Resumo: | In last decade, tablet devices become more convenient and comfortable electronic devices than laptop. Its touchscreen’s property creates a natural feeling for users while moving objects that appear on the screen. However, the loss of pressing-buttons sensation requires the users to look at the screen during touching and gesturing, and every taps provide the same feeling to the users’ fingers. This type of problem discourages the visual impaired people to use the devices. Therefore, the paper aims to challenge the di culty to hearten them to compose with and use tablet devices more than to only listen to the devices’ audio. Ad- ditionally, learn how to type in a new way is tragedy. The new approach is developed to create an e↵ective fingers detection for braille touchscreen keyboard application and to provide the same method of typing like they press buttons of their old style braille keyboard. The proposed method can track and identify all the eight fingers in both upright and upside- down directions of the tablet devices. The paper also explains in detail of every steps of the method and forms a complete algorithm at the end with the considerate analysis and results. The proposed method fulfills the requirement for the visual impaired people. |
