Part 3 - User Interaction
In continuing with 10 Steps to Understanding Car Computers, I will next cover how the user interacts with the car computer. Like everything in car computers, there are numerous choices.
The most standard way to interact with the carpc is via a touch screen. Most people install 7-8inch LCD touch screens that provide image display and easy user input. The perfered style of screens use vga input over other method like composite or s-video. The main reason is that they provide a large large of resolution to be run on them. When using the composite video screens, the text can be fuzzy and hard to read. Below is a Lilliput LCD Touch screen.
Is the past, and still some now, were using Character LCD screens. These provided a few lines of text and limited characters per line.
My choice and personal favorite is voice input. Using a few software packages (or writing my own) allows the driver to completely interact with the system without have to touch the screen or any buttons. I have found it very fun to play with and works pretty well.
These are just a few of the above combinations discussed in a bit more detail. Part of the fun of building a carpc is the freedom to chose what you want. You can have 5 LCD screens or none and still have a wonderful, original car computer.
