Identifying the right buttons from many other buttons on the screen and using one finger to touch can be hard when users navigate through an application without a sight. Moreover, this touch or click gesture might not really be natural gestures. Therefore, interactions were then reassigned by .mapping gestures to the intuitive meanings.. . For example, when human wants something, they tend to drag these objects toward themselves. Therefore, sliding down is assigned to "enter." When humans get frustrated, they might shake the object they are holding. So, shaking is used when the user cannot catch up and want to "replay" the voice guide

The challenge of this project is how the different types of feedback can coordinate to bring the best user experience. .The archetype of the flow was then created and called “Mode X“.. . This Mode X flow guides when and what feedback should function. The reason that it is called Mode X is that it can be applied to any mode by inserting valuables of each mode into this template, such as Transfer Mode or Bill Payment Mode. Moreover, each screen type is designed to be consistent with voice guidance behaviors. For example, in the first screen of that particular level, the voice guidance system will be coded to read the text on the second line, then the third line of the screen.
