# 7.1.2 Choosing programs and parameters

Within the systems settings on a TV, tailoring for individual taste has become ever more important. This is not only for personal preferences, but also to help users adjust in response to their particular requirements (e.g. colour blindness). Menus (navigated by the remote and/or voice) allow the user to adjust many system settings, such as: colour, sound, connectivity, internet access, Bluetooth and other device access.

These are complex functions at times, but gone are the days of tuning to individual stations and pressing buttons to set and store channels. Automation and system intelligence carry out these functions for the user, allowing the person to concentrate on how they use the technology, and the aesthetics.

## Activity 18 A simple interface

What kind of interface would you expect on a very simple tablet?

### Discussion

Since a typical tablet has no keyboard, a touch screen is required. How the screen is then laid out and navigated becomes important, particularly when utilising context-specific gesture control, as is the case with Android and Apple interfaces.

Buttons on the tablets are usually limited to on/off and volume controls. Everything else is contained in the UI (user interface).
