The terms, being all the rage and jumping on the bandwagon describe the psychological responses of consumers, or individuals. They do not describe manufacturers's dilemma. Olympus are not jumping on the wearable camera bandwagon, as DPReview claim. Their patent describes the intent to enter a growing consumer market and carve their own niche.
Investopedia defines 'bandwagon effect' like this: "A psychological phenomenon whereby people do something primarily because other people are doing it, regardless of their own beliefs, which they may ignore or override."
Wearable technology, a decades-old market, got a shot in the arm when phones smartened up. Olympus, and other companies entering that market is evidence of sustaining innovation. Prices will fall, technology will improve; inevitably the market will saturate.
Eventually, disruptive innovation will pitch the current market to one side, at which point DPReview or someone else, will call a related patent or product, a bandwagon. Will it be a Google Glass-like device like the one described in this patent [found by 4/3 Rumors]? Are we ready for conspicuous wearable technology?
