„murphie“ is the first idea to use sensors as a physical connection between body and a operating system or tool. it works like an extension of your arm and is usable in lots of variations, while at the same time, due to its minimalistic and subtle appearance, you won’t really feel that its there.

it works with two devices. the muscle sensor(„armurphie“) and the operating machine(„operphie“) with exchangeable tools. through a muscle reflex sensor on the arm, you can manually control various ordinary household devices and do household chores. The target demographic will be handicapped individuals who lost one of their hands but it is also great use for individuals without disabilities.

the sensor and operating system communicate wirelessly via bluetooth and wifi. no matter where the user is – he or she is able to control the operating systems or smart home devices in the same room without touching them. simple hand gestures like pointing or twisting make it easy and intuitive. with a „telepathic touch“ the user will have more joy doing daily house chores and is more independent as a handicapped individual.
user journey

the project was realized in cooperation with sony at the university of the arts in kyoto.

armurphie and operphie below

here seen the example operation of opening a jar using the tool remotely controlled by „murphie“.

for the working prototype there have been used two Arduino nano ble 33, a myoware muscle sensor and battery a basic dc motor.

since it was the first time hands on this kind of components, it took a lot of research and time. eventually it was working by using the values that were given by the muscle sensor – to use to control the dc motor via bluetooth connection between „armurphie“ and „operphie“. the two devices for arm sensing and operation.

most of the hardware components for the prototype were 3Dprinted. strings and fabric were used to make the „armurphie“ manually adjustable.
