How can I use the stylus and touchscreen on my ConceptD Ezel CC314-72G?
Q: Which pen input technology is used on the ConceptD 3 Ezel?
A: Wacom AES technology with Acer Active Stylus.
Q: Which third-party pens are compatible with the ConceptD 3 Ezel?
A: The WACOM Bamboo Ink and Bamboo Ink Plus both support AES technology. Make sure you switch the protocol and change the tip to AES.
Q: Why am I experiencing jitter and distorted lines while drawing on the ConceptD 3 Ezel touchscreen?
Some Acer products use Active Electrostatic (AES) technology that uses a sensor grid in the LCD panel, and conductive tip in the stylus, to determine the physical touch point. The system reports the location of the stylus based on the closest grid intersection many times each second. Drawing too slowly may cause lines to appear wavy because more locations will be reported. This is inherent to all products that use AES technology, and not exclusive to Acer products. We are currently working with stylus manufacturers to help optimize stylus performance on our products.
Q: How can I fix jitter/distorted lines when drawing on the ConceptD 3 Ezel?
A: The best way to reduce line jitter is to increase the speed of your strokes. If your lines are not as straight as you would like them to be, we recommend trying the following suggestions: The images below illustrate the difference in the way slow and fast strokes will be reported. The diagonal lines in the images show the lines drawn with the stylus, and each change in color between red and blue shows when a reporting point (green circle) is plotted.
If your lines are not as straight as you would like them to be, we recommend trying the following suggestions:
- Draw your lines with quick, fluid strokes.
- Turn on line smoothing / brushstroke smoothing (settings such as “Line Stabilizer” or “Stabilization”) in the application you are using (examples include Photoshop, illustrator, CLIP STUDIO) to get smooth inking results.
Q: Is there firmware patch available to address this jitter issue?
A: A firmware update will be posted on the Acer support website soon. Estimated availability is November 2020.
Q: What are the limitations of Wacom’s AES technology? How is it different than Wacom’s EMR technology?
A: Active Electrostatic (AES) and Electromagnetic Resonance (EMR) are two main digitizer technologies. Devices with AES pen are also good for artists and designers, though require some getting used to and compensation.
How AES works:
Wacom’s Active ES is an electrostatic capacitive pen coupling technology. It consists of a display containing a sensor with multiple electrostatic grids arranged at right angles to one another that interacts with a Wacom digital pen. One sensor grid and the pen act as the transmitting unit that generates an electrical field; the other grids act as receiving units. The pen's position is identified based on differences in the charge amount detected on each sensor grid receiving unit.
How EMR works:
Wacom’s patented electromagnetic resonance (EMR) technology consists of a layer of sensors that sits behind the device’s Liquid Crystal Display (LCD) screen and a layer of hardened glass. The sensors are arranged in an alternating vertical/horizontal grid pattern. Each sensor is precisely calibrated and emits a weak electromagnetic signal. Together, these signals create a magnetic field that extends about 5mm beyond the glass surface of the device.
Q: Does palm rejection technology work on this device?
A: Yes, the palm rejection allows you to rest your hand naturally on the screen while drawing or sketching without making unwanted marks.
Q: Does the pen/stylus require charging?
A: The pen does require charging and will quickly charge when inserted into the storage bay on the computer.
Q: How long is the battery life for the pen? Is there a sign for low battery?
A: Charging for 15 seconds allows for approximately 90 minutes of use. Charging for 300 seconds will allow for more than 100 minutes of use.
Q: Can I assign different functions to the buttons on the pen?
A: The upper button acts as the right click on your mouse and the lower button acts as an eraser. These functions cannot be altered or programmed.
Q: Can I use the pen on other devices or tablets?
A: Acer Active Stylus should be compatible with any devices using AES protocol, however Acer can not guarantee compatibility on third party products.
