ABI Research anticipates that the sensor-driven user interface (UI) will be an emergent theme in the next wave of mobile UI innovation, turning objects, locations and people into networked, interactive elements. By 2013, 85 percent of smartphones will ship with GPS, over 50 percent will ship with accelerometers and almost 50 percent will have gyroscopes.
“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 Victoria Fodale. “The high-level operating system of a smartphone, which provides open application programming interfaces (API), 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. 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. However, added functionality must be balanced with ease of use. “There is an inherent paradox with technology,” says Fodale. “As mobile devices integrate more technology, the UI must be kept simple enough to be intuitive for the user.”
A new ABI Research study, “Mobile Device User Interfaces,” examines the key market and technology trends for mobile device UIs. It highlights the UIs of leading device OEMs, and examines UI technologies including frameworks, touchscreens, GPS, sensors and other components. Forecasts include smartphones shipments by OS and region and mobile augmented reality application downloads, as well as the attach rate for key sensor and other components.
