99-474: PlayStation Move ( プレイステーションムーヴ , PureiSutēshon Mūvu ) is a motion game controller developed by Sony Interactive Entertainment . Initially released in 2010 for use with the PlayStation 3 home video game console , its compatibility was later expanded to its successor, the PlayStation 4 in 2013, its PlayStation VR platform in 2016 and the PlayStation 5 in 2020 (2nd generation CECH-ZCM2 with microUSB
198-458: A fast Fourier transform of the TWF. The vibration spectrum provides important frequency information that can pinpoint the faulty component. The fundamentals of vibration analysis can be understood by studying the simple Mass-spring-damper model. Indeed, even a complex structure such as an automobile body can be modeled as a "summation" of simple mass–spring–damper models. The mass–spring–damper model
297-460: A "viscous" damper is added to the model this outputs a force that is proportional to the velocity of the mass. The damping is called viscous because it models the effects of a fluid within an object. The proportionality constant c is called the damping coefficient and has units of Force over velocity (lbf⋅s/in or N⋅s/m). Summing the forces on the mass results in the following ordinary differential equation: The solution to this equation depends on
396-430: A 1 Hz square wave . The Fourier transform of the square wave generates a frequency spectrum that presents the magnitude of the harmonics that make up the square wave (the phase is also generated, but is typically of less concern and therefore is often not plotted). The Fourier transform can also be used to analyze non- periodic functions such as transients (e.g. impulses) and random functions. The Fourier transform

Though the games with the bundles vary in each region, most bundles come with the PlayStation Move Demo Disc which contains demos for eleven different games. The bundles in Europe and Oceania however, come with the PlayStation Move Starter Disc with a setup tutorial and nine demos (same as the Demo Disc, except without Kung Fu Rider and Time Crisis ). The demos included are for
594-496: A gimmick. We found ourselves constantly itching for 'one more go'." The Guardian strongly criticized the Move's launch line-up, though it noted that the hardware was strong and that after playing with the Move it was "very hard to go back to the relative inaccuracy of the Wii ". The PlayStation Move won the 2010 Popular Science award for the "Most immersive game controller". In October 2010,
693-400: A killer combination for accurate and highly responsive motion-based gameplay, and we applaud Sony for getting the hardware right the first time." Kotaku praised its accuracy, design, use of augmented reality and said, "The Playstation Move is a intuitive, natural feeling way to play games and it brings with it not only a sense of increased immersion to already graphically immersive games, but
792-542: A live demonstration using an engineering prototype . Tentatively referred to as the PlayStation Motion Controller, the device was originally stated to be available in Q1/Q2 2010. As of August 2009, the controller features and design had not been finalized. Soon after revealing the motion controller to developers, Sony indicated that it was exploring the possibility of using the motion controller in combination with
891-439: A multitude of really cool ways, but of course it's only as cool as the games that use it" and that the launch line-up was not worth the purchase, though it believed that the Move would be worth the purchase in early 2011 due to a stronger line-up of games such as SOCOM 4: U.S. Navy SEALs and Killzone 3 . CVG gave the Move an extremely positive review and awarded it 9 out of 10, saying, "Sony's motion control gets beyond being
990-511: A new way to play with your reality and a refreshing form of colorful feedback." IGN gave the Move an 8.5 out of 10, noting that the launch line-up of games for the controller was insufficient though it summarized by saying, "At the end of the day, the PlayStation Move has the potential to be the best motion control system on the current crop of consoles." Joystiq praised the Move, saying, "The hardware's great, and I can see it being used in

Examples of these types of vibration include a washing machine shaking due to an imbalance, transportation vibration caused by an engine or uneven road, or the vibration of a building during an earthquake. For linear systems, the frequency of the steady-state vibration response resulting from the application of a periodic, harmonic input
1287-449: A real world environment, such as road inputs to a moving automobile. Most vibration testing is conducted in a 'single DUT axis' at a time, even though most real-world vibration occurs in various axes simultaneously. MIL-STD-810G, released in late 2008, Test Method 527, calls for multiple exciter testing. The vibration test fixture used to attach the DUT to the shaker table must be designed for
1386-597: A standard PlayStation 3 gamepad, such as having the player use "the motion controller as a sword and use DualShock 3 as a shield." One combination control scheme was demonstrated in September 2009 at the Tokyo Game Show for Biohazard 5: Alternative Edition , making particular use of the DualShock 3's analog stick. Although users found the setup to work well, some found holding a DualShock with one hand to be somewhat awkward. At

