Welle transforms any surface into a smart touch-controller

So, let’s talk about smart devices. After all, that’s all we speak about nowadays anyways right? Lately we’ve seen smart outlets, smart locks, smart doorbells, and so much more. Instead of taking each individual item that already exists and turning it into a smart-version of itself, today we have a more practical idea to discuss.

Welle is a device that can turn any surface into a smart interface. It’s not quite the type of thing that will finally allow you to use any table as a keyboard (via projection). It’s more like an invisible knob, dial, lever, and trackpad, in which you can decide how to best configure each surface.

To understand a little bit more exactly what this device is, you can see its shape and size below. It’s a little rectangular box that gives you the ability to use simple gestures or shortcuts to control your favorite functions on various connected devices. It already works with some services and devices you may be familiar with like Nest, IFTTT, and even Microsoft PowerPoint.

The method of connection is via Bluetooth, with settings and features can be configured in an app for iOS and Android. Once you place your Welle on a surface, you can view the gestures you make in real-time on your smart device within the app. The Welle also has an open API for all the developers in the audience.


Refined Sonar technology is used to instantly turn any surface into a smart controller. You may recognize the term from your history textbooks, as this special system is often used in the military. Once the Welle notices your hand gestures, it’s extracted and then translated into the respective IoT device instruction.

Ultrasound stands out with meter-level detection range, compared to Infrared that includes only centimeter-level range. Additionally, low-light does not have an effect on detection performance.

Welle is around three inches long and weighs just 1 ounce, making it compact and portable. Simply put, the installation process involves connecting via Bluetooth, setup using the smartphone app, powering on Welle, and then assigning gestures. It includes 3 color LED indicator lights, and the battery can last up to 30 days on a single charge via Micro USB, depending on usage.

Welle can be pre-ordered on Kickstarter for $69, a $30 savings off the projected retail price. Expected delivery is this October.
