"The Telikin Touch was initially designed to be a "senior friendly" PC with a touch interface so users wouldn"t need to use the keyboard and mouse. However…"

"… Traditional PC vendors often make claims that a certain application or function is "easy enough for grandma," but Chalfont, Penn.-based Telikin seems to offer a more ground-up approach to broad usability with its 20-inch Elite and 18-inch Touch touch-screen all-in-ones. Forgoing Windows, these systems use a custom operating system designed to provide intuitive access to basic computing functions like Web browsing, video chats, and other typical light-duty media consumption and communication-oriented tasks."

I have wanted a personal computer for a long time, but I did NOT want the complicated problems that can go with it. I am a senior and so I was cautious about this. I decided to get a 20" touch screen Telikin because this computer seemed to be less complex & easier for a senior to deal with. It was a very good decision. I got my computer & printer copier in Aug. 2011. I now exchange E mails with friends & family, do on-line searches, and one of my favorite things to do is to watch videos of my favorite artists. I really love the fact that Telikin can send me a blog from time to time with new information & it rolls right off the printer so I can look at the copy whenever I choose. Also when used as a copy machine I often do copies in color which I enjoy. Also Telikin has a very nice staff of people who can help if there are any questions.

"I was looking for a total solution...it really had to be intuitive...easy to learn...easy to use...and you would use it every day...and at a good price point, that"s how we chose Telikin."

"…it"s almost like a friend... I think Skype is wonderful...it"s very clear... you feel like you could touch the person [you are video chatting with]"

"The Telikin has had a major impact on my life. Using a computer is so much easier now with the touch screen, as I have limited use of my hand. I am on my computer every day video chatting with family and friends, watching movies, surfing the web, and sharing photos. The Telikin has helped me to stay connected and I can’t imagine not having it. I was introduced to The Telikin when our rehabilitation department at United Hebrew of New Rochelle invited me to be part of a research project with the Telikin company. I loved it so much, I called a relative and he bought me one and donated two to United Hebrew. They are in the library and now other residents can enjoy them too. Thanks Telikin, for creating a computer that brings the people I care about just a touchscreen away."

"As I am a 100 year old woman, what a blessing it is for me to have purchased the Telikin Computer. I am homebound and to have access to the outside world is indeed a miracle. The Technicians from Telikin, each and every one, have supported me in such an easy way to understand the Telikin. As I have low vision, I was helped considerably and the reading of my email, websites, and etc. I am eternally grateful to all the wonderful staff for helping me beyond my expectations."

"Excellent computer for seniors. I am a Linux system administrator, and I got this for my mother. She seems very happy with it. She has issues with short-term memory and is not technically inclined. I love the tech buddy feature! It works very well. The only thing that doesn"t work well is video chat. Spent a lot of time with customer service folks, who were very professional, but due to the recent merger of Skype and Microsoft, the Telikin video chat interface won"t work as advertised. Telikin says they are working on the problem and will install an update sometime in the future. Other than that, I am very happy with this computer, and so is my mother."

"My husband has never been interested in operating a computer. He is dyslexic and had difficulty understanding the idiosyncrasies of each computer. This computer is very easy to operate especially for a beginner."

system is resistant to viruses, so you will save money by not needing to purchase any of that. It also comes with a built in word processing component, so

you won"t need to purchase additional word processing software. The only thing we were not expecting is that, at this point, the printer must be hooked up

to the Telikin computer using a USB cable. I bought an HP wireless printer, but this computer can"t connect wirelessly to the printer. The computer DOES

connect wirelessly to the internet though. My mother loves this computer with the large print touch screen (comes with a touch stylus to avoid fingerprints)

"My mother was given a regular computer a while back and was utterly frustrated by it. At age 80 she couldnt even master email on it. She was lost. I was a little skeptical about the Telikin after reading one of the reviews. However, at Christmas, the family gave her one as a gift. I was amazed at how much more quickly she picked this up. Now she emails me regularly, Is able to save photos, listens to Pandora effortlessly, bookmarks favorites, plays bridge online, and surfs the web. It is a lot more intuitive than a regular computer. I even enjoy using it when I come to visit her. She is very set in her ways though. I was just trying to teach her to use the middle scroll dial on the mouse and she insisted that the best way to scroll was by dragging the scrollbar on the right of her moniter with her mouse. LOL. Mother knows best. I highly recommend it for the elderly."

