Cursor deflection?

Question

I'm reading a relatively technical document related with issues around wireless interference and came across with the phrase "cursor deflection." What does it mean? I imagine that it would be like a phenomenon where a mouse cursor moving across a display without any input (and/or ignoring it) but not sure due to my luck of technical knowledge in this area. A Google search simply directed me to a few way-too-technical documents but, considering the context from which I picked up the phrase, I presume the phenomenon itself is not so special and that it can be experienced by end-users.

Any help appreciated. Thank you.

Can you post the document or at least the entire paragraph? It's really hard to tell you what they mean without enough context.

Thanks for the reply. The below is the paragraph in question.

"There are several challenges to overcome when integrating wireless
capabilities into notebook computers. Due to the rapid adoption of wireless
enabled devices such as cellular phones, notebook vendors have
experienced a variety of issues when these RF devices are placed in close
proximity to notebooks. Documented cases from end-users have shown
that the interaction of the RF device and the notebook has adversely
affected the performance of both devices. For this reason, notebook vendors
have been fighting to keep unwanted RF sources and noise from
entering or exiting the notebook. Now the industry is actually attempting
to integrate these RF technologies inside the notebook.
A recent study done by Notebook Computer Research Institute (NCRI)
revealed some of the potential issues that can arise with RF interference
in notebooks. For example, audible buzzing in the Audio sub-systems,
cursor deflections across the LCD panel, dimming or flickering of LCD
backlights, and increased modem data error rates or dropped connections."
