Can a smartphone be a HomeLab ?
Résumé
There are 2 billions of smartphones on earth. Each has more than 10 sensors, which collect data to localize the smartphone in space and time, to follow its displacement and to analyse gestures and movements. Through a real-‐time scientific treatment, the smartphone human interface makes available to everybody this monitoring of the world around us. This interface based on a global approach of the connected man is due to design. Interfaces based on new collaborations between sciences and design, have been developed for smartphone health applications. In field of education, we have entered building a new smartphone human interface dedicated to investigation of gesture and movement at K-‐12 level. This new program follows the one based on a software iMecaProf now used to teach physics at university. In real-‐time and interactively, it analyses localisation and displacement and represents results on a PC screen within science formalism. For associated students in design, innovation and challenge is: " what real-‐time and interactive representation of smartphone data, so that K-‐12 students can discover gesture and movement using gyro and accelerometer data? " Accelerometer records a trace associated to trajectory but also to the dynamic of displacement, closely related to rhythm in music and dance.
