Abstract: At present, the mobile phone is wildly used by the elderly. However, the evaluation of mobile phones for the elderly usability is still lack, which has obviously disadvantage for the elderly’ mobile phones research and development. A way of assessment based on cloud model is proposed aiming at the problem drawn from mobile phones for the elderly usability. Evaluation index system is established. In addition, entropy weight and analytic hierarchy process are combined to ensure the relative weight of each index factor, and to complete the evaluation of index information through cloud model. The analysis of living example shows that this way of assessment can effectively deal with the uncertainty and fuzziness of elderly’ mobile phones usability assessment, it can improve  objective and accurate of the usability assessment result, which will provide a theoretical basis for the elderly’ mobile phones in terms of usability design.
