Exergaming or exer-gaming (a portmanteau of "exercise" and "gaming") is a term used for video games that are also a form of exercise. Exergaming relies on technology that tracks body movement or reaction. The genre has been credited with upending the stereotype of gaming as a sedentary activity, and promoting an active lifestyle. Exergames are seen as evolving from technology changes aimed at making videogames more fun.

History

The genre's roots can be found in games released in the late eighties, including ''Power Pad'' (or ''Family Trainer'') for the Nintendo Entertainment System (NES) and ''Foot Craz'' for the Atari 2600, although both had limited success. Konami's ''Dance Dance Revolution'' was cited as one of the first major successes of exergaming; when it was ported from the arcade to PlayStation, it sold over three million copies. In the 2000s, a number of devices and games have used the exergame style to much success: the EyeToy camera has sold over ten million units, while Nintento's Wii Fit has sold in excess of 21 million copies. By June 2009, health games were generating revenues of $2 billion, largely due to ''Wii Fit's'' 18.22 million sales at the time. The term exergaming entered the ''Collins English Dictionary'' in 2007.

The genre has been mooted as a way to improve users' health through exercise, but few studies have been undertaken to measure the health benefits. Smaller trials have yielded mixed results and have shown that the respective traditional methods of exercise are superior to their video game equivalents.

1980s

Exergaming contains elements that were developed in the virtual reality community during the 1980s. The pioneer in this area was Autodesk, which developed two systems, the ''HighCycle'' and ''Virtual Racquetball''. The ''HighCycle'' was an exercise bike that a user would pedal through a virtual landscape. If the user pedaled fast enough, the virtual bike would take off and fly over the landscape. ''Virtual Racquetball'' tracked the position and orientation of an actual racquet that was used to hit a virtual ball in a virtual environment. This environment was shared with another user equipped with another tracked racquet, allowing the two users to play each other over phone lines. In both systems, the users could wear the ''VPL eyephones'', an early Head-mounted display (HMD), that would provide more immersion for the user.

The first true attempt at what would later be called Exertainment was the Atari ''Puffer'' project (1982). This was an exercise bike that would hook up to an Atari 400/800 or 5200 system. Forward speed was controlled by pedaling while steering and additional gameplay was handled by a handlebar-mounted Gamepad. The machine was nearly ready for production with several games (''Tumbleweeds'' and ''Jungle River Cruise'') when Atari declared bankruptcy and the Puffer project was abandoned. Nintendo also dabbled in this space with the Power Pad in the late 1980s.

The first exergaming system released to the market was the 1986 ''Computrainer''. Designed as a training aid and motivational tool, the ''Computrainer'' allowed users to ride through a virtual landscape generated on a Nintendo NES, while monitoring data such as power output and pedaling cadence. The product had a price that was far too high to be considered as an entertainment product, but was affordable by dedicated athletes. The product continues to this day, where it now runs using Microsoft Windows compatible software with extensive graphic and physiological capabilities.

Also released for the NES in 1986 was the Family Trainer, which focused on entertainment rather than exercise.

About the same time as the Computrainer, Concept II introduced a computer attachment for their rowing machine. This has become their ''eRow'' product and is used for both individual motivation as well as competition in "indoor rowing leagues"

1990s

During the 1990s, there was a surge of interest in the application of "virtual reality" technologies to high-end gym equipment. Life Fitness and Nintendo partnered to produce the ''Exertainment'' System; Precor had an LCD-based bike product, and Universal had several CRT-based systems. The Netpulse system provided users with the ability to browse the web while exercising. Fitlinxx introduced a system that used sensors attached to weight machines in order to provide automated feedback to users.

The most sophisticated of these entries was the Tectrix ''VR Bike''. Developed originally by CyberGear Inc., The VR Bike allowed users to pedal through a number of virtual environments as well as engage in single and multiplayer games. It was joined later by the ''VR Climber''.The VR Bike software is now distributed alongside Trixter bikes.

Three issues combined to ensure the failure of these systems in the marketplace. First, they were significantly more expensive than the equivalent models that did not have all the additional electronics. Second, they were harder to maintain, and were often left broken. Lastly the additional expertise required to operate the software was often intimidating to the users, who shied away from the machines out of fear that they would look foolish while trying to master the machine.

Until 1998, nothing significant happened in the field of videogame exercise. Hardware was still too expensive for the average home consumer, and the health clubs were gun-shy about adopting any new technology. As high-performance game console capabilities improved and prices fell, manufacturers once more started to explore the fitness market.

