We are on Crowdfunding Spotlight of Berkeley Souring Group
is a device to bring the screen of smart phones/tablets onto any surface, and
turn the surface as a touch input at the same time. The surface can be flat,
non-flat, or even a piece of glass! With HaloTouch, we unleash the true power
of touch input and create a more natural way to interact with your smart devices
with an affordable price!
WiFi Display is supported
by Android (with version 4.2 or higher). The 2-way communication feature is
called User Input Back Channel (UIBC) in Miracast, and is supported by Android.
Unfortunately, it’s not fully implemented so we designed our way to make this
feature available. The solution will be published as an open source library so
any manufacturer can include this library and enable the remote input feature
in the future!
Currently we are reconstructing
our library to make it more flexible and extendable. In addition, some modifications
are required to avoid violating NDA (Non-Disclosure Agreement) agreements that we
signed chip vendors. The information will be updated on our Kickstarter project
HaloTouch, you can turn any wall/surface into a big touch screen of your smart devices,
such as Android phones and tablets. With the remote & larger touch screen,
users can download a drawing application to form an interactive whiteboard.
However, the user scenario is not limited to business or education purpose. HaloTouch
is all about information sharing, so you can show a map, browse the Internet,
or even play games with friends. Here are some using occasions:
Educating or business
any drawing application as an interact whiteboard. It’s easy, free, and all the
images can be saved on your smart phone to make sharing a single click away.
Sharing photos or other information: With a larger screen,
showing photos from last trip or browsing Google map friends could be much easy
and more interactive.
Playing games with friends: With HaloTouch, games
become even more interesting. Turing a regular wall into a 50” (or even bigger)
touch screen makes it possible to control games by you and your friends at the
those all? Of course not, HaloTouch’s true potential is only limited by your
imagination. By projecting on non-flat or transparent surfaces, HaloTouch
creates a “sci-fi” way to interact with smart devices; and remember, it only
costs few hundred bucks!
On non-flat surfaces: Since one of its underlying
technologies is motion detection, HaloTouch can be applied on non-flat
surfaces, including statues, waterfalls, or even on smog! For example, teachers
can project the inner structure of a vehicle on a real car, and touch the
vehicle to see how an engine consumes gasoline to provide the energy for
On a glass: Yes! It’s reproducing Tom
Cruise’s famous scene in the Minority Report movie. For now on, you can do this
at home without costing a fortune!
After connection, our app
will transmit the screen of your smart phone/pad to HaloTouch, and bring the
screen to the projector by HDMI cable.
At the same time, the
camera on HaloTouch will capture the position of TouchRing, and translate the
position as a touch input on your smart phone.
WiFi Display: It’s also called Miracast
in Android’s world, which is the technology to capture the screen of an Android
device and transfer it wirelessly onto remote display (could be a monitor, a projector,
Motion Detection: The camera on HaloTouch
captures the position of our TouchRing and simulates it as the touch input on
the smart phone/pad. Since the position is captured by a camera, the TouchRing
can be used on flat or non-flat surfaces, as long as the TouchRing is visible
by our camera.
Although HaloTouch is rather a new concept for users, we spent quite a long time to come to this stage. Here are major milestones in our R&D process:
- Aug, 2012: We announced a totally software version of WiFi Display on Android, with the typical latency of one frame (0.06 second).
- Feb, 2013: With the Miracast standard announced by Google in late 2012, we switched our solution to Miracast, and started to integrate motion detection sensor onto our product.
- Jul, 2013: The first working prototype of HaloTouch.
- Nov, 2013: version 1 of HaloTouch hardware.
