*FUNCTIONAL STRUCTURE
| USE CASES | SUB FUNCTIONS LIST |
|---|---|
| 1.User interface | First the machine should be switched on & it will display message to put the cloth inside it. Then after putting cloth the machine make use of IR sensors to detect the cloth presence and display a message to fold the cloth if cloth is detected and the folding starts. |
| 2.Cloth identification. | By the use of IR sensors the machine would be able to identify wether the cloth is put in the machine or not. |
| 3.Folding of cloth | After the IR sensors detects the cloth then the machine will start folding the cloth. |
| 4.Folding complete | After folding is complete the LED screen displays a message "cloth is folded" & then the user switches off the machine and takes out the folded cloth. |
