Ignore the sarcasm.
What do you mean by gimmick?
Obviously, you can't mean the mechanical definition (a device for controlling gambling apparatus, or more generally any novel gadget).
If you mean, as Merriam-Webster defines it, "an ingenious and unusally new scheme or angle," then YES, PhotoReading is a gimmick for understanding writtian information at least three times faster than regular word-for-word reading, and is much easier and more playful than speed reading.
Please, be precise with your language when asking questions to Kaidens. Kaidens are very doctrinaire by nature, and will argue about the definition of a thing much more enthusiatically than about the thing itself.