"At last a computer that is easy for me to use. a keyboard that is easy to read. I am 86 years of age and this is the third computer I have had, and by far the best. It also helps me not having the third party installations.I was getting awfully tired of all those unwanted ads.

In this Arduino touch screen tutorial we will learn how to use TFT LCD Touch Screen with Arduino. You can watch the following video or read the written tutorial below.

For this tutorial I composed three examples. The first example is distance measurement using ultrasonic sensor. The output from the sensor, or the distance is printed on the screen and using the touch screen we can select the units, either centimeters or inches.

The next example is controlling an RGB LED using these three RGB sliders. For example if we start to slide the blue slider, the LED will light up in blue and increase the light as we would go to the maximum value. So the sliders can move from 0 to 255 and with their combination we can set any color to the RGB LED,  but just keep in mind that the LED cannot represent the colors that much accurate.

The third example is a game. Actually it’s a replica of the popular Flappy Bird game for smartphones. We can play the game using the push button or even using the touch screen itself.

As an example I am using a 3.2” TFT Touch Screen in a combination with a TFT LCD Arduino Mega Shield. We need a shield because the TFT Touch screen works at 3.3V and the Arduino Mega outputs are 5 V. For the first example I have the HC-SR04 ultrasonic sensor, then for the second example an RGB LED with three resistors and a push button for the game example. Also I had to make a custom made pin header like this, by soldering pin headers and bend on of them so I could insert them in between the Arduino Board and the TFT Shield.

Here’s the circuit schematic. We will use the GND pin, the digital pins from 8 to 13, as well as the pin number 14. As the 5V pins are already used by the TFT Screen I will use the pin number 13 as VCC, by setting it right away high in the setup section of code.

I will use the UTFT and URTouch libraries made by Henning Karlsen. Here I would like to say thanks to him for the incredible work he has done. The libraries enable really easy use of the TFT Screens, and they work with many different TFT screens sizes, shields and controllers. You can download these libraries from his website, RinkyDinkElectronics.com and also find a lot of demo examples and detailed documentation of how to use them.

After we include the libraries we need to create UTFT and URTouch objects. The parameters of these objects depends on the model of the TFT Screen and Shield and these details can be also found in the documentation of the libraries.

Next we need to define the fonts that are coming with the libraries and also define some variables needed for the program. In the setup section we need to initiate the screen and the touch, define the pin modes for the connected sensor, the led and the button, and initially call the drawHomeSreen() custom function, which will draw the home screen of the program.

So now I will explain how we can make the home screen of the program. With the setBackColor() function we need to set the background color of the text, black one in our case. Then we need to set the color to white, set the big font and using the print() function, we will print the string “Arduino TFT Tutorial” at the center of the screen and 10 pixels  down the Y – Axis of the screen. Next we will set the color to red and draw the red line below the text. After that we need to set the color back to white, and print the two other strings, “by HowToMechatronics.com” using the small font and “Select Example” using the big font.

Next is the distance sensor button. First we need to set the color and then using the fillRoundRect() function we will draw the rounded rectangle. Then we will set the color back to white and using the drawRoundRect() function we will draw another rounded rectangle on top of the previous one, but this one will be without a fill so the overall appearance of the button looks like it has a frame. On top of the button we will print the text using the big font and the same background color as the fill of the button. The same procedure goes for the two other buttons.

Now we need to make the buttons functional so that when we press them they would send us to the appropriate example. In the setup section we set the character ‘0’ to the currentPage variable, which will indicate that we are at the home screen. So if that’s true, and if we press on the screen this if statement would become true and using these lines here we will get the X and Y coordinates where the screen has been pressed. If that’s the area that covers the first button we will call the drawDistanceSensor() custom function which will activate the distance sensor example. Also we will set the character ‘1’ to the variable currentPage which will indicate that we are at the first example. The drawFrame() custom function is used for highlighting the button when it’s pressed. The same procedure goes for the two other buttons.

drawDistanceSensor(); // It is called only once, because in the next iteration of the loop, this above if statement will be false so this funtion won"t be called. This function will draw the graphics of the first example.

getDistance(); // Gets distance from the sensor and this function is repeatedly called while we are at the first example in order to print the lasest results from the distance sensor

So the drawDistanceSensor() custom function needs to be called only once when the button is pressed in order to draw all the graphics of this example in similar way as we described for the home screen. However, the getDistance() custom function needs to be called repeatedly in order to print the latest results of the distance measured by the sensor.

