TouchFLO 3D is a graphical user interface designed by HTC. It is used in the HTC Touch Family of Pocket PCs and was preceded by TouchFLO. TouchFLO 3D has been ported to Windows Mobile and Android, and is used in the HTC Touch Diamond, HTC Touch Pro, HTC Touch HD, HTC MAX 4G, HTC Touch Diamond2 and HTC Touch Pro2. The HTC Touch Viva, HTC Touch 3G and HTC Touch2 have a simpler version entitled TouchFLO 2D, where they have the same scrolling tab on the bottom of the screen, however they do not have any 3D visual effects. From the HTC Hero and HTC HD2 onwards, TouchFLO 3D has been heavily extended and is now being referred to, along with other usability improvements, as HTC Sense. The HTC Touch2 runs a version of TouchFLO 2D that is similar in style to HTC Sense.
The Today screen plugin is the main aspect of TouchFLO 3D, and consists of several tabs, which can be viewed by sliding a finger along the bottom bar or touching one of the visible icons. The tabs to the immediate right and left of the current tab can be accessed by swiping in the relevant direction. The tabs are:
Each tab has two soft keys which provide access to functions associated with a tab or tab customisation.
Instead of requiring users to touch the small status icons at the top of the screen (battery, volume, signal, etc.), the System Status Screen appears when the system status area is pressed, providing larger, finger-friendly buttons.
