Press Release: Carnegie Mellon Develops Touchscreen Technology That Distinguishes Taps by Different Parts of Finger

TapSense Could Enhance Touch Interaction on Smartphones and Tablet Computers

PITTSBURGH—Smartphone and tablet computer owners have become adept at using finger taps, flicks and drags to control their touchscreens. But Carnegie Mellon University researchers have found that this interaction can be enhanced by taking greater advantage of the finger's anatomy and dexterity.
By attaching a microphone to a touchscreen, the CMU scientists showed they can tell the difference between the tap of a fingertip, the pad of the finger, a fingernail and a knuckle. This technology, called TapSense, enables richer touchscreen interactions. While typing on a virtual keyboard, for instance, users might capitalize letters simply by tapping with a fingernail instead of a finger tip, or might switch to numerals by using the pad of a finger, rather toggling to a different set of keys.
Another possible use would be a painting app that uses a variety of tapping modes and finger motions to control a pallet of colors, or switch between drawing and erasing without having to press buttons.
"TapSense basically doubles the input bandwidth for a touchscreen," said Chris Harrison, a Ph.D. student in Carnegie Mellon's Human-Computer Interaction Institute (HCII). "This is particularly important for smaller touchscreens, where screen real estate is limited. If we can remove mode buttons from the screen, we can make room for more content or can make the remaining buttons larger."
TapSense was developed by Harrison, fellow Ph.D. student Julia Schwarz, and Scott Hudson, a professor in the HCII. Harrison will discuss the technology today (Oct. 19) at the Association for Computing Machinery's Symposium on User Interface Software and Technology in Santa Barbara, Calif. A video demonstrating the technology's capabilities and possible applications can be viewed at:

"TapSense can tell the difference between different parts of the finger by classifying the sounds they make when they strike the touchscreen," Schwarz said. An inexpensive microphone could be readily attached to a touchscreen for this purpose. The microphones already in devices for phone conversations would not work well for the application, however, because they are designed to capture voices, not the sort of noise that TapSense needs to operate.
The technology also can use sound to discriminate between passive tools (i.e., no batteries) made from such materials as wood, acrylic and polystyrene foam. This would enable people using styluses made from different materials to collaboratively sketch or take notes on the same surface, with each person's contributions appearing in a different color or otherwise noted.
The researchers found that their proof-of-concept system was able to distinguish between the four types of finger inputs with 95 percent accuracy, and could distinguish between a pen and a finger with 99 percent accuracy.

An artist's impression of a POET

2010-07-12T10:25:00.000+05:30

An artist always thinks about an imaginary world and the artists way is like that .A poet is an emalgamation of an art as well as beauty of the literature..I somehow think of similarities between the same.A poets thoughts are pertaining to a rolling picture where as an artists thoughts are fixed unmovable picture ..A poet takes the reader to an imaginary world of happenings where the mind becomes a screen and the picture goes like a rolling screen where as an artist makes the same picture and makes them into the reality which is painted in a piece of paper ..I somehow thought about this that both the poet and the artist lives in an imaginary world turning the imaginary to imaginary where as the latter changes imaginary into a fixed real ..the two sides are really a matter of thought and no one is mighter than the other....

Cause for our mother earth

2010-07-02T23:08:00.000+05:30

Natures endowned beauty lies in the eyes of the viewer..as a famous quote says
our mother natures great wonders are sometimes make us exclaimed of our existence in the earth but we go on depleting its resources and we go on damaging
the beauty of our mother earth..we have so far had created pollution every where in the earth be it in air,water, soil...and we have not even left the gound water which is the source of pure water..we have made all these and so we are repenting on its ill effects such as less rainfall, less oxygen,less fresh water for drinking and less of resource of fossil and fuel..and moreover created a bit setback which we cant save that is global warming..our mother earth is bleeding by these and what we are doing for it ?its logical to think..fighting in the summit of global warming in the sake of development and we are just talking and talking.
