Sensorised Low-Cost Pencils for Developing Countries: A Quantitative Analysis of Handwriting Learning Progress in Children with/without Disabilities from a Sustainable Perspective

“…The total cost of assembling 50 units of the proposals by Junior et al [44] and Di Febbo et al [43] was 7560 USD and 9460 USD, which are roughly triple and quadruple of our STPP, respectively. Table 5 shows the investments needed to provide for the whole province: Table 5.…”

“…The total amount required to make the 50 pencils was 2500 USD. We compared this cost with what we would have spent in mimicking the features of the devices presented by Junior et al [44] and Di Febbo et al [43], chosen according to the following criteria:…”

“…To make the pencils according to the model described by Junior et al [44], we would require 60 USD to buy the sensors, 80 USD for the workforce and 560 USD for software licenses. On the other hand, if we used the design presented in Di Febbo et al [43], it would take 90 USD to buy the sensors, 80 USD for the workforce and 960 USD for software licenses.…”

A smart ink pen for spiral drawing analysis in patients with Parkinson’s disease

“…Parkinson's disease The goal of the work is to propose an alternative method to quantify spiral drawing. A smart ink pen, presented in [17] and designed to write on paper, was used by PD patients and healthy control for data acquisition during spiral drawing execution on paper. Data were then processed to extract relevant features and a statistical analysis was conducted to investigate between-group differences.…”
