Their main concern is the need for experimented operators to insert the PL catheter and thereby limit complications.
However, using this PL method in daily practice seems difficult to us and this device must be used by experimented operators (usually surgeons) to limit the complications.
During the experiment, operator performances, such as completion time, error, secondary task, workload, and situation awareness, are measured and collected.
Immediately after each scanning session, the experiment operator had a short communication with the participants.
Specifically, in Müller et al.'s experiments DNA-looping assays involved operator sequences that were located on the E. coli chromosome, whereas in Becker et al.'s experiments, operator sequences resided on single-copy F' episomes.
In an experiment, operators controlled a mobile robot by steering to trace reference lines.
The model includes the attributes of the SP experiment, operator-specific dummy variables and three user characteristics.
Before the experiment, operators were showed the assistance types and informed that the system might provide assistance at the time of operation.
In one experiment, operators drove the course twice, once in a mode where the robot took no initiative and once in a shared control mode where the human felt like they were in control but the robot wove its way through hallways and openings.
As such, Elliott and his camera operator, Alan Perry, experimented with original angles and techniques, electing to introduce one scene with a long tracking shot and filming the characters using a mixture of live-action close-up shots and forced perspective.
