Studies have shown that smartphone-based solutions can indeed help to control the spread
of infectious diseases. However, as we discuss in this article, they cannot reliably
record all contacts. Furthermore, the classification of whether a contact is relevant is
based on contact duration and proximity, which can only be determined with limited
granularity using smartphones. On the other hand, dedicated contact-tracing devices were
questo non e' vero
dipende dall'algoritmica scelta
io ho seguito un progetto che con BTLE stimava la distanza con un errore di 50cm su 2m di
distanza. usato da centinaia di migliaia di persone in azienda in giro per il mondo.
usato per notificare di mantenere distanza se si scendeva sotto soglia.
dimostrato di avere un effetto edeucativo (la gente imparava a stare a
distanza).
ovviamente, non basato su google/apple.
not available immediately because they required the development and production of custom
hardware. Such custom-designed hardware in the form of wearable devices, along with
custom-built communication protocols for contact tracing, can potentially overcome many
limitations of smartphones. While such devices are being developed, they have not
attracted sufficient attention of public health policymakers, and very little discussion
about them has reached the public sphere. Moreover, many medical professionals and
policymakers are not adequately aware of the limitations of smartphones or the advantages
of dedicated wearable contact-tracing devices. The goal of this article is to highlight
this gap, especially considering that contact tracing will be an important requirement in
the future, even after we overcome this ongoing COVID-19 crisis.