The consoles also had support for some devices in the previous generation of motion controllers depending on individual games. Valve 's Steam Controller was designed solely for use with PC's and required its Steam software. Its 6DOF sensors were made available for use by games published on Steam , and options available to users allowed
1584-533: A static object such as an arcade cabinet. Weighing scales using load cells have been used to detect balance changes and other body movements through changes in weight distribution and momentary fluctuation in measured weight. Unrelated to their use in motion tracking, mechanical sensors continue to see much use in joysticks and other controls that are found on motion controllers and other input devices. Ultrasonic triangulation and mercury switches were seen in optional peripherals for home video game consoles in
1683-402: A swing and letting it go, or hitting a tuning fork and letting it ring. The mechanical system vibrates at one or more of its natural frequencies and damps down to motionlessness. Forced vibration is when a time-varying disturbance (load, displacement, velocity, or acceleration) is applied to a mechanical system. The disturbance can be a periodic and steady-state input, a transient input, or
1782-423: A system behaves under forced vibration. The behavior of the spring mass damper model varies with the addition of a harmonic force. A force of this type could, for example, be generated by a rotating imbalance. Summing the forces on the mass results in the following ordinary differential equation: The steady state solution of this problem can be written as: The result states that the mass will oscillate at

An internal magnetometer is also used for calibrating the controller's orientation against the Earth's magnetic field to help correct against cumulative error (drift) by the inertial sensors. In addition, an internal temperature sensor is used to adjust the inertial sensor readings against temperature effects. The inertial sensors can be used for dead reckoning in cases which
1980-418: Is overdamped . The value that the damping coefficient must reach for critical damping in the mass-spring-damper model is: To characterize the amount of damping in a system a ratio called the damping ratio (also known as damping factor and % critical damping) is used. This damping ratio is just a ratio of the actual damping over the amount of damping required to reach critical damping. The formula for

Note: This article does not include the step-by-step mathematical derivations, but focuses on major vibration analysis equations and concepts. Please refer to the references at the end of the article for detailed derivations. To start
2277-414: Is called resonance (subsequently the natural frequency of a system is often referred to as the resonant frequency). In rotor bearing systems any rotational speed that excites a resonant frequency is referred to as a critical speed . If resonance occurs in a mechanical system it can be very harmful – leading to eventual failure of the system. Consequently, one of the major reasons for vibration analysis
2376-402: Is defined as: Note: angular frequency ω (ω=2 π f ) with the units of radians per second is often used in equations because it simplifies the equations, but is normally converted to ordinary frequency (units of Hz or equivalently cycles per second) when stating the frequency of a system. If the mass and stiffness of the system is known, the formula above can determine the frequency at which
2475-428: Is defined by the following formula. [REDACTED] The plot of these functions, called "the frequency response of the system", presents one of the most important features in forced vibration. In a lightly damped system when the forcing frequency nears the natural frequency ( r ≈ 1 {\displaystyle r\approx 1} ) the amplitude of the vibration can get extremely high. This phenomenon
2574-455: Is equal to the frequency of the applied force or motion, with the response magnitude being dependent on the actual mechanical system. Damped vibration: When the energy of a vibrating system is gradually dissipated by friction and other resistances, the vibrations are said to be damped. The vibrations gradually reduce or change in frequency or intensity or cease and the system rests in its equilibrium position. An example of this type of vibration
2673-420: Is less than the undamped natural frequency, but for many practical cases the damping ratio is relatively small and hence the difference is negligible. Therefore, the damped and undamped description are often dropped when stating the natural frequency (e.g. with 0.1 damping ratio, the damped natural frequency is only 1% less than the undamped). The plots to the side present how 0.1 and 0.3 damping ratios effect how
2772-488: Is not backwards-compatible with PS3). Conceptually similar to Nintendo 's Wii Remote and Microsoft 's Kinect , its function is based around controller input in games stemming from the actual physical movement of the player. The Move uses inertial sensors in the wand to detect motion while the wand's position is tracked using a PlayStation Eye or PlayStation Camera . The device was generally well received by critics, but has not quite met Sony's goals for integration into
2871-414: Is now compressing the spring and in the process transferring the kinetic energy back to its potential. Thus oscillation of the spring amounts to the transferring back and forth of the kinetic energy into potential energy. In this simple model the mass continues to oscillate forever at the same magnitude—but in a real system, damping always dissipates the energy, eventually bringing the spring to rest. When

For example, by applying a force to the mass–spring–damper model that repeats the following cycle – a force equal to 1 newton for 0.5 second and then no force for 0.5 second. This type of force has the shape of