Here’s that function which uses the ultrasonic sensor to calculate the distance and print the values with SevenSegNum font in green color, either in centimeters or inches. If you need more details how the ultrasonic sensor works you can check my particular tutorialfor that. Back in the loop section we can see what happens when we press the select unit buttons as well as the back button.

Ok next is the RGB LED Control example. If we press the second button, the drawLedControl() custom function will be called only once for drawing the graphic of that example and the setLedColor() custom function will be repeatedly called. In this function we use the touch screen to set the values of the 3 sliders from 0 to 255. With the if statements we confine the area of each slider and get the X value of the slider. So the values of the X coordinate of each slider are from 38 to 310 pixels and we need to map these values into values from 0 to 255 which will be used as a PWM signal for lighting up the LED. If you need more details how the RGB LED works you can check my particular tutorialfor that. The rest of the code in this custom function is for drawing the sliders. Back in the loop section we only have the back button which also turns off the LED when pressed.

In order the code to work and compile you will have to include an addition “.c” file in the same directory with the Arduino sketch. This file is for the third game example and it’s a bitmap of the bird. For more details how this part of the code work  you can check my particular tutorial. Here you can download that file:

drawDistanceSensor(); // It is called only once, because in the next iteration of the loop, this above if statement will be false so this funtion won"t be called. This function will draw the graphics of the first example.

getDistance(); // Gets distance from the sensor and this function is repeatedly called while we are at the first example in order to print the lasest results from the distance sensor

You interact with a touch screen monitor constantly throughout your daily life. You will see them in cell phones, ATM’s, kiosks, ticket vending machines, manufacturing plants and more. All of these use touch panels to enable the user to interact with a computer or device without the use of a keyboard or mouse. But did you know there are several uniquely different types of Touch Screens? The five most common types of touch screen are: 5-Wire Resistive, Surface Capacitive touch, Projected Capacitive (P-Cap), SAW (Surface Acoustic Wave), and IR (Infrared).

We are often asked “How does a touch screen monitor work?” A touch screen basically replaces the functionality of a keyboard and mouse. Below is a basic description of 5 types of touch screen monitor technology.

5-Wire Resistive Touch is the most widely touch technology in use today. A resistive touch screen monitor is composed of a glass panel and a film screen, each covered with a thin metallic layer, separated by a narrow gap. For instance, when a user touches the screen, the two metallic layers make contact, resulting in electrical flow. The point of contact is detected by this change in voltage.

Surface Capacitive touch screen is the second most popular type of touch screens on the market. In a surface capacitive touch screen monitor, a transparent electrode layer is placed on top of a glass panel. This is then covered by a protective cover. When an exposed finger touches the monitor screen, it reacts to the static electrical capacity of the human body. Consequently, some of the electrical charge transfers from the screen to the user. This decrease in capacitance is detected by sensors located at the four corners of the screen, allowing the controller to determine the touch point. Surface capacitive touch screens can only be activated by the touch of human skin or a stylus holding an electrical charge.

Projected Capacitive (P-Cap) is similar to Surface Capacitive, but it offers two primary advantages. First, in addition to a bare finger, it can also be activated with surgical gloves or thin cotton gloves. Secondly, P-Cap enables multi-touch activation (simultaneous input from two or more fingers). A projected capacitive touch screen is composed of a sheet of glass with embedded transparent electrode films and an IC chip. This creates a three dimensional electrostatic field. Therefore, when a finger comes into contact with the screen, the ratios of the electrical currents change and the computer is able to detect the touch points. All our P-Cap touch screens feature a Zero-Bezel enclosure.

SAW (Surface Acoustic Wave) touch screen monitors utilize a series of piezoelectric transducers and receivers. These are positioned along the sides of the monitor’s glass plate to create an invisible grid of ultrasonic waves on the surface. When the panel is touched, a portion of the wave is absorbed. This allows the receiving transducer to locate the touch point and send this data to the computer. SAW monitors can be activated by a finger, gloved hand, or soft-tip stylus. SAW monitors offer easy use and high visibility.

IR (Infrared) type touch screen monitors do not overlay the display with an additional screen or screen sandwich. Instead, infrared monitors use IR emitters and receivers to create an invisible grid of light beams across the screen. This ensures the best possible image quality. When an object interrupts the invisible infrared light beam, the sensors are able to locate the touch point. The X and Y coordinates are then sent to the controller.
