... in an information-rich world, the wealth of information means a dearth of something else: a scarcity of whatever it is that information consumes. What information consumes is rather obvious: it consumes the attention of its recipients. Hence a wealth of information creates a poverty of attention, and a need to allocate that attention efficiently among the overabundance of information sources that might consume it.

-- Herbert Simon in "Computers, Communications and the Public Interest," 1971

Murase, Taichi, Moteki, Atsunori, Suzuki, Genta, Nakai, Takahiro, Hara, Nobuyuki and Matsuda, Takahiro (2012): Gesture keyboard with a machine learning requiring only one camera. In: Proceedings of the 2012 Augmented Human International Conference 2012. p. 29.

In this paper, the authors propose a novel gesture-based virtual keyboard (Gesture Keyboard) that uses a standard QWERTY keyboard layout, and requires only one camera, and employs a machine learning technique. Gesture Keyboard tracks the user's fingers and recognizes finger motions to judge keys input in the horizontal direction. Real-Adaboost (Adaptive Boosting), a machine learning technique, uses HOG (Histograms of Oriented Gradients) features in an image of the user's hands to estimate keys in the depth direction. Each virtual key follows a corresponding finger, so it is possible to input characters at the user's preferred hand position even if the user displaces his hands while inputting data. Additionally, because Gesture Keyboard requires only one camera, keyboard-less devices can implement this system easily. We show the effectiveness of utilizing a machine learning technique for estimating depth.

Murase, Taichi, Moteki, Atsunori, Ozawa, Noriaki, Hara, Nobuyuki, Nakai, Takehiro and Fujimoto, Katsuhito (2011): Gesture keyboard requiring only one camera. In: Proceedings of the 2011 ACM Symposium on User Interface Software and Technology 2011. pp. 9-10.

In this paper, we propose a novel gesture-based virtual keyboard (Gesture Keyboard) of QWERTY key layout requiring only one camera. Gesture Keyboard tracks the user's fingers and recognizes gestures as the input, and each virtual key of it follows a corresponding finger. Therefore, it is possible to input characters at the user's preferred hand position even if displacing hands during inputting. Because Gesture Keyboard requires only one camera to obtain sensor information, keyboard-less devices can feature it easily.
