Leveraging Accelerometers in Mobile Devices

12,556 views

Published on

In this session, we'll look at some cool things you can do today with accelerometer hardware found commonly in millions of mobile and devices, whether it be Apple's iPhone, or millions of other mobile devices from Nokia, Sony Ericsson, and other mobile device manufacturers. We'll explain basic fundamentals on how accelerometers work, as well as explore how to harness the power of accelerometer technology in a range of different devices.

Who this presentation is for: Developers who want to learn about some of the ways to tap into accelerometer on devices (not just iPhone).

What attendees will take from this presentation: Attendees will come away understanding how to better apply force and motion based feedback interaction to their mobile content through accelerometers; not only across not only iPhone, but also other mobile device platforms.

  26. 26. TYPES Capacitive Heat transfer Accelerometers sense a change in electrical capacitance, with respect to Accelerometers measure internal changes in heat transfer due to acceleration. The accelerometer senses the capacitance change between acceleration. A single heat source is centered in a substrate and a static condition and the dynamic state. suspended across a cavity. Thermoresistors are spaced equally on all four sides of the suspended heat source. Under zero acceleration the heat gradient will be symmetrical. Acceleration in any direction causes Piezoelectric the heat gradient to become asymmetrical due to convection heat Accelerometers use materials such as crystals, which generate electric transfer. potential from an applied stress. This is known as the piezoelectric effect. As stress is applied, such as acceleration, an electrical charge is created. Future Accelerometer Advancements In the next decade, NANO technology will create new applications and Piezoresistive dramatically reshape this area of technology. Accelerometers (strain gauge accelerometers) work by measuring the electrical resistance of a material when mechanical stress is applied MEMS-Based Accelerometers MEMS (Micro-Electro Mechanical System) technology is Hall Effect based on a number of tools and methodologies, which Accelerometers measure voltage variations stemming from a change in are used to form small structures with dimensions in the magnetic field around the accelerometer. the micrometer scale (one millionth of a meter). This technology is now being utilized to manufacture state Magnetoresistive of the art MEMS-Based Accelerometers. Accelerometers work by measuring changes in resistance due to a magnetic field. The structure and function is similar to a Hall Effect accelerometer except that instead of measuring voltage, the magnetoresistive accelerometer measures resistance. scott janousek

  82. 82. THE “NEXT” THINGS ... iSuppli predicts the industry for MEMS components will grow from $460 million last year to over $1.6 billion in 2013. The company also expects technology such as gyroscopes and projectors to hit the market as early as 2010. scott janousek
  83. 83. THE “NEXT” THINGS ... Magnetometer = Electronic Compasses Precise Location = Magnetometer + Accelerometer + GPS + (Camera) Next Generation = Augmented Reality + Precise Location scott janousek
