halo

a more immersive take on music production knobs.


Fall 2015 
Personal Project




A MIDI controller is a device that provides physical input for virtual instruments. Without its virtual counterpart, it does not produce sound.

Typical controllers include keyboards, drumpads, knobs, sliders, and mixed-use devices. Over the years, these devices have been redesigned and reimagined for better playability, expression, and portability.

However, knobs have pretty much remained the same, yet they are quite essential to the music production process. I sought out a form factor that is more inviting to use, robust to carry, and evoke a more expressive physical interaction.
High Break Point
Protruding from the top surface of MIDI controllers, knobs often get snapped off during transport.
Poor I/O Ratio
Parameters typically span 127 levels of change, which can be hard to manage with small knobs.
Too Many / Not Enough
Different use cases require different amounts of control. Sometimes there are just too many.

Halo draws the user in by utilizing a concave surface and negative space of interaction, a key component that is not apparent in traditional knob controllers.





Rotate dial to adjust a parameter.



Swipe in the negative space to navigate to another parameter.

An IR sensor fires downward onto the surface Halo is resting on - this allows for simple left and right swipe gestures to navigate between set parameters.







NOTES
Through this project I was able to practice more advanced surfacing techniques in Rhino as well as basic animation with Keyshot and After Effects. Halo was also selected to be exhibited at the 2017 Global Grad Show in Dubai during Dubai Design Week.
