Question

Write a two to three (2-3) page paper in which you:

Compare how the gestures data is generated and represented for interpretation in each of the following input devices. In your comparison, consider the data formats (radio waves, electrical signal, sound, etc.), device drivers, operating systems supported, and interoperability between devices.

Explain how each of the following input devices detects and generates a depth map in order to detect the location of the user. (Hint: Depth-aware cameras for input.)

Some industrial controls, automated manufacturing robots, and control systems depend on sensor generated and accelerometer data during processing. Analyze the accuracy of the input generated by each of the following input devices compared to electrical signals based methods of processing.

Select one of the three devices (Microsoft Kinect, Wii Remote, or Smartphone accelerometers) that you believe provides the best accuracy and explain why.

End users may be concerned with the safety of Microsoft Kinect, the Wii remote, or Smartphone accelerometers. Suggest ways of making these devices safe for industrial control systems, production robots, and other business applications that use sensors and accelerometers.

Explanation / Answer

PlayStation Move is a motion-sensing game controller platform by Sony Computer Entertainment (SCE), first released for the PlayStation 3 (PS3) video game console. Based around a handheld motion controller wand, PlayStation Move uses inertial sensors in the wand to detect its motion, and the wand's position is tracked using a PlayStation webcam. First revealed on 2 June 2009, PlayStation Move launched in mainland Europe and most Asian markets on 15 September 2010, in Australia on 16 September 2010,in North America and the UK on 17 September 2010and in Japan on 21 October 2010. Hardware available at launch included the main PlayStation Move motion controller, a supplementary PlayStation Move navigation controller, and an optional PlayStation Move charging station. It competes with the Nintendo's Wii Remote Plus and Microsoft Corporation's Kinect motion controllers introduced with the Wii and Xbox 360 home consoles, respectively.

Although PlayStation Move was introduced on the pre-existing PlayStation 3 console, Sony stated prior to release that it was treating Move's debut as its own major "platform launch", with an aggressive marketing campaign to support it.The tagline for PlayStation Move from E3 2010 was "This Changes Everything",including partnerships with Coca-Cola, as part of the "It Only Does Everything" marketing campaign which debuted with the redesigned "Slim" PlayStation 3.

In 2013, Sony unveiled the PlayStation 4, revealing that the console will support PlayStation Move, providing greater tracking precision via the PlayStation Camera, a depth-sensing stereo camera.

Microsoft Kinect

Kinect is a line of motion sensing input devices by Microsoft for Xbox 360 and Xbox One video game consoles and Windows PCs. Based around a webcam-style add-on peripheral, it enables users to control and interact with their console/computer without the need for a game controller, through a natural user interface using gestures and spoken commands. The first-generation Kinect was first introduced in November 2010 in an attempt to broaden Xbox 360's audience beyond its typical gamer base. A version for Windows was released on February 1, 2012.Kinect competes with several motion controllers on other home consoles, such as Wii Remote Plus for Wii, PlayStation Move/PlayStation Eye for PlayStation 3, and PlayStation Camera for PlayStation 4.

Microsoft released Kinect software development kit for Windows 7 on June 16, 2011.This SDK was meant to allow developers to write Kinecting apps in C++/CLI, C#, or Visual Basic .NET

On February 21, 2011 Microsoft announced that it would release a non-commercial Kinect software development kit (SDK) for Windows in spring 2011, which was released for Windows 7 on June 16, 2011 in 12 countries. The SDK includes Windows 7 compatible PC drivers for Kinect device. It provides Kinect capabilities to developers to build applications with C++, C#, or Visual Basic by using Microsoft Visual Studio 2010 and includes following features:

Wii remote -

The Wii Remote also known colloquially as the Wiimote, is the primary controller for Nintendo's Wii console. A main feature of the Wii Remote is its motion sensing capability, which allows the user to interact with and manipulate items on screen via gesture recognition and pointing through the use of accelerometer and optical sensor technology. Another feature is its expandability through the use of attachments. The attachment bundled with the Wii console is the Nunchuk, which complements the Wii Remote by providing functions similar to those in gamepad controllers. Some other attachments include the Classic Controller, Wii Zapper, and the Wii Wheel, originally used for Mario Kart.The controller was revealed at the Tokyo Game Show on September 14, 2005, with the name "Wii Remote" announced April 27, 2006. It has since received much attention due to its unique features and the contrast between it and typical gaming controllers.The Wii's successor console, the Wii U, supports the Wii Remote and its peripherals in games where use of the features of the Wii U GamePad is not imperative.

      The Wii Remote has the ability to sense acceleration along three axes through the use of an ADXL330 accelerometer.The Wii Remote also features a PixArt optical sensor, allowing it to determine where the Wii Remote is pointing.Unlike a light gun that senses light from a television screen, the Wii Remote senses light from the console's Sensor Bar (model number RVL-014), which allows consistent usage regardless of a television's type or size. The Sensor Bar is about 20 cm (7.9 in) long and features ten infrared LEDs, five at each end of the barThe LEDs furthest from the center are pointed slightly outwards, the LEDs closest to the center are pointed slightly inwards, while the rest are pointed straight forward. The Sensor Bar's cable is 353 cm (11 ft 7 in) in length. The bar may be placed above or below the television, and should be centered. If placed above, the sensor should be in line with the front of the television, and if placed below, should be in line with the front of the surface the television is placed on. It is not necessary to point directly at the Sensor Bar, but pointing significantly away from the bar will disrupt position-sensing ability due to the limited viewing angle of the Wii Remote.

Smartphone Accelerometers - Smartphone accelerometers inside many electronic devices - tablets and phones - re-orient the screen as a user moves the device. This chapter opens by using a simple ball and spring device to explain the general principle of an accelerometer. It then describes:
