Typical Applications

•E-compass applications

•Static orientation detection (portrait/landscape, up/down, left/right, back/front position identification)

•Notebook, e-reader, and laptop tumble and freefall detection

•Real-time orientation detection (virtual reality and gaming 3D user position feedback)

•Real-time activity analysis (pedometer step counting, freefall drop detection for HDD, dead-reckoning GPS backup)

•Motion detection for portable product power saving (auto-sleep and auto-wake for cell phone, PDA, GPS, gaming)

•Shock and vibration monitoring (mechatronic compensation, shipping and warranty usage logging)

•User interface (menu scrolling by orientation change, tap detection for button replacement)
