The sensor-driven user interface will be an emergent theme in the next wave of mobile user interface (UI) innovation - turning objects, locations, and people into networked, interactive elements. By 2013, 85 percent of smartphones will ship with GPS, over a half will ship with accelerometers, and almost 50 percent will have gyroscopes.
Prompted by Apple’s UI innovations with the iPhone, smartphone OEMs have poured resources into UI design and development. Many OEMs, particularly those using Google’s Android OS, developed their own custom UI overlays.
Sensors will also help OEMs to innovate beyond a touchscreen UI for differentiation in the marketplace.
“The growth of sensors in smartphones will be driven by applications such as gaming, location awareness, and augmented reality, as well as the expansion of motion-based commands,” says senior analyst ABI Research Victoria Fodale.
“The high-level operating system of a smartphone, which provides open application programming interfaces (APIs), has facilitated the use of data from cameras, sensors, and GPS receivers.”
When an accelerometer is combined with a gyroscope, developers are able to create applications that can sense motion on six axes: up and down, left and right, forward and backwards, as well as roll, pitch, and yaw rotations.
“This gives a mobile device similar functionality to a game controller such as the Nintendo Wii.
However added functionality must be balanced with ease of use.
