Well the one I have is round and about the size of a silver dollar so it could easily fit in a shirt pocket. I haven't actually used it for the purpose of capturing ideas yet but I would imagine that in a shirt pocket one could activate it while walking, simply by speaking out loud. In a shirt pocket I would think that would be close enough to activate it? Although you might get wierd looks from people to whom it might appear you are speaking to yourself. Then again in this day and age of wireless bluetooth headsets for your phon, people might not think twice and just assume you're talking to someone on your cellphone.How does a voice-activated recording device with a built-in microphone affect its usability for capturing spontaneous ideas during activities like long walks, and what ethical considerations should be taken into account when using such devices to secretly record conversations without others knowing?
As for ethical considerations that is pretty much up to the individual and the laws of the state you live in. People have an amazing ability to justify things they think are right or just so it would depend on what purpose you were recording for. If it's just to capture your own thoughts then I see noethical considerations at all. if however it is to secretly capture someone elses words without their knowing then I would say it depends on who they were and what was your plans on what to do with the recording. Like the woman who made th news recently for secretly recording supreme court judges responding to what they believe is a sympathetic person at an event where they should be able to expect they're not being secretly recorded, that seems wrong because the information is gathered under false pretense. If it's in pursuit of gaining an admission to some crime that can be used by police or in court, then I would say it depends on that crime. For example if a person could gain a confession to a crime such as rape or murder I wouldn't have a problem with that. If however it was being used to capture someone admitting they grew cannabis in a state where that is not allowed then that seems wrong as that is a victimless crime. As far as legalities that's where the state your in becomes a factor. In some states it's perfectly legal to make secret recordings as long as one person is aware, even if that person is the one recording. In other states the laws require all parties to be aware and if they weren't that recording would be useless as evidence of anything and could not be used in court.
