 DIGITAL  ANTROPOMETRIC  HAND  MEASUREMENT

According to Ovidio Rincón's Phd thesis, the existing size of leather gloves for heavy working doesn’t fit to the hands of the latin american population. Taking that premise as starting point, this research project inquires in the need of a digital anthropometric measuring system that can define patterns for any hand, and with this create perfect size gloves for workers.

The Hand of Need

RESEARCH  /  PROTOTYPING  /  SOCIAL DESIGN

A big problematic in many heavy work duties is that the workers don’t use the protective gear because this is uncomfortable for them and it makes their routine something painful or slow, which lead to health risks and to a possible dismissal. However, doing this dangerous work without any protection is a bigger threat that can lead them to a disembodiment or even death. In his thesis, Ovidio makes visible that the hands of the latin american population specifically the Colombian, have indeed a different hand morphology that doesn’t match the glove sizes available in the market. Ovidio propose a sizing system which include the anthropometric measurement of a wide range of Colombian hands. However, besides the system works perfect with Colombian hands, it cannot be implemented for a different culture. What about an Ugandan hand? Or an Hawaian one? Thus, this system could be improved using digital tools such as image analysis and digital fabrication machines. That’s where this project finds its reason to be.

This project proposed by the Icesi University’s Leonardo research group delve into the design of gloves for heavy duty work that fits perfectly the hand of its user.The project is divided in two major parts: the fabrication of an ergonomic leather glove that is both comfortable and resistant for heavy duty work, and the digital anthropometric measurement of the hand which will generate patterns for the construction of the glove and an approximate 3D model of the user’s hand.

Developing Measures

DIGITAL FABRICATION LEADER  /  DEVELOPER  /  RESEARCHER

My role was the design and programming of the digital anthropometric measurement system. At the date, the whole system is programmed using Java language improved with Processing and Processing’s Opencv and OscP5 libraries. After many tries to detect the hand using a webcam and the Java’s Opencv library, I decided to implement a system of markers across the essential anthropometric measures defined by A. Yu, K.L. Yick, , S.P. Ng, J. Yip in their paper “2D and 3D anatomical analyses of hand dimensions for custom-made gloves”. The markers refers to “the hands skeleton” which is a series of green elastic bands attached to a silhouette of a generic hand. In this way, any user will be capable to fit the elastic bands to their hands and with this, give us the real measures of their hand. The hand is scanned using a desktop scanner and then the elastic bands are analyzed with Opencv, which creates blobs for each band, allowing to find distances in a pixel level. The pixels values are later converted to millimeters and send to Grasshopper via open sound protocol (Oscp5), where the data is gather to generate an approximate 3D model of the user’s hand.
