- Abstract
- The objective of this paper is to develop and evaluate
a directional vibrotactile feedback interface as a guidance tool for
postural adjustments during work. In contrast to the existing
active and wearable systems such as exoskeletons, we aim to
create a lightweight and intuitive interface, capable of guiding
its wearers towards more ergonomic and healthy working
conditions. To achieve this, a vibrotactile device called ErgoTac is
employed to develop three different feedback modalities that are
able to provide a directional guidance at the body segments
towards a desired pose. In addition, an evaluation is made to find
the most suitable, comfortable, and intuitive feedback modality
for the user. Therefore, these modalities are first compared
experimentally on fifteen subjects wearing eight ErgoTac devices
to achieve targeted arm and torso configurations. The most
effective directional feedback modality is then evaluated on
five subjects in a set of experiments in which an ergonomic
optimisation module provides the optimised body posture while
performing heavy lifting or forceful exertion tasks. The results
yield strong evidence on the usefulness and the intuitiveness of one
of the developed modalities in providing guidance towards
ergonomic working conditions, by minimising the effect of an
external load on body joints. We believe that the integration of
such low-cost devices in workplaces can help address the wellknown and complex problem of work-related musculoskeletal
disorders.
