Hardware rescources of a HCI
memory
If a HCI has a lot of options then the size of file needed to store the HCI will be large, as the HCI is almost a program in its own right.
processing power
When a user is communicating with HCI, processing power will be needed to complete the requested tasks.
Type
There are displays that are touch enabled and not touch enabled.
User interactions methods for HCI , advantages and disadvantages for each
Voice
Advantage
More natural method for humans to communicate instruction
disadvantage
If you have an accent it might not understand you
Keyboard and mouse
advantage
shortcuts for users
disadvantage
Have to learn the layout
touch and gesture
advantage
Easy to use
disadvantage
may not be accessible for disabled
Hardware considerations for HCIs
display types
light emitting diode (LED)
LEDs generate their own backlight, meaning the backlight does not have to be built in to the device.
organic light emitting diode (OLED)
OLEDs produce its own light, meaning it uses less power and is thinner than the others. Can be flexible.
liquid crystal display (LCD)
LCDs use a separate backlight to illuminate the display from behind
size
Advantages and disadvantages of wireframes
advantages
Informational and graphical elements can be positioned and moved.
The size of elements can be changed.
The design can be finalised in a low fidelity without the clutter.
High fidelity can be used in testing process.
Changes can be made efficiently
disadvantages
Interactive features cannot be shown in low fidelity.
High fidelity can become over designed.
two disadvantages of a mindmap
Can be difficult for others to understand
Correct type of mindmap has to be used
wire frame for an app
