Abstract Smart devices are effective in helping people with impairments, overcome their disabilities, and improve living standards. Braille is a popular method used for communication by visually impaired people. Touch screen smart can be to take input instantaneously convert it into natural language. Most of these schemes require location-specific that difficult users. In this study, position-free accessible touchscreen-based algorithm designed implemented It aims place the least burden on...

Flash memory offers attractive features, such as non-volatile, shock resistance, fast access, and low power consumption for data storage. However, it has one main drawback of requiring an erase before updating the contents. Furthermore, flash can only be erased limited number times. To overcome limitations, needs a software layer called translation (FTL). The basic function FTL is to translate logical address from file system like allocation table (FAT) physical in memory. In this paper, new...
