ABSTRACT There is tremendous potential for developing mobile-based occupational productivity tools for semi-literate and illiterate users in India. One-handed thumb use on the touchscreen of smart phone or touch phone is considered as an effective alternative than the use of stylus or index finger, to free the other hand for supporting occupational activity. In this context, usability research ...

There is a tremendous potential for developing mobile-based productivity tools and occupation specific applications for the semi-literate and illiterate users in India. One-handed thumb use on the touchscreen of smart phone or touch phone is considered as an effective alternative than the use of stylus or index finger, to free the other hand for supporting the occupational activity. In this con...

Kalimbo is an extended kalimba, built from repurposed materials and fitted with sensors that enable it to function as a reductionist control interface through physical gestures and capacitive sensing. The work demonstrates an attempt to apply theories and techniques from visual collage art to the concept of musical performance ecologies. The body of the instrument emerged from material-led maki...

This paper proposes H, an anthropomorphic prosthesis hand with 5 fingers and human hand size. It consists of the combination of direct actuated and underactuated system for a dexterous grip. The H also has modularized 2 DOF of MCP mechanism in a thumb for power grip. The adduction-abduction and antepositon-retroposition movements are generated by this structure of thumb which is the function of...
