Algorithm 1

A set of fuzzy rules engaged with the dynamic NF model for the affective design of mobile phones.

Fuzzy rule 1:

If 𝑥₁ is MF₁₂ and 𝑥₂ is MF₂₁ and 𝑥₃ is MF₃₁ and 𝑥₄ is MF₄₁ and 𝑥₅ is MF₅₁ and 𝑥₆ is MF₆₃ and 𝑥₇ is

MF₇₂ and 𝑥₈ is MF₈₃, Then 𝑦_𝐻=(0.7832−0.3457𝑥₁+0.4648𝑥₂−0.0777𝑥₃,−0.1483𝑥₄−0.5625𝑥₅

+ 0.1666𝑥₆+0.1792𝑥₇−0.4252𝑥₈).

Fuzzy rule 2:

If 𝑥₁ is MF₁₅ and 𝑥₂ is MF₂₄ and 𝑥₃ is MF₃₅ and 𝑥₄ is MF₄₂ and 𝑥₅ is MF₅₂ and 𝑥₆ is MF₆₁ and 𝑥₇ is

MF₇₁ and 𝑥₈ is MF₈₂, Then 𝑦_𝐻=(0.6287+0.2538𝑥₁+0.3483𝑥₂−0.1493𝑥₃+0.1085𝑥₄−0.4197𝑥₅

− 0.4555𝑥₆−0.2626𝑥₇−0.06333𝑥₈).

Fuzzy rule 3:

If 𝑥₁ is MF₁₁ and 𝑥₂ is MF₂₃ and 𝑥₃ is MF₃₄ and 𝑥₄ is MF₄₃ and 𝑥₅ is MF₅₄ and 𝑥₆ is MF₆₄ and 𝑥₇ is

MF₇₄ and 𝑥₈ is MF₈₄, Then 𝑦_𝐻=(0.2227+0.009144𝑥₁−0.1078𝑥₂+0.03565𝑥₃+0.1077𝑥₄+0.1951𝑥₅

+ 0.1998𝑥₆+0.08163𝑥₇+0.004227𝑥₈).

Fuzzy rule 4:

If 𝑥₁ is MF₁₄ and 𝑥₂ is MF₂₅ and 𝑥₃ is MF₃₂ and 𝑥₄ is MF₄₄ and 𝑥₅ is MF₅₅ and 𝑥₆ is MF₆₂ and 𝑥₇ is

MF₇₅ and 𝑥₈ is MF₈₁, Then 𝑦_𝐻=(0.2448+0.05979𝑥₁+0.02159𝑥₂,−0.04047𝑥₃+0.2202𝑥₄+0.07846𝑥₅

− 0.01265𝑥₆−0.01162𝑥₇+0.1297𝑥₈).

Fuzzy rule 5:

If 𝑥₁ is MF₁₃ and 𝑥₂ is MF₂₂ and 𝑥₃ is MF₃₃ and 𝑥₄ is MF₄₅ and 𝑥₅ is MF₄₃ and 𝑥₆ is MF₆₅ and 𝑥₇ is

MF₇₃ and 𝑥₈ is MF₈₅, Then 𝑦_𝐻=(0.3077−0.001267𝑥₁+0.001715𝑥₂−0.291𝑥₃−0.1659𝑥₄−0.3424𝑥₅

+ 0.1052𝑥₆+0.496𝑥₇+0.2649𝑥₈).

Note: 𝑦_𝐻 is the predicted value with regard to the rating of handiness of mobile phone
