A.R.C
A.R.C. stands for Analog Reflection Calibrator. It is a simple pair of glasses… with rotatable polarizers.
A single EM wave ray has some polarization, which is, in a way, the direction the electric and magnetic fields oscillate. A polarizer restricts light, depending on the direction of oscillation. When we get to a single ray, if the polarizer’s angle does not exactly match the directions of oscillation, then things get a bit probabilistic (quantum-y)
A very interesting phenomenon with oscillation is that when the angle of the light to a surface on which it reflects is 45 degrees. This is when the light gets polarized parallel to the surface. This angle is known as Brewster’s angle.
A.R.C. uses this, and features rotatable polarized lenses, which can be turned by the user, to either amplify or diminish the reflection on a surface (this doesn’t work on a mirror, though). This makes it useful in most cases (where the angle is close to 45 degrees), when you want to look at a shiny surface, or a reflection in more detail.
UltraVision
UltraVision… the tool that makes you focus… literally. Even if you move your VR headset, look around, it always looks at the same object, or part of the object. That makes it handy for when you need to measure something accurately, or when you are soldering. With a simple camera zoom, all motion and vibration gets amplified, making it unusable. This prevents that from happening, and comes with an AR ruler which is to scale, in case you need it.
It uses an app running on a VR headset, which analyses its surroundings in 3D with depth perception, recognising planes and surfaces. Tapping on a surface sets an invisible physical object there. Every frame, the processor identifies the angle of the anchor, and it’s position on the screen. From this, the user is displayed with a localised video feed. Tapping on the image also zooms in at various levels. Tapping on the right side also adds an object where it has been tapped - but this time a ruler. Turning your device can change the angle at which the ruler is dropped.
Hologram Generator
Have you ever seen a hologram in a movie? This device can make the same thing appear in front of you.
​
It involves a reflective, yet transparent glass bowl, in which there can be placed a real object, or a display showing an image. The light reflecting off of it, or coming from it is reflected and converges around 10 cm above the surface of the glass bowl, and appears to stay in the same position from all angles, creating the illusion that it is in that position. However, as it is just light, you can pass your finger through it.
​
If the display is 2D, the hologram is also 2D. However, when you place a real life object, in 3D, you can also see it from all angles with the hologram generator.
​
There is another version of the same thing, using a lens instead. While the "floating height" is greater, the image can only be viewed in a limited range of angles.
3Draw
Presenting… 3Draw! This is a tool that transforms your regular 2D drawing experience, and brings it to the 3rd dimension. You can pinch your fingers together to doodle, sketch or annotate what you see around you, with AR. And it’s 360°. It’s not just great for drawing. You can pull images off of screens into your workspace, and even enlarge them. Pinch your right thumb and index finger together to start drawing, just like how you would grasp a pen, and release when you’re done, or when you want to move it. Do the same on your left hand to take a screenshot of that region, move it around, and release when you’ve decided. Tap it again with your left hand to enlarge it. Lastly, you can add background images or colors (if you don’t want any background distractions), and you can customise the colors you use. When you’re done, just wipe your right hand, and erase the board
It uses an app that runs on your phone, put inside a VR headset (with a hole made for the camersa), tracks your finger through VISION (which makes it iOS compatible), and draws along with it. It calculates the distance between your fingertips, and if it’s low enough, it starts to draw. It uses the phone’s gyroscope and accelerometer to track physical rotations, and re-orient the doodles and images. It takes a screenshot when you click with your left hand, and moves it around as well.