In 1998, Konami's Dance Dance Revolution was released. It was highly effective—exercise-wise—and very cost effective and so brought exergaming into the mainstream.

2000s

In 2000, UK startup Exertris introduced an interactive gaming bike to the commercial fitness market.

Exergaming came to the mass media attention at the Consumer Electronics Show when Bill Gates showcased the Exertris Interactive Gaming Bike in 2003, and the following year the same show hosted a pavilion dedicated to video game technology that also worked as sports and exercise equipment.

The 2005 release of the EyeToy: Kinetic, brought the first—multi-function—exergame hardware into the home market. Making the players physical movements into the game's controller. 2006 Saw the launch of Gamercize, combining traditional fitness equipment with games consoles. The minimalist approach allows game play to continue only when exercising, turning all game titles into potential exergames.

Nintendo's Wii in 2006 brought acceleration detection with the Wii Remote. In late 2007, Nintendo released the exergame Wii Fit, which utilized a new peripheral, the Wii Balance Board. Various approaches to exergames have been documented and compared by VideoJug in an information film.

The PCGamerBike appeared at CES in 2007 where it received an Honoree Award. It differs from other exergaming devices in that its pedal motion can be mapped to any key on the keyboard. It also has a optical encoder which detects forward and reverse pedal motion. The Fisher-Price Smart Cycle was another entry in the field.

Other examples of exergaming products include: Cyber coach, NeoRacer, Gymkids exercise equipment with interactive technology, some Wii titles such as EA Sports Active, Cybex TRAZER, Powergrid Fitness Kilowatt, Lightspace Play Floor, PlayMotion, Yourself!Fitness, Expresso Fitness S2, i.play, VEQTOR Sport Trainer and Sportwall.

Effectiveness

The effectiveness of maintaining interest in exercise using traditional fitness machines has been examined with Gamercize and found to be six times more sustainable than exercise alone.

While the Wii has been seen as being more physically demanding than sedentary game consoles, a study published in the British Medical Journal found that while playing the Wii uses significantly more energy than playing sedentary computer games, the energy used when playing active Wii games is not of high enough intensity to contribute towards the recommended daily amount of exercise in children.

Benefits of exercise on mental ability and productivity are in the early stages of research, but indications from using Gamercize with a computer have been reported as providing a 17% productivity improvement. Combining cardiovascular exercise and balance practice has been shown to increase academic success among students in grades K-12. According to the 2009 Active Healthy Kids Canada Report Card on PhysicalActivity for Children and Youth, children who are physically active perform better in school than those who are not. Interestingly, academic performance improves even when academic learning time is reduced to allow time for physical activity. ,

Electronic Arts commissioned a 2010 study by the University of Wisconsin which found that EA Sports Active passed fitness guidelines for an "effective workout" put forth by the American College of Sports Medicine.

Design trends

When making an exergaming system, the manufacturer of a consumer product must make the decision as to whether the system will be usable with off-the-shelf games or if custom software must be written for it. Because it takes longer for a user to move their entire body in response to stimulation from the game, it is often the case that dedicated software must be written for the game to playable. An example of this is Konami's ''Dance Dance Revolution''. Though designed to be played by users moving about on a specially designed dancepad, that game can alternatively be played by pushing buttons with one's fingers using a standard hand-held gamepad. When played with the dancepad at higher levels the game can be quite challenging (and physically exhausting), but if the game is played using the buttons on the hand controller, none of the sequences are physically limited.

Newer systems such as Xbox 360, PlayStation 3 and Wii use alternative input devices such as the Kinect and PlayStation Move. The Move uses image analysis to extract the motion of the user against a background and uses these motions to control the character in the game. A specifically designed exercise game ''Kinetic'', superimposes animated objects to be punched, kicked, or otherwise interacted with over a video image of the user. The Wii and Playstation3 both incorporate motion sensors such as accelerometers and gyroscopes into the hand-held controllers that are used to direct behaviors within the game.

Research projects such as Exertion Interfaces that investigate the design aspects of these games explore how the technological augmentation that comes with the digital gameplay component can be nurtured for additional benefits, such as utilizing the social power of exercising together even though players are connected only over a network or scaling the amount of players, enabling novel exercise experiences not available without the technological augmentation.

Exergame resellers have developed fitness centers and specialist room designs with programmes that focus entirely on creating environments for young people using exergaming for fitness. Exergaming can be found as part of larger fitness facilities or dedicated gyms.
