# Haptic Glove TV Device for People with Visual Impairment
## 7 Discussion  
The statistical data interpretation shows positive results that were analyzed in more detail in the analysis and evaluation of results section. The mean, mode, and median values in the three phases of the survey remained at high and very high values, except for those expected to have low and very low values as an ideal result. The standard deviation is acceptable and allows us to conclude that the procedure proposed for evaluating results was adequate. The values of kurtosis and skewness also helped us to understand better and interpret the results. In kurtosis, we have high and medium positive values that indicate an intense concentration of values in the central area of the distribution. In skewness, we have negative values in most cases, which means that the tail of its distribution is to the left, then it indicates that the greater concentration of values is in the scale of high and very high. Using the bootstrap method to better estimate the population size based on resampling of the original small sample helped us validate our statistical results. It was observed that the trend of the originally calculated means was maintained, and the variance was improved with a larger population considering a bilateral confidence interval of 95%, and this allows us to infer a true value of the mean parameter. It was also of great value to find a non-parametric method suitable for the small number of samples we had available and ordinal and non-quantitative data. The data we had were rather qualitative but based on a null hypothesis test, we can infer that the median results originally obtainedwere within those calculated with [PERSON]'s median test, also with a 95% confidence interval. These results encourage us to continue with the work and to carry out the execution of future works. After the analysis of the results, it is concluded that the glove proposal offers a real solution to the problem that blind people encounter when following a soccer match on TV. The glove's evaluation and performance tests proved that it is really useful and satisfactory to use it for this vulnerable group, which is somehow excluded from this type of audiovisual application. It can also be concluded that the haptic effect significantly improves the hearing experience that people with visual impairment live when attending sports programs on TV; the quality of experience felt by users was higher than when haptic feedback is not presented. It is worth discussing that, although the application was developed with a focus on delivering complementary information of the scenes that help the accessibility of blind people to the content of sporting events broadcast on television, whether they are live or pre-recorded in the case of VOD. With the feedback we received from the end-users, and based on their needs, it was determined that the glove gadget could also be used in the radio broadcast, in any sports video content regardless of the platform or transmission medium, even for physical events. For example, for visually impaired people attending a stadium or practicing soccer for the blind. To achieve this goal, we are currently working on finding a solution by applying artificial vision and deep learning techniques to automatically detect and track the ball automatically and generate the location coordinates. The proposal was novel for the specific application used, but the evaluation process determined that it could be adapted and used in other applications in the future. For example, in other sports, even unrelated to the initial focus, we gave it in this immersive and interactive TV work. The haptic device's construction in the form of a glove that fits the hand is feasible, was not obtrusive or intrusive to users, the bracelet fits perfectly on the forearm is comfortable and light. However, the size and weight could be improved in future work. This work mentions at least three proposals to send this data and achieve integration with television's broadcast system.
