By clicking the “start” button (b) the application runs and several tabs can be selected (c). The “Procedure” box (d) provide to the user the instructions to perform the assay, then the Begin button allow to proceed to the “Checklist” box (e) where preset timers guide the user through the correct incubation times before BL image acquisition. The instructions can be also eluded by selecting “Test sample” in the home page, which jumps the user directly to the checklist. At the end of the countdown the smartphone camera is activated and the user can simply touch the “Acquire” button to capture the BL image of both the test and control wells. (f) The acquired images are rapidly analyzed on the smartphone and the sample toxicity result is displayed as “Cell viability” value and a warning message (Safe, Harmful, Highly toxic). BL image and results can be also saved for downstream application (i.e. sending results to a central laboratory). --- # How does printing enhance a mobile phone? .left-column50[ [Phone for potentiostatic control](https://ieeexplore.ieee.org/abstract/document/6916991)  ] .right-column50[ New ways of interacting Phone as embedded computer New ways of sensing - exploits ability to play sounds - serves basic functions of a potentiostat in controlling an applied potential to oxidise ECL-active molecules - resultant photonic signal is monitored using the camera in video mode. - combined with paper microfluidic sensors ] ??? The audio jack supplies the potential to the paper microfluidic sensor, while the resultant emission is detected by the camera in video mode. Both the excitation and detection processes are controlled by a software application which can also transmit the results via e-mail. The black plastic sleeve surrounding the top of the phone holds the sensor adjacent to the camera and blocks ambient light. --- # How does printing enhance a mobile phone? .left-column50[ Printed Analytics ![:youtube Printed objects whose use can be sensed, W1V2AgDbgTQ] ] .right-column-half[ New ways of interacting Phone as embedded computer New ways of sensing - uses backscatter technology - works in range of a modified wireless router ] --- # Summary: What does physical computing offer us? .left-column-half[ New ways to interact - capacitive sensing facilitate by conductive plastic/thread - microphone + machine learning New ways to sense information - fluid properties - audio - backscatter ] .right-column-half[ New ways to combine devices (e.g. through bluetooth sensing of physical hardware) Benefits: - modify a device beyond what the manufacturer expected - apid prototyping of novel solutions ] -- # END OF DECK --- # Moon House Video ![:youtube Video of a robot 3d printing a round house, 8zt_3Gs1ksg] --- # Accessible Game Control ![:youtube Xbox adaptive controller intro, 9fcK19CAjWM]
