Possibility of Gestures Control
Abstract
Back in to 1990 I was a child; playing games in front of computer by keyboard is one of my happy times. Remember few years’ later joystick revolution the control function of gaming. As technology getting develop as faster, today we can control devices without touch it! It’s not just touch-free to playing games; also we can use gesture control on many field, education, automobile, consumer elections, and even medical devices.
Gesture control or known as Gesture Command, is getting popular in use on Computers, Communications, and Consumer products. The mystery of control these devices without touch is using smart 3D sensor. Past part are some introducing about 3D sensor.
Past
In the past decade, gesture-control technologies develop very well by micro-chips, from start by camera face capture function. Use “Time-Of-Flight (TOF)” which invented by William E. Stephens, in 1946. After that grateful invented, it makes robust in today 3D sensing possible in an ordinary CMOS process.
The applied of “TOF” is use an apparatus sends out a short optical pulse and measures the time until a reflected portion of the pulse is monitored.
Typically used for large distances such as hundreds of meters or many kilometers. Using advanced techniques (involving high-quality telescopes, and photo detection, etc.). It is possible to measure e.g. the distance between the Earth and the Moon with an accuracy of a few centimeters, or to obtain a precise profile of a dam.
Present
We already have Gesture-Control devices application on many areas. In CONSUMER ELECTRONICS – now like TV by Hitachi [1],[2] ; we can control by our hand, and don’t need to use that remote controller. Also we have
In GAMING- there are more and more games support gesture control, they can use 3D sensor to archive following situation.
Game player Controls – A camera in the console interprets user commands to control the game. In these implementations, there is typically no live video of the user on the screen. The user actions simply control the game with very low latency and no concerns about lighting or background motion. Typical motions might include turning the user’s head left or right to pan the game display to that direction. [3]Vodpod videos no longer available.
Body Kinetic Games – The movement of the user directly translates into character actions on the screen. The user watches the screen as he interacts with the game and his actions directly relate to the application flow. Low latency is important. There are two classes of games in this category – follow-along games like “Simon Says” and skeletal tracking games, like air boxing, air guitar, or bowling. [4]
In Automotive-
Installation 3D sensor in car, its can analytics the distance from our car to the others, makes sure we all drive in the safe distance.
In Health
We can use gesture control for our patients, such as use a kind of games to make them recover their body or doing excise in game.
Future
Apple’s iPhone successful by its capacitive touch screen and Nintendo’s Wii kill game market again with its accelerometer. Smart 3D sensor will range into more and more devices in future. According to Dan Saffer, who wrote the book “Designing Gestural Interfaces (O’Reilly Publishing, 2008)” and a founder and principal at Kicker Studio, gesture controls have the potential to revolutionize the way we use TVs and PCs – as well as many other products.
“The sophisticated technology provided with Canesta’s 3-D sensor chips are proving to be the missing link to make this happen on a mass market basis," he says.
Also here are some possibilities of gesture control in future.
For education
In nearly future we can use gesture control devices to record our move and use camera captures the user movements for analysis and playback. The analysis is useful for teaching like karate, dancing and so on. The user performs the activity and then reviews the results on a monitor.
Since average age of population getting raise in world here are some thing cool For Health areas [5]. A product call “IREX® (Interactive Rehabilitation and Exercise System)” can help Patients in a full-body virtual world, they can interact with on-screen images and objects, designed to enhance the sense of “presence” for the patient. Real-time audio and visual feedback further stimulates the patient, resulting in improved motivation and effort in rehabilitation exercises.
In conclusion, gesture control seems can change our way of life in the future. Although we still need to get used to that non-feeling control, and maybe if there are so many gesture control devices in one room, how to make sure if we try to change the TV channel would also turn on our music player or not? It’s good to see from the video one day we getting old. Our life won’t feel boring cause gesture control.
