The Thrilling Potential Of Sixth Sense Technology

The Thrilling Potential Of Sixth Sense Technology


We grew up interacting with the physical objects around us. There is an enormous number of them that we use every day. Unlike most of our computing devices, these objects are much more fun to use. When you talk about objects, one other thing automatically comes attached to that thing, and that is gestures: how we manipulate these objects, how we use these objects in everyday life.

The Thrilling Potential Of Sixth Sense Technology








We use gestures not only to interact with these objects, but we also use them to interact with each other. A gesture of " Namaste!", maybe, to respect someone, or maybe, in India I don't need to teach a kid that this means" four runs" in cricket. It comes as a part of our everyday learning. So, I am very interested, from the beginning, how our knowledge about everyday objects and gestures, and how we use these objects, can be leveraged to our interactions with the digital world. Rather than using a keyboard and mouse, why can I not use my computer in the same way that I interact with the physical world? So, I started this exploration around eight years back, and it literally started with a mouse on my desk. Rather than using it for my computer, I actually opened it. Most of you might be aware that, in those days, the mouse used to come with a ball inside, and there were two rollers that actually guide the computer where the ball is moving, and, accordingly, where the mouse is moving. So, I was interested in these two rollers, and I actually wanted more, so I borrowed another mouse from a friend --never returned to him --and I now had four rollers. Interestingly, what I did with these rollers is, basically, I took them off of these mouses and then put them in one line. It had some strings and pulleys and some springs.

    Limitations of Terzaghi Theory

    Limitations of Terzaghi Theory The value of the coefficient of consolidation has been assumed to be constant.  The distance d of the drainage path cannot be measured accurately in the field. The thickness of the deposit is generally variable, and an average value has to be estimated.  There is sometimes difficulty 1n locating the drainage face, sometimes thin previous seams that can act as good drainage face are missed in the boring operations. The equation is based on the assumption that the consolidation is one-dimensional. In the field, the consolidation is generally 3-dimensional. The lateral drainage may have a significant effect on the time rate of consolidation. The initial consolidation and secondary consolidation have been neglected. Sometimes these form an important part of the total consolidation. In actual practice, the pressure distribution may be far from linear or uniform. Read More Muller-Breslau principle

    Price Guard Wire Method

    Price Guard Wire Method Some form of  Price Guard Wire Method  is generally used to eliminate the errors caused by leakage currents over insulation. Fig. 3.14 illustrates the operation of This Method. In fig 3.14(a), a high resistance mounted on a piece of insulating material is measured by the ammeter voltmeter method. The micro-ammeter measures the sum of the current through the resistor (IR) and the current through the leakage path around the resistor. The measured value of resistance computed from the readings indicated on the voltmeter and the microammeter, will not be a true value but will be in error.   Figure 3.14 Application of  guard  circuit for measurement of high resistance In fig, 3.14 (b), the  guard  terminal has been added to the resistance terminal block. The  guard  terminal surrounds the resistance terminal entirely and is connected to the battery side of the micro-ammeter. The leakage current IL now bypasses t

    Negative Booster

    Negative booster A negative booster is employed to conform to the regulation that the potential difference between any two points of the rail return shall not exceed 7 V. Two boosters, positive and negative, are used which are mechanically coupled together and driven by a DC motor. The positive booster is connected to the trolley wire (near the generating station) and the negative booster (separately excited) is connected to the track rail.  The 'positive booster' adds voltage to the line while the 'negative booster lowers the potential of the point it is connected to. As we go along the trolley wire away from the generating station/sub-station, the potential drop increases, and the voltage of the trolley wire falls. Since the current returns via the track rail points away from the generating station acquire high potentials. This potential is brought down by the negative boost provided by the negative booster. When the load is sufficiently far away from the generating stati
