Helping blind people . 

 Some years ago , when I was still a university student studying Electronics , a problem was 

 identified with blind people , who needed a portable machine to detect currency in bills . 

 In my country there is an institution for blind people known as the Hellen Keller Institute , 

 in which care is given to this population . 

 The Storytelling tool was used to gain a better understanding of what this group of people 

 really needed . 

 A visit was made to the Hellen Keller Institute to propose a meeting with some blind 

 people so that through some stories told by them of a certain problem they were 

 experiencing in terms of being vulnerable to fraud , they would discuss the need for these 

 people in terms of detecting counterfeit bills and thus avoiding robberies and deception of 

 this population when they charge for the jobs and services they perform for their daily 

 sustenance . Something that would also lead them to feel a state of independence in terms 

 of asking for help from other people with good visual health to detect counterfeits and 

 would give them more confidence and autonomy in themselves . 

 To gain the trust of the participants , I told them a story about a friend who had been 

 scammed and had a very expensive radio recorder stolen from him . How he felt bad for 

 having fallen into a trap which had also generated a loss of self - confidence and how this 

 that happened to my friend motivated me to think about doing something for people 

 vulnerable to scams and so on . The idea of a ticket detection machine for blind people 

 was born . 

 The meeting was held with seven blind people , who had had problems when unscrupulous 

 people had paid them with false bills , causing a significant financial loss for them . 

 These people commented that although they had checked the banknotes , the copies were 

 so good that they passed the touch test as if they were real banknotes . Also , the smell test 

 since the banknotes have a certain aroma , things that a person with normal eyesight does 

 not have in mind . 

 On the other hand , information was sought from banknote detection machines , which led 

 to the knowledge that banknote detection machines at that time were only capable of 

 detecting a single type of banknote and , furthermore , they were made to be used only by 

 people they have no visual problems . 

 One of the main underlying problems is that there are several denominations of 

 banknotes , which must be correctly identified so that blind people can recognize whether 

 it is a real banknote or a counterfeit . 

 The questions revealed missing elements for the creation of a device which would help 

 with the solution of the problem . Listening to the stories told by these people helped 

 them to be able to think like a blind person , that is , to put themselves in the place of the 

 blind person and see their world from their same perspective in order to solve the 

 problem . 

 With the needs presented by this group of blind people , it was possible to understand 

 more about the problems they face every day , and it was possible to think about the 

 design of a prototype to try at least to cover all the needs exposed as a group , making the 

 necessary adjustments that allowed it to function and could help blind people to be less 

 prone to scams .
