Having cold hands does not make it unuseable.
No it has to do with the flow of electricity in your body.
-.- if you touch your iphone to a lightbulb when its on, nothing will happen. Its the static/nerve electricty.
Or atleast thats what i think :biggrin::350:
[code]There are a number of types of touchscreen technology.
[edit] Resistive
Main article: Resistive touchscreen
A resistive touchscreen panel is composed of several layers, the most important of which are two thin, metallic, electrically conductive layers separated by a narrow gap. When an object, such as a finger, presses down on a point on the panel's outer surface the two metallic layers become connected at that point: the panel then behaves as a pair of voltage dividers with connected outputs. This causes a change in the electrical current which is registered as a touch event and sent to the controller for processing. Resistive touchscreens can also support Multitouch. [1]
[edit] Surface acoustic wave
Surface acoustic wave (SAW) technology uses ultrasonic waves that pass over the touchscreen panel. When the panel is touched, a portion of the wave is absorbed. This change in the ultrasonic waves registers the position of the touch event and sends this information to the controller for processing. Surface wave touchscreen panels can be damaged by outside elements. Contaminants on the surface can also interfere with the functionality of the touchscreen.[2]
[edit] Capacitive
Main article: capacitive sensing
A capacitive touchscreen panel is a sensor typically made of glass coated with a transparent conductor such as indium tin oxide (ITO).[3][4] This type of sensor is basically a capacitor in which the plates are the overlapping areas between the horizontal and vertical axes in a grid pattern. Since the human body also conducts electricity, a touch on the surface of the sensor will affect the electric field and create a measurable change in the capacitance of the device. Like the stylus used in the defunct CED video disc, these sensors work on proximity of the conductive medium (finger), and do not have to be directly touched to be triggered. It is a durable technology that is used in a wide range of applications including point-of-sale systems, industrial controls, and public information kiosks. It has a higher clarity than Resistive technology, but it only responds to finger contact and will not work with a gloved hand or pen stylus unless the stylus is conductive. Capacitive touchscreens can also support Multitouch. Examples include Apple Inc.'s iPhone and iPod Touch, HTC's G1 & HTC Magic, Palm Inc.'s Palm Pre and Palm Eos and more recently the LG KM900 Arena, Microsoft's Zune HD, Sony Walkman X series and Sony Ericsson's Aino.
[edit] Projected capacitance
Projected Capacitive Touch (PCT) technology is a type of capacitive technology which involves the relationship between an XY array of sensing wires embedded within two layers of non-metallic material, and a third object. In touchscreen applications the third object can be a human finger. Projected capacitance creates an electrostatic field above the sensing surface to determine inputs. This format requires the use of patterned ITO and requires no calibration.[5] Capacitance forms between the user’s fingers and projected capacitance from the sensing wires. A touch is made, precisely measured, then passed on to the controller system which is connected to a computer running a software application. This will then calculate how the user’s touch relates to the computer software. PCT screens enjoy the benefits of responding accurately to both fingers and styli.
Visual Planet’s ViP Interactive Foil is an example of a product that uses PCT technology. This technology allows a gloved hand to make the touch, resulting in PCT technology now being common in external "through window" touch applications (i.e. those where no direct physical contact with the touchscreen is made).
[edit] Infrared
Conventional optical-touch systems use an array of infrared (IR) light-emitting diodes (LEDs) on two adjacent bezel edges of a display, with photosensors placed on the two opposite bezel edges to analyze the system and determine a touch event. The LED and photosensor pairs create a grid of light beams across the display. An object (such as a finger or pen) that touches the screen interrupts the light beams, causing a measured decrease in light at the corresponding photosensors. The measured photosensor outputs can be used to locate a touch-point coordinate.
Widespread adoption of infrared touchscreens has been hampered by two factors: the relatively high cost of the technology compared to competing touch technologies and the issue of performance in bright ambient light. This latter problem is a result of background light increasing the noise floor at the optical sensor, sometimes to such a degree that the touchscreen’s LED light cannot be detected at all, causing a temporary failure of the touch screen. This is most pronounced in direct sunlight conditions where the sun has a very high energy distribution in the infrared region.
However, certain features of infrared touch remain desirable and represent attributes of the ideal touchscreen, including the option to eliminate the glass or plastic overlay that most other touch technologies require in front of the display. In many cases, this overlay is coated with an electrically conducting transparent material such as ITO, which reduces the optical quality of the display. This advantage of optical touchscreens is extremely important for many device and display vendors since devices are often sold on the perceived quality of the user display experience.
Another feature of infrared touch which has been long desired is the digital nature of the sensor output when compared to many other touch systems that rely on analog-signal processing to determine a touch position. These competing analog systems normally require continual re-calibration, have complex signal-processing demands (which adds cost and power consumption), demonstrate reduced accuracy and precision compared to a digital system, and have longer-term system-failure modes due to the operating environment.
Finally, infrared touch is not capable of multi-touch as a result of the mode of operation being one in which lines of light are disrupted. Thus for two points, two beams would be disrupted on both the horizontal and vertical axes each, allowing for a total of four potential point locations. This ambiguity makes infrared unsuitable for multi-touch applications.
Neonode has taken conventional infrared touch technology, using LEDs and photodiodes, and essentially miniaturized it and reduced the cost for use in handheld devices. In addition to using the technology in its own N2 cell phone, Neonode is also marketing it to other device makers.
[edit] Strain gauge
In a strain gauge configuration, also called force panel technology, the screen is spring-mounted on the four corners and strain gauges are used to determine deflection when the screen is touched.[6] This technology has been around since the 1960s but new advances by Vissumo and F-Origin have made the solution commercially viable.[7] It can also measure the Z-axis and the force of a person's touch. Typically used in exposed public systems such as ticket machines due to their resistance to vandalism.[8]
[edit] Optical imaging
A relatively-modern development in touchscreen technology, two or more image sensors are placed around the edges (mostly the corners) of the screen. Infrared backlights are placed in the camera's field of view on the other sides of the screen. A touch shows up as a shadow and each pair of cameras can then be triangulated to locate the touch or even measure the size of the touching object (see visual hull). This technology is growing in popularity, due to its scalability, versatility, and affordability, especially for larger units.
[edit] Dispersive signal technology
Introduced in 2002 by 3M, this system uses sensors to detect the mechanical energy in the glass that occurs due to a touch. Complex algorithms then interpret this information and provide the actual location of the touch.[9] The technology claims to be unaffected by dust and other outside elements, including scratches. Since there is no need for additional elements on screen, it also claims to provide excellent optical clarity. Also, since mechanical vibrations are used to detect a touch event, any object can be used to generate these events, including fingers and stylus. A downside is that after the initial touch the system cannot detect a motionless finger.
[edit] Acoustic pulse recognition
This system, developed by Tyco International's Elo division, uses more than two piezoelectric transducers located at some positions of the screen to turn the mechanical energy of a touch (vibration) into an electronic signal.[10] The screen hardware then uses an algorithm to determine the location of the touch based on the transducer signals. This process is similar to triangulation used in GPS. The touchscreen itself is made of ordinary glass, giving it good durability and optical clarity. It is usually able to function with scratches and dust on the screen with good accuracy. The technology is also well suited to displays that are physically larger. As with the Dispersive Signal Technology system, after the initial touch, a motionless finger cannot be detected.[/code]
