We turned a MacBook into a touchscreen using only $1 of hardware and a littlebit of computer vision. The proof-of-concept, dubbed 'Project Sistine' afterour recreation of the famous painting in the Sistine Chapel, was prototypedby me, Kevin, Guillermo, and Logan in about 16 hours.
The basic principle behind Sistine is simple. Surfaces viewed from an angletend to look shiny, and you can tell if a finger is touching the surface bychecking if it's touching its own reflection.
Kevin, back in middle school, noticed this phenomenon and built ShinyTouch,utilizing an external webcam to build a touch input system requiring virtuallyno setup. We wanted to see if we could miniaturize the idea and make it workwithout an external webcam. Our idea was to retrofit a small mirror in front ofa MacBook's built-in webcam, so that the webcam would be looking down at thecomputer screen at a sharp angle. The camera would be able to see fingershovering over or touching the screen, and we'd be able to translate the videofeed into touch events using computer vision.
The jury still seems to be out on whether the new MacBook Pros with Touch Bar are a courageous leap forward or a desperate cry for help. But regardless of which side you're on, the price is. Use your favourite gestures and moves from the trackpad right on the screen. MacOS® operating system does not support touch like Windows 10 does, but with AirBar you can turn the screen into a big trackpad. With a quick software installation, you can use multi-touch gestures right on the screen of your Macbook Air 13.3. It was touch and go there for a while: The possibility of ever seeing a MacBook with touchscreen features seemed remote. But a new version of a computer accessory called the AirBar makes this a. If you ever wanted a touch-screen display on your MacBook Air then you might want to look into AirBar. AirBar Has Been Around for a While, But Now it Supports the 13-inch MacBook Air. The feature works on most trackpads built into relatively new MacBook Pro and Air models, including any with multitouch support. Turn On Tap To Click with Mac OS X Trackpad Preferences The best way for most users to enable touch tapping on their Mac is through System Preferences.
Our hardware setup was simple. All we needed was to position a mirror at theappropriate angle in front of the webcam. Here is our bill of materials:
- Small mirror
- Rigid paper plate
- Door hinge
- Hot glue
After some iteration, we settled on a design that could be assembled in minutesusing a knife and a hot glue gun.
Here's the finished product:
The first step in processing video frames is detecting the finger. Here's atypical example of what the webcam sees:
The finger detection algorithm needs to find the touch/hover point for furtherprocessing. Our current approach uses classical computer vision techniques. Theprocessing pipeline consists of the following steps:
- Filter for skin colors and binary threshold
- Find contours
- Find the two largest contours and ensure that the contours overlap in thehorizontal direction and the smaller one is above the larger one
- Identify the touch/hover point as the midpoint of the line connecting thetop of the bottom contour and the bottom of the top contour
- Distinguish between touch and hover based on the vertical distance betweenthe two contours
Shown above is the result of applying this process to a frame from the webcam.The finger and reflection (contours) are outlined in green, the bounding box isshown in red, and the touch point is shown in magenta.
The final step in processing the input is mapping the touch/hover point fromwebcam coordinates to on-screen coordinates. The two are related by ahomography. We compute the homography matrix through a calibration processwhere the user is prompted to touch specific points on the screen. After wecollect data matching webcam coordinates with on-screen coordinates, we canestimate the homography robustly using RANSAC. This gives us a projectionmatrix that maps webcam coordinates to on-screen coordinates.
The video above demonstrates the calibration process, where the user has tofollow a green dot around the screen. The video includes some debuginformation, overlaid on live video from the webcam. The touch point in webcamcoordinates is shown in magenta. After the calibration process is complete, theprojection matrix is visualized with red lines, and the software switches to amode where the estimated touch point is shown as a blue dot.
In the current prototype, we translate hover and touch into mouse events,making existing applications instantly touch-enabled.
If we were writing our own touch-enabled apps, we could directly make use oftouch data, including information such as hover height.
Project Sistine is a proof-of-concept that turns a laptop into a touchscreenusing only $1 of hardware, and for a prototype, it works pretty well! With somesimple modifications such as a higher resolution webcam (ours was 480p) and acurved mirror that allows the webcam to capture the entire screen, Sistinecould become a practical low-cost touchscreen system.
Our Sistine prototype is open source, released under the MIT License.
