2.2 Hardware considerations GapFill

Touchscreens, OLEDs, LEDs and LCDs are all screen types in which  complex applicationsprocessorsinterfacesembedded HCIs can be built in.

The size of the screen has an impact on its usage. If the screen is   interactivelargesmallembedded, it may cause difficulty in usage because the HCI cannot be seen properly. However, if it is   smallvisuallargeweak, other components of the screen may not operate effectively because the screen is too wide.

An HCI also uses some resources like   memorysizean operating systemweight,   an operating systempixelsprocessing powerthickness and method of interaction.

The more options an HCI possesses, the   weakerclearerlowerlarger the file size will be, causing low memory capacity for the operating system. Similarly, if the  tasksprocessing powermemoryoperating system of the system is low, the tasks will process more slowly since options and sub-options of the HCI takes more power to operate.
