Cost Effectiveness, and Graphics/Animation. A higher base score indicates better performance in that characteristic for that display type.
- User Preference Weighting: Your input values (1-5) for each characteristic act as a “weight” or importance multiplier. For example, if you rate “Power Efficiency Importance” as 5, that characteristic’s base score for each display type will be multiplied by 5, making it a significant factor in the final score.
- Digit Count Adjustment: The “Desired Number of Digits” input influences the base suitability for certain display types. For instance, segment displays are highly suitable for fewer digits, while dot matrix or OLED displays excel with higher digit counts for complex expressions. This adjustment is applied to the base score before weighting.
- Calculate Weighted Score: For each display type, the adjusted base scores for each characteristic are multiplied by your corresponding preference weights. These weighted scores are then summed up to get a total suitability score for that specific display type.
- Recommendation: The Calculator Display Type with the highest total suitability score is recommended as the best fit for your requirements.
