We describe the status of the development and testing of the star tracking telescope for Gravity Probe B. The fused quartz telescope with an aperture of 14 cm and 3.8 m effective focal length is attached to the gyroscope housing and continuously points to a guide star.
When prompted by the experimenter, they closed their eyes and continuously pointed to the target as they walked past it.
First, in order to establish baseline pointing behaviour under full-cue conditions, participants viewed the target from the starting position and then continuously pointed to it as they walked past it with their eyes open (Sighted Walking: SW).
They continuously pointed at the spatial image of the target throughout the trial.
During the imagined walking condition, the task was identical, except that participants first viewed the target, closed their eyes, and continuously pointed at the remembered position of the target as they imagined walking past it on a straight, forward trajectory.

Since this system did not develop continuously from one point to the next we divided it into several trajectories representing the various possible processes.
This continuous pointing method requires participants to view a target and continuously point towards it as they walk, or imagine walking past it along a straight, forward trajectory.
Bilton continuously points out his willingness to help out friends and co-workers financially as well, with no desire for return.
The oil industry is right to point to the continuously rising global demand for oil; but the answer cannot be an ever-expanding supply produced in ever more hazardous ways.
