In the next article are shown the results of various works of investigation in which the main objective is to calculate or obtain the Intention of Using a specific technology product or service, based on the Technology Acceptance Model (TAM) proposed by Fred Davis. Taking this model into account a Fuzzy Controller it is proposed as an alternative to the usual ways and methods suggested for calculating the Intention of Use, allowing anyone with access to a computer to estimate its value without needing the knowledge or the mathematical bases required to calculate it. To conclude, a comparison among practical TAM implementations is made, from its analysis it is noticeable that the Fuzzy Controller allows to obtain similar results to the ones gotten by the previously compared implementations, using much less resources and effort that the other methods.
