  In this preliminary study, we investigate changes in handover behaviour when
transferring hazardous objects with the help of a high-resolution touch sensor.
Participants were asked to hand over a safe and hazardous object (a full cup
and an empty cup) while instrumented with a modified STS sensor. Our data shows
a clear distinction in the length of handover for the full cup vs the empty
one, with the former being slower. Sensor data further suggests a change in
tactile behaviour dependent on the object's risk factor. The results of this
paper motivate a deeper study of tactile factors which could characterize a
risky handover, allowing for safer human-robot interactions in the future.
