To show potential benefit as a general interface; The Earswitch prototype can be used with Switch ViaCam software to control Drumkit software https://www.microsoft.com/en-us/p/drumkit/9wzdncrfhw5v , as a handsfree drum control.
The SwitchViaCam can output definable keystrokes and Drumkit can be configured to accept these keystrokes to generate a drum beat handsfree; I guess like a bass drum with a pedal (clearly I am no musician!)
SwitchViaCam could also be used in a similar way for gamers ; for an extra handsfree control - its been suggested that could be used to replace “Push to Talk” and “Aim Down Site” view (although , again I am not a (recent) gamer)
In SwitchViaCam (MUST open as Adminstrator)
Config> Select USB Otoscope Camera (needs to be plugged in)
Enable Sensor - select box
Drag and expand selection box (blue box) to cover the middle of the eardrum (not shown here)
Decide on output keystroke in “Event type”
Alter Time Filter/Motion Detection Threshold (see below - alter to get required sensitivity)
Open - DrumKit or Game - & alter the keystroke required for the control input
Clearly it may be hard to get hold of the otoscope currently but if anyone lets me know how they have used this, I would be very grateful

Switch ViaCam is an image detection and keystroke output by Cesar Mauri which can be used instead of the combination of iSpy/Autohotkey script.
It needs to be in the Foreground in Windows for it to work with Grid3, but it is a lot more responsive that the iSpy/Autohotkey combo.
Some configuration of the camera settings may be needed for the Teslong otoscope, although the newer smaller 4x20mm otoscope worked with the default settings.
For Teslong I needed to change the camera configuration to the following to switch to the Teslong otoscope to prevent it crashing:
640x480 , capture speed 5 & a time filter of 500ms approx.
Below is a screen shot of the set up using the 4x20mm otoscope, the Decibullz moulded earplug and Switch ViaCam to type on Grid3 (Grid3 configured to use a "Tab" keystroke as the switch access)

Using the heat moulded Decibullz Custom Earplugs as the anchor for the smaller 4x20mm otoscope, and a silicon earphone tip; this gives a stable Earswitch that doesn’t move with speech or head movement but can control Grid3 with tensor tympani control.

Success with earshell and smaller otoscope
Attached shows drilled out Ear shell to fit the 4mm otoscope & below is a picture of the drum showing that the otoscope is directed in the correct position (although the camera was upside down!):
Although shows proof of concept it’s not currently stable in the ear as the wire is too inflexible and moves the shell out of position
I’ll try with a longer silicon ear tip as this may secure it better and protect the end of the otoscope .
