"Viva Mais" is one of the first brazilian TV shows produced with focus on viewer interaction. The TV program discusses several subjects concerning health and welfare and offers some opportunities for an active participation of the TV viewer.

The "Ideal Weight" interactivity allows the TV viewer to type its height and then be informed of his/her ideal weight based on the body mass Index.

The body mass index (BMI), or Quetelet index, is a statistical measurement which compares a person's weight and height. Though it does not actually measure the percentage of body fat, it is used to estimate a healthy body weight based on how tall a person is. Due to its ease of measurement and calculation, it is the most widely used diagnostic tool to identify weight problems within a population, usually whether individuals are underweight, overweight or obese. It was invented between 1830 and 1850 by the Belgian polymath Adolphe Quetelet.

In this application, the height is typed in centimeters, using the numbered keys of the remote control, without commas or point.

The application control is implemented in NCL. BMI calculation and data input from remote control are implemented in an NCLua media node.
