The choice of an appropriate input device for a product is based on both the type of device being used and the target market for that device. Suppose you are developing a device to be used for Internet access that will be marketed to senior citizens. What type of hardware would you select as the primary input device and why? Also mention the advantage and disadvantage of your selected input device
Explanation:
I would select a voice based input device. Senior citizens have several disadvantages that prevents them from using normal input devices such as touchscreens or keyboards.
Their hands are often afflicted with arthritis and this makes it difficult for them to type or to swipe across screens. A voice based input device would make their work much easier.
Advantages
- It would eliminate the need to type or swipe.
- It is easier and faster to use.
Disadvantages
- It would introduce errors in some words that are spoken incorrectly and thus distorting the results.
- It might not work for those with impaired speech
