Detailed explanation-1: -Drawbacks or disadvantages of Touch Screen Interface ➨It requires proximity of the user to operate. User must be within reach of the touch screen display. ➨Hands and fingers often obscure the screen information while selecting the desired options. ➨Battery operated touch screen devices consume more power.
Detailed explanation-2: -Easily damaged – touch screens, partly due to their portability, can be fragile. With capacitive multi-touch function, various operations/inputs (eg: zoom-in/zoom-out, rotation) are possible. Expense – Large touch screens can be a lot more expensive than using traditional keyboard and mouse solutions.
