Text Entry System for Smartphone Operation with Users Dominant Hand Smartphone is an electronic device which everyone uses every day. To enter text on smartphone, people use the text input methods which have been used for electronic devices so far. On the other hand, text input methods designed for smartphone have also been developed. As to the major input method for smartphones, one can hardly say that individual handedness is taken into account in the current interface design. For example, the button arrangement is quite easy for righthanded users to press any of the buttons. However, it is rather difficult for lefthanded users to use the buttons. Everybody enters text on smartphone every day. Therefore, it is important to provide a user interface equally usable for all. Accordingly, it is considered necessary to have a text input system for smartphones which everyone can use easily. Therefore, in this research, we propose a smartphone text entry system designed for operation with useru0027s dominant hand.

Evaluating Smartphone Screen Divisions for Designing BlindFriendly TouchBased Interfaces The blind people are facing numerous challenges in identifying, locating nonvisual items on touchscreen interfaces such as smartphones, tablets, etc. The occurrence of wrong touches and subsequently following an incorrect sequence of accessing objects and UI artifacts may mislead visually impaired people to perform common activities on smartphones. The need for designing usable interface for blind people to perform their common activities, such as placing a call, sending and receiving SMS and emails, etc., is already established. There are specific usability requirements that have to meet while developing usable interfaces for blind people. One of the most important aspects of usability requirements is the division of a touchscreen in such a way that should enable blind people to locate objects and nonvisual items on the screen easily and comfortably. This includes partitioning of touchscreen into two, three, four, five, eight, and nine partitions with respect to finger placement. The study aims to design usable user interfaces for blind people to perform common activities on smartphones. This paper reports on a datagathering study, which was conducted for finding the most usable design of different screen divisions. It also outlooks a usability analysis of the screen partitioning based on usability requirements including operational, orientation, the degree of understanding, consistency, semanticloss, navigational complexity, and time consumption in locating a particular object on a touchscreen. The novel contribution is a set of guidelines for designing easytouse semantically enriched user interface framework for blind people.