HaloTouch has following limitations:
privilege: Although Miracast supports 2-way communication, Android doesn’t
fully implement this future. Therefore, we design our version on this part, and
it needs root privilege to install our library. We will open our code so any
manufacturer could include the feature freely. In that case, you don’t need to
root your device in the future.
don’t want to lie to you. Any wireless remote screen technology has latency! In
usual environment, the latency is around 0.1~1.5 seconds, which is fair enough
for ninety percent of applications. The exception would be 3D gaming (e.g. Asphalt
8) and Full HD video playback. In both scenarios, WiFi Display is not the best
solution we recommend. However, our goal is to fulfill 90% of user scenarios
with an affordable price, which is indeed realized by HaloTouch, and we wish
you will enjoy it, just like us.
support: iPhone is not supported because Apple doesn’t support WiFi Display. iDevices
(iPhone/iPad/iPod) only support Apple’s proprietary AirPlay protocol, which is
Apple’s version of WiFi Display.
150K: 2 new colors for
HaloTouch & TouchRing
200K: A touch pen accessory
that can be attached onto TouchRing. A pen styled TouchRing will provide better
user experience in writing characters.
300K: 2 new TouchRings in different sizes
The best part of
Kickstarter is sharing and encouraging. There are always great ideas to take
action, but only few could be delivered by big companies. Start-ups like us
fill the technology gap and bring products from merely a concept to an operable
prototype, like our HaloTouch. It’s a new concept to communicate with smart
devices and, by sharing our progress, Kickstarters could decide the next stage
or even a better user scenario for this prototype. By successfully fund,
Kickstarters not only support us in monetary manner, you also confirm the
requirement is indeed there. Therefore, we are empowered and encouraged to
bring the concept to its final stage – production and bring it to market for
By pledging our project, you can expect:

You may find the expense
of software development is quite small. It’s not because this part is easy. On
the contrary, the project goal might be doubled if we added the programming
cost. The thing is we really want to see HaloTouch on the market and we are
willing to eat the marshmallow a bit later!
Halo-Digi Technology is
founded by a bunch of nerds, homebodies, daydreamers, and boring programmers. If
we do have something in common, it’s the passion to make something different as
our footprint in the world!
We’ve seen the possibility
of a whole new way to interact with smart phones two years ago, and decided to
try this new concept of separating computing and display. In short, users bring
a cubic as the motherboard in the future; the display is thin and connected to
the cubic wirelessly. Therefore, users can choose different display sizes for
different occasions. For example, 20” display as a PC, 10” display as a pad,
and 4” as a smart phone! The key technology in it is called WiFi Display, so we
built a totally software solution (our own version) of Miracast, which is
actually prior to Android’s announcement. Combined with motion detection
technology, we call it HaloTouch.

Risks and challenges
HaloTouch is a complete system with WiFi & sensor hardware and a fully Linux operating system, which means it can become quite complex both in developing and manufacturing phase. The complexity comes from following parts:
Product Hardware Design: Unless the stretch goal is achieved, we won’t change current design on our PCB and HaloTouch would stay the same dimension as on our video. The risk on hardware mainly comes from the design of TouchRing. We've tried ring, pen, and glove shape in our lab. The challenge is to design a comfortable yet precise feedback (to be clicked) device to be attached on users’ fingers. Therefore, we might change the shape of TouchRing to achieve the goal. Or we may just set up a poll to for users to choose! Any update or decision will be put on our blog and Kickstarter.
Manufacture: We chose one of the largest OEMs in PC industry, which should eliminate most of the manufacturing risk. However, there is always small possibility to cause issues in mass production. If that do happen, we will make sure the root cause be clearly explained to our backers and it should only impact the production date rather than product function.
Compatibility and Wireless issue: HaloTouch is a product combining WiFi and motion detecting sensor. The demo on our videos are all on our device, which means basic mirroring, touching, sweeping can be performed correctly. However, it doesn’t guarantee a flawless user experience. Wireless connection might face glitch due to WiFi stability and motion detection might be malfunctioned if the sensor faces strong light source. To eliminate the issue, we chose key components from 1st-tier suppliers to enhance product stability. Most importantly, many of these issues can be solved by correct installation, which will be further explained in FAQ section and our product blog.
