Hapti
c, or tou
ch is omnipresent of everyday human a
ctivity and provide
continual and essential sour
ce of information during the performan
ce of virtually any physi
cal a
ctivity. A new multimodal human-ma
chine interfa
ce ¡°
haptic controlled excavator¡± that uses tou
ch is
currently being developed to in
corporate hapti
cs into the design of human-ex
cavator interfa
ce. Hapti
cs, has great potential to in
crease effi
cien
cy if properly integrated into the hapti
c controlled ex
cavator interfa
ce. One of the diffi
culties in developing the new hapti
c controlled ex
cavator interfa
ce has been how to determine the range of for
ce feedba
ck values that produ
ce the best operator performan
ce. Range of for
ce feedba
ck was
classified as
no feedback,
low feedback,
medium feedback or
high feedback based on a pilot study. An empiri
cal study was then
condu
cted using twenty subje
cts to investigate the range of for
ce feedba
ck that yields best operator performan
ce. The results show that
medium for
ce feedba
ck range produ
ced the best operator performan
ce, although this differen
ce was not statisti
cally signifi
cant.

In this research, an empirical study was conducted to investigate the range of force feedback that is necessary for best operator performance in the haptic controlled excavator. Results from this study will help to develop efficient haptic controlled excavator interface with proper level of force feedback, and in turn improve the human-excavator interaction.
