32-bit systems based on multimedia car navigation system

4.4.2. Touch screen and handwriting recognition

In recent years, achieved by touching and dragging the selection and adjustment of the input technology of electronic products, significant progress, but also a product of the competition can be important indicators of sales performance, such as Apple products in several prominent application of the above. Inside the 32-bit systems, we can easily through resistive touch screen to achieve these functions.

In navigation applications, we also need to support the writing function, to the special needs of the automotive environment, we can design a way to use Bluetooth wireless handwriting input panel, install the steering wheel for easy driver operation.

4.4.3. Simple and clear user interface

Man-machine interface design, product design is a key to how well and carefully designed to allow consumers to intuitively simple to operate products, is a problem.

Our man-machine interface design, to meet the majority of consumer habits and cognitive ability, while the performance of rapid response is the result of our various efforts.

4.5. Evoke a variety of ways the system

In more good ergonomic requirements, the system power state, wake up from standby mode the system we designed has the following:

Button

Remote control

Insert disc

Insert SD / MMC card

Insert USB device

4.6. Real Time Clock Design

Car users need to provide real-time clock, car audio usually need to design one.

Our design, but also the design of uninterruptible power real time clock provides accurate time reference to the system.

4.7. Multiple video signal inputs and disposal

4.7.1. Foreground and background operation

LCD screen in a multi-set driven by market demand, in-car multimedia design front and back of the display requirements.
