Work that is too early to have a page of its own.
The eventual form is a patch worn on the neck that senses the carotid pulse directly — a signal that is difficult to read reliably by hand and difficult to read at all from the wrist.
It is an alternative route to heart rate: rather than reading light through the skin, a pressure sensor picks up the physical deformation the artery makes as it expands, and that deformation is translated into a pulse rate.
It is at proof-of-concept stage with a patent pending, so there is not much to show yet. I'm a co-inventor. More will go here once it is further along.
HexR Haptic Glove
A haptic glove for VR and AR that lets you feel the virtual world.
Chief Technology Officer (2025)
The problem
VR is moving fast and hand tracking is becoming seamless across every major headset. As the industry drops controllers, touch is the next leap.
HexR is built for that future: a glove that adds tactile feedback to training and simulation, where being able to feel what you are doing is the difference between watching a procedure and learning it.
My part in it
As CTO I lead the glove's whole software ecosystem — the plugin architecture, the developer-facing UI, and the interactive demos that show what the hardware can do. I lead integration across Meta Quest, Pico, HoloLens, Python and ROS so the glove works wherever our customers already are.
Beyond software I was directly involved in R&D and prototyping of our proprietary haptic actuators, and I still oversee small-batch manufacturing ahead of full outsourcing. I manage commissioned VR simulation projects — including medical simulations with NUH — run client presentations, support sales, and produce the manuals and instructional assets partners rely on.
Threads
Demo experiences built to prove out what haptic feedback changes in VR.
The plugin, docs and tutorials developers use to build for the glove.
Commissioned simulation work, including medical simulations with NUH.
Manuals, instructional guides and client-facing material.
ARIS
A strength-sensing wearable, now in its second generation. One built to log your own training; one built into an ecosystem.

For people already training. Counts and identifies reps so power and progressive overload are tracked instead of remembered.
For clinicians and physios. The FlexR band measures muscle expansion at home, so adherence and effort come back as data instead of patient recall.
aris.microtube.tech →ARIS — the original
2022 → · shipped to both app storesThe problem
This one started with my own problem at the gym: there was no tracker that could actually count a rep.
Health tech had gone personal everywhere except the weights room. Serious lifters care about power output and progressive overload, and were keeping both in their heads or in a notebook. ARIS was built to be the pocket gym diary that fills itself in while you train.
My part in it
I'm co-inventor of ARIS at Microtube Technologies. Building on Microtube's patented stretchable sensor, we developed the hardware and the mobile application together — sensing, the rep-identification algorithm, the app, and the design around all of it.
Within two years we launched on the Google Play Store and the iOS App Store.
The app
The band reads the movement; the app turns it into a log you never had to write.

ARIS Co — the next generation
Prescribed is not the same as performed.
A different problem
The home programme is where rehab is won or lost, and it is the part the clinician never sees. What comes back is patient recall.
So the second generation is a patient-management tool, not a better tracker. The FlexR band measures muscle expansion on the limb being rehabilitated, and every home session comes back as adherence, load and effort.
What changed
Explore the product
Android build in testing — iOS in progressMuscle expansion read at the limb, not motion inferred at the wrist.
The app runs the prescribed session — exercise, sets, rest, video.
Fourteen days of work shaded onto the body, so gaps are obvious.
Adherence and effort per client, visible before the next appointment.
A session history that exports as a PDF for documentation.
The Android build runs in demo mode without a band, so you can walk the whole flow. Console accounts are opened by invitation.
Darurice
A card game with cute characters, strategic gameplay, and karma.
Where it came from
A painting I made for my room: a Daruma riding a sushi horse, leading his rice army to war. The game grew out of that.
Why I built it
Darurice is the passion project I worked on in my free time at university. I wanted a way to practise digital illustration and character design, and a card game was the perfect excuse to merge drawing with gaming.
Since I knew I wanted a cast of cute characters, I built the theme around rice — and the Riceniverse followed.