3168-436: Is the vehicular suspension dampened by the shock absorber . Vibration testing is accomplished by introducing a forcing function into a structure, usually with some type of shaker. Alternately, a DUT (device under test) is attached to the "table" of a shaker. Vibration testing is performed to examine the response of a device under test (DUT) to a defined vibration environment. The measured response may be ability to function in

As the amplitude plot shows, adding damping can significantly reduce the magnitude of the vibration. Also, the magnitude can be reduced if the natural frequency can be shifted away from the forcing frequency by changing the stiffness or mass of the system. If the system cannot be changed, perhaps
3465-587: Is undesirable, wasting energy and creating unwanted sound . For example, the vibrational motions of engines , electric motors , or any mechanical device in operation are typically unwanted. Such vibrations could be caused by imbalances in the rotating parts, uneven friction , or the meshing of gear teeth. Careful designs usually minimize unwanted vibrations. The studies of sound and vibration are closely related (both fall under acoustics ). Sound, or pressure waves , are generated by vibrating structures (e.g. vocal cords ); these pressure waves can also induce

It was released as an optional accessory for the Mega Drive (Genesis) in 1993 and could read the player's physical movements using full-body motion tracking. It was a commercial failure due to its "unwieldiness and inaccuracy". Motion controllers became more widely distributed with

Other "response" points may experience higher vibration levels (resonance) or lower vibration level (anti-resonance or damping) than the control point(s). It is often desirable to achieve anti-resonance to keep a system from becoming too noisy, or to reduce strain on certain parts due to vibration modes caused by specific vibration frequencies. The most common types of vibration testing services conducted by vibration test labs are sinusoidal and random. Sine (one-frequency-at-a-time) tests are performed to survey

The force applied to the mass by the spring is proportional to the amount the spring is stretched "x" (assuming the spring is already compressed due to the weight of the mass). The proportionality constant, k, is the stiffness of the spring and has units of force/distance (e.g. lbf/in or N/m). The negative sign indicates that

