The allure of touchscreen technology has transcended beyond smartphones. Many individuals now desire the convenience of a touchscreen computer, allowing them to tap, swipe, and pinch directly on their computer screen. While many brands offer pre-built touchscreen computers, DIY enthusiasts might wonder: Can I make one myself? Absolutely! Here’s a comprehensive guide to crafting your very own touchscreen computer…and a method for getting it done (for you) quickly and for under $100.

The Easy Way

To Add Touchscreen functionality to an existing laptop there is a product out there called the AirBar by Neonode. This easy to use and affordable device lets you add touchscreen capabilities to your laptop. From the manufacturer:

AirBar gives your non-touch notebook touchscreen functionalities. The sleek, lightweight device emits an invisible light field over a laptop screen that senses your finger touch. AirBar will allow you to experience the best of Windows by simply attaching it to the bottom of your laptop bezel with the magnets provided, and plugging it into the USB port. You will be able to tap, pinch, zoom, sweep and rotate instantly. AirBar for Windows laptops will work out of the box not require any software or driver downloads. We call this “Plug-and-Touch”. With AirBar attached to your non-touch Windows laptop, you will be able to sweep through music, images and video files, scroll whilst web browsing, or highlight text and paragraphs in your Word, and PDF documents, or pinch, zoom, rotate in your maps, and photos. You can also simply select an app on your desktop or taskbar, a hyperlink or use it to intuitively access functions in Windows that you would not have otherwise, such as edge-swipes. AirBar will make using your existing laptop fun again, and increase your productivity. Many people instinctively touch their laptop screens to select something, but realize it’s not a touchscreen. Well now AirBar is your answer. AirBar is ONLY recommended to work with laptops running Windows, and ONLY for laptops sizes 13.3″, 14″ and 15.6″ so you must choose the RIGHT SIZE for your laptop. AirBar for Windows is NOT intended for monitors, or MacBook notebooks. Please read system requirements before making a purchase.
