Our capacitive multi-touch trackpad - SNOWPAD - is under revision for final production. Today, we've got new PCBs. We will come back to you soon with more beautiful products.
We are currently experimenting with different force matrix sensor arrays to improve the performance and usability of Snowboard. Here are our demo videos. Enjoy!
In this post, we would like to introduce Snowpad. We believe that this is a cool tool for your Arduino or microcontroller project.
What makes it different from other multi-touch trackpad is that it can be easily programmed by being connected to Arduino and microcontrollers.
It comes with capacitive multi-touch technology which are now popular in smartphones and tables and can detect up to 10 independent finger touches simultaneously. Of course, you can get all touch information such as xy information.
In the upper part of Snowpad, sockets compatible with Arduino Micro is places. You can just plug Arduino Micro into the socket and start your project.
Programming is done in Arduino IDE. Arduino is known to be a super-easy and flexible development platform. So, building your own multi-touch interface is a cup of cake.
Example codes and libraries written for Arduino will be provided. For example, a dozens of lines of code is enough to turn Snowpad into a real working multi-touch trackpad.
For a maker who wants to use other microcontroller, Snowpad is equiped with an external I2C interface. You can use your device you already have.
In this post, we want to show you our pressure mapping demo video which was briefly introduced in a previous post. In fact, pressure mapping (a.k.a pressure distribution measurement) needs a very expensive equipment. Thousands of dollars is just for a cheapest one.
Unlike other pressure mapping systems, Snowboard's pressure mapping function is implemented on a single chip. In addition, Snowboard embeds Arduino Leonardo so that a user can easily build his/her own custom pressure mapping system.
Price? We're still under process of finalizing manufacturing but we will disclose it soon and you will be very surprised - because it is too low!!
So stay tuned and enjoy our demo video!!!
Our touch development platform called Snowboard was assembled a few days ago and has been tested. We are very happy to let you know that all major features are functional properly.
Snowboard is designed to be a very versatile and affordable touch/tactile development platform. It has three primary features - pressure distribution measurement, analgog capacitive switch, and capacitive multi-touch.
In this post, we will briefly introduce photos of capacitive multi-touch and pressure distribution measurement of Snowboard.
Together with our Snowpad - a capacitive multi-touch track pad of our own, Snowboard is instantly turned into a capacitive multi-touch developmetn platform as shown above.
Besides capacitive multi-touch, it also supports a resistive matrix sensor. Traditionally, this kind of sensor has been popular to build a pressure distribution measurement system. In these days, its application is being widen to include general multi-touch devices. Unlike capacitive multi-touch, an input device made of this kind of sensor can detect force/pressure which means that the device can provide more rich interaction. Snowboard supports 10x7 and 10x16 sensors and is able to gather raw pressure data from any resistive matrix sensor.