Vibration can be desirable: for example, the motion of a tuning fork , the reed in a woodwind instrument or harmonica , a mobile phone , or the cone of a loudspeaker . In many cases, however, vibration
8019-476: The play space. Oculus later switched to an "inside-out" tracking system for Oculus Quest and Rift S , where the controllers are tracked by cameras in the headset itself. The Nintendo Switch hybrid home/portable console and its included Joy-Con controllers feature 6DOF sensors in each controller in the pair as well as in the main body of the console. The optional Nintendo Switch Pro Controller and Poké Ball Plus controllers also feature 6DOF sensors. In
8118-419: The same frequency, f , of the applied force, but with a phase shift ϕ . {\displaystyle \phi .} The amplitude of the vibration “X” is defined by the following formula. Where “r” is defined as the ratio of the harmonic force frequency over the undamped natural frequency of the mass–spring–damper model. The phase shift, ϕ , {\displaystyle \phi ,}
8217-559: The sensors are specialized integrated circuits . The following items are examples of current and historical methods of tracking motion. Inertial Measurement Units (IMUs) are used to detect the rate of change in rotation using gyroscopes and change in speed using accelerometers. These are often found together on the same integrated circuit and can be used together to provide six degrees of freedom ( 6DOF ) tracking. Image sensors are used in conjunction with computer vision and are placed in locations such as on handheld or worn devices or in
8316-494: The stand-alone controller will also include the demo disk for a limited time. In Europe, a bundle will be released with a demo disc. In Asian countries outside Japan such as Singapore , the bundles are available with the games Sports Champions , Start the Party! , and Kung Fu Rider . PlayStation Move stems from early work on the EyeToy , a webcam-based controller for the PlayStation 2 conceived in 1999 and released in 2003. Early in
8415-428: The structural response of the device under test (DUT). During the early history of vibration testing, vibration machine controllers were limited only to controlling sine motion so only sine testing was performed. Later, more sophisticated analog and then digital controllers were able to provide random control (all frequencies at once). A random (all frequencies at once) test is generally considered to more closely replicate
8514-415: The swing get higher and higher. As in the case of the swing, the force applied need not be high to get large motions, but must just add energy to the system. The damper, instead of storing energy, dissipates energy. Since the damping force is proportional to the velocity, the more the motion, the more the damper dissipates the energy. Therefore, there is a point when the energy dissipated by the damper equals
8613-446: The system vibrates once set in motion by an initial disturbance. Every vibrating system has one or more natural frequencies that it vibrates at once disturbed. This simple relation can be used to understand in general what happens to a more complex system once we add mass or stiffness. For example, the above formula explains why, when a car or truck is fully loaded, the suspension feels "softer" than unloaded—the mass has increased, reducing
8712-417: The system “rings” down over time. What is often done in practice is to experimentally measure the free vibration after an impact (for example by a hammer) and then determine the natural frequency of the system by measuring the rate of oscillation, as well as the damping ratio by measuring the rate of decay. The natural frequency and damping ratio are not only important in free vibration, but also characterize how
8811-444: The technologies needed for motion controllers are often used together in smartphones to provide a variety of functions, including for mobile applications to use them as motion controllers. Motion controllers have used a variety of different sensors in different combinations to detect and measure movements, sometimes as separate inputs and sometimes together to provide a more precise or more reliable input. In modern devices most of
8910-516: The tentative name, but by this time media attention had shifted to rumored final names. In September 2009, statements in two unconnected interviews at the Tokyo Game Show led to speculation that the controller may be referred to by developers as the "Sphere". In December, a brief reference to the motion controller as "Gem" by Electronic Arts CEO John Riccitiello during a media industry conference presentation prompted an admission by Sony that "Gem"
9009-514: The three teams coming together. This was the start of a new form of development at Sony, where hardware had previously been developed separately from software teams and later delivered along with technical documentation for software teams to get to grips with themselves; this move was continued with the development of the PlayStation Vita and PlayStation 4. The motion controller was revealed at Sony's E3 2009 press conference on 2 June 2009, with
9108-603: The time Sony was already rumored to be in the design phase of a supplementary controller akin to that of the Nunchuk controller for the Wii Remote . In January 2010, Sony announced a revised release target, stating instead that the motion controller would launch in Q3/Q4 of 2010. On March 10, Sony revealed the official name and logo at the Game Developers Conference , showcasing the final motion controller design, and unveiling
9207-729: The use of its gyroscope as a pointer control. Its motion tracking features would later be adapted for the Steam Deck . A wave of virtual reality headsets released in the 2010s adopted forms of 6DOF motion controllers; the HTC Vive was bundled with wand-like controllers, while controllers known as Oculus Touch were released initially as an optional accessory for Oculus Rift in December 2016, and became part of its standard equipment in July 2017. Both controllers are tracked using infrared emitters placed in
9306-413: The user environment captured by the camera, the system dynamically selects an orb color that can be distinguished from the rest of the scene. The colored light serves as an active marker, the position of which can be tracked along the image plane by the camera. The uniform spherical shape and known size of the light also allows the system to simply determine the controller's distance from the camera through
9405-525: The vibration environment, fatigue life, resonant frequencies or squeak and rattle sound output ( NVH ). Squeak and rattle testing is performed with a special type of quiet shaker that produces very low sound levels while under operation. For relatively low frequency forcing (typically less than 100 Hz), servohydraulic (electrohydraulic) shakers are used. For higher frequencies (typically 5 Hz to 2000 Hz), electrodynamic shakers are used. Generally, one or more "input" or "control" points located on
9504-412: The vibration of structures (e.g. ear drum ). Hence, attempts to reduce noise are often related to issues of vibration. Machining vibrations are common in the process of subtractive manufacturing . Free vibration or natural vibration occurs when a mechanical system is set in motion with an initial input and allowed to vibrate freely. Examples of this type of vibration are pulling a child back on
9603-458: Was an early code name for the controller. In January 2010, video game blog VG247 reported that Sony had named its PS3 motion control platform "Arc". The name was observed to liken the controller's glowing orb to the charged sphere of a Tesla coil or a plasma globe electrode. The report was supported by evidence emerging in the following weeks, including a registration of the playstationarc.com domain name to SCE dated October 2009 (shortly after
9702-436: Was an early unreleased VR device with built-in motion tracking, first announced in 1991. Its sensors tracked the player's movement and head position. Another early example is the 2000 light gun shooter arcade game Police 911 , which used motion tracking technology to detect the player's movements, which are reflected by the player character within the game. The Atari Mindlink was an early proposed motion controller for
9801-410: Was reported that Sony submitted Japanese trademark application filing for "PlayStation Arc". A week later on March 8, Sony was reportedly considering a hasty renaming due to a trademark held by competitor Microsoft for its Arc-brand PC accessories, which could present trademark conflicts. On March 9, Sony submitted a European trademark filing for "PlayStation Move", which was announced as the official name
