Design and Development of an Assisted Ball Positioning System for Soccer Matches with an HBBTV Server Integrated to a Haptic TV Glove Accessible to Visually Impaired People

Abstract:

Currently, although there are several developments that allow digital inclusion and accessibility of people with hearing or visual impairments to audio and video content through TV or any audiovisual streaming platform. These developments have not been sufficient and have not had the distribution and implementation that they should have. For example, there is still a latent problem with blind people who cannot follow a soccer game autonomously; they need an announcer to narrate the game with more details than an announcer for blind people. The objective of this work was to create a solution that by means of a semi-automatic supervised system, registers the position and route of the ball in a soccer field, using a design tablet that encodes its location in the form of vectors. These location vectors were generated by a remote server running a Python script and triggered by a Hybrid broadcast broadband TV server. The HbbTV server interacts with the TV user and when it receives an activation or activity start message from the user, the Python server sends the data to an Internet of Things (IoT) platform in the cloud, which in turn is connected to the haptic glove that uses haptic engines to generate vibrations that can be interpreted by the visually impaired with touch, thus making it possible to become an accessible and inclusive TV device for these vulnerable groups.
