How Does a Touchscreen Work???

A basic touchscreen has three main components: a touch sensor, a controller, and a software driver. The touchscreen is an input device, so it needs to be combined with a display and a PC or other device to make a complete touch input system.





1. Touch Sensor
A touch screen sensor is a clear glass panel with a touch responsive surface. The touch sensor/panel is placed over a display screen so that the responsive area of the panel covers the viewable area of the video screen. There are several different touch sensor technologies on the market today, each using a different method to detect touch input. The sensor generally has an electrical current or signal going through it and touching the screen causes a voltage or signal change. This voltage change is used to determine the location of the touch to the screen.

2. Controller
The controller is a small PC card that connects between the touch sensor and the PC. It takes information from the touch sensor and translates it into information that PC can understand. The controller is usually installed inside the monitor for integrated monitors or it is housed in a plastic case for external touch add-ons/overlays. The controller determines what type of interface/connection you will need on the PC. Integrated touch monitors will have an extra cable connection on the back for the touchscreen. Controllers are available that can connect to a Serial/COM port (PC) or to a USB port  (PC or Macintosh). Specialized controllers are also available that work with DVD players and other devices.

3. Software Driver
The driver is a software update for  the PC system that allows the touchscreen and computer to work together. It tells  the computer operator how to interpret the touch event information that is sent from the controller. Most touch screen drivers today are a mouse-emulation type driver. This makes touching the screen the same as clicking your mouse at the same location on the screen. This allows the touchscreen to work with existing software and allows new applications to be developed without the need for touchscreen specific programming. Some equipment such as thin client terminals, DVD players, and specialized computer systems either do not use software drivers or they have their own built-in touch screen driver.

Touchscreens Add-ons and Integrated Touchscreen Monitors

We offer two main types of touchscreen products, touchscreen add-ons and integrated touchscreen monitors. Touchscreen add-ons are touchscreen panels that hang over an existing computer monitor. Integrated touchscreen monitors are computer displays that have the touchscreen built-in. Both product types work in the same way, basically as an input device like a mouse or trackpad.

Touchscreens As Input Device

All of the touchscreens that we offer basically work like a mouse. Once the software driver for the touchscreen is installed, the touchscreen emulates mouse functions. Touching the screen is basically the same as clicking your mouse at the same point at the screen. When you touch the touchscreen, the mouse cursor will move to that point and make a mouse click. You can tap the screen twice to perform a double-click, and you can also drag your finger across the touchscreen to perform drag-and-drops. The touchscreens will normally emulate left mouse clicks. Through software, you can also switch the touchscreen to perform right mouse clicks

RANN review

RANN is truly a well-made film. No two opinions on that.

Ramgopal Varma is itching to tell a new story in his movies. You may garland him for his efforts or loathe him if you feel letdown, but you need to hand it to him for picking up stories that defy stereotype.

This time, in RANN, the maverick film-maker does an expose on the games the heavyweights in the media play to further their interests. RGV goes into the newsrooms and also behind it and throws light on the politician-industrialist-media nexus. Also, it's an insider's account of how news channels that are greedy for ratings sensationalize stories to grab eyeballs.

On surface, you don't want to know what goes behind the scenes and how, at times, news are 'created' by vested interests. But RANN scratches the surface and opens a can of worms. RANN also mirrors the fact that just like there are good and bad people in every field, there're some rotten ones in the media too who succumb to temptations and create news to climb the ladder of success.

RANN is a serious film and RGV knows what he's talking this time. It wouldn't be erroneous to state that you recall RGV's SARKAR while watching RANN, even though the two films are as diverse as chalk and cheese. You recall SARKAR because RANN is an equally powerful film that shows a world we've only seen from the exterior.


RANN is for those who enjoy serious cinema. It's more for the intelligentsia, for the thinking viewer. Definitely not for those who seek refuge in frivolous masala capers.


Vijay Harshvardhan Malik [Amitabh Bachchan] is the founder of a private news channel, India 24/7. A hardcore upholder of journalistic ethics, his channel is battling for survival. Jay [Sudeep], his son, looks at his father's news channel purely as a business enterprise that must make profits to justify its existence. He hates that his competition [Mohnish Bahl] is doing better than him.


The story takes a turn when a corrupt politician, Mohan Pandey [Paresh Rawal], decides to use the channel to his advantage by using Vijay's son-in-law Navin [Rajat Kapoor]. Pandey aspires to be the Prime Minister and indulges in a vicious campaign against his political opponent.


Navin is the most insecure man on earth and won't rest till he becomes the number one industrialist in the country. He, in turn, involves his brother-in-law Jay in Pandey's game plan.


A film like RANN would fall into the pit if [i] its writing wouldn't be razor-sharp and [ii] the choice of actors would be incompetent. RGV's movies, generally, are embellished with competent actors who deliver super performances. In this film, every member of the cast shines in his/her role, the length of the role notwithstanding.


The writing is watertight and convincing. Besides, the subject matter has been presented in the most simplistic manner, which makes it easy to decipher. However, the episode showing Riteish's investigation tends to get confusing at one point, but the climax compensates for the minor hiccups here and there.


Amit Roy's cinematography is eye-catching. Dialogues are power-packed. In fact, one can identify with the well-penned dialogues. The background score plays a crucial role. It heightens the impact of various scenes.


Amitabh Bachchan is spectacular yet again, especially towards the finale. His speech and the way he delivers it are remarkable. Sudeep is terrific. To stand up to giants like Bachchan and Paresh Rawal is no mean achievement. Riteish is only getting better and better with every film. In fact, he surprises you constantly.


Paresh Rawal, seen in an RGV film after a long, long time, is at his vicious best. Rajat Kapoor is incredible. Mohnish Bahl gets the role of a lifetime and he sinks his teeth into it. This film should open new vistas for him. Gul Panag is natural and so easy on the eyes. Neetu Chandra does her part well. Suchitra Krishnamoorthy is too good. Rajpal Yadav contributes to some funny moments. Neena Kulkarni and Simone Singh are perfect for their parts.


On the whole, RANN is truly a well-made film. No two opinions on that. The film should be patronised by viewers of serious, sensible cinema. Recommended!

Shirya item song in PULI

Shriya looks hot and sexier than ever. Her recent stills reveal that she sizzles more now than before. That is why director S J Surya has roped her in to play a special song in his current film, Puli starring Pawan Kalyan in the lead role. Shriya who already did item songs in films like Munna, Devadas, Tulasi, is appearing in special song for fourth time in Telugu. Interestingly, she also acted with Pawan in Balu as romantic interest and now doing an item song with him.
