# Haptic Glove TV Device for People with Visual Impairment
## 6 Analysis and Evaluation of Results
### Glove Requirements for Future Use and Improvements  
The last stage recorded was a survey that included questions to find future requirements and uses that can be given to the haptic device, Table 5 shows the questions and statistical results. However, we show the results that we consider most important in our analysis because if we take it into account, we could have a second version of the glove with new functions and considerable improvements. Figure 26, question 1, shows varied results of the level of perception that users have about the time that has elapsed in a soccer match. In fact, they were asked, during the course of the match, how long they think they are playing? Some people came very close to the game time, but others did not give a close answer. With this, it was determined the need for some mechanism to indicate the playing time. Since they manifested that they have problems in knowing the time of game in a soccer match, especially when they do not start to listen the game from the beginning. That they have to ask someone else to indicate the time that has passed on the television chronometer. The same problem exists with the score of the game. Thus, they cannot watch the scoreboard that always remains visible on the television, and this can be seen in Figure 26,  
Figure 26: Evaluation results of requirements for future use and device improvements. question 2, where most of the participants believe that the need to have an on-demand sound to indicate the score of the match is very high. Figure 26, question 3, shows that when a goal occurs, most people are unaware of which team scored a goal. Additionally, when they are not familiar with the players' names and the narrator does not indicate who possesses the ball, there is difficulty in identifying who scored the goal. Therefore, it may be a requirement that when a goal is scored, it needs to be indicated by the sound of which team scored it. Figure 26, question 4, shows that there are a high number of people who indicate that when the referee whistles a foul on the field, they do not understand for whom the foul was whistled or who committed it. This is because they are generally not familiar with the names of the players heard in the narratives, which is shown in Figure 26, question 5. However, also there are soccer fans who have all the team's player lists in their minds. Figure 26, question 6, shows the need to increase buttons, gestures, and voice command in the glove, which, when carried out, will result in a response, e.g., time, score, match statistics, etc. Figure 26, question 7, shows that there is great enthusiasm among participants to try the glove on other sports or applications. Other questions investigated which sports or applications they imagined could be applied to the glove, and the responses were varied. The other sports they mentioned were boxing, basketball, volleyball, tennis. It also occurred to them that it could be a useful device for them to play chess, electronic games, educational applications. They went further and proposed that the glove through vibrations could act as a guide for them to identify obstacles, potholes, stands, among others. Furthermore, since some of the participants play blind soccer, also known as blind football, they came up with the idea that the haptic device could guide them to play a soccer blind game. The main problem they face when playing soccer for the blind is that the fans scream or cheer for them, and that noise or ambient noise does not allow them to hear the bells that sound inside the balls they use. This makes it difficult to give continuity to the game. In the last part of the survey, the participants were told about ten plays or situations in a soccer match. Focus on knowing which of these were more difficult for them to perceive and propose a solution with that information. Apart from the ball's location on the field, this type of information can be sent through vibrations.
