7. 스마트 웨어러블 시장의 극복요소
• 웨어러블 디바이스가 ICT산업의 새로운 성장동력이 될 것으로 기대하고 있으나
– 다양한 하드웨어적인 기술적 제약들이 남아 있고
– 웨어러블 기기에 적합한 킬러 콘텐츠가 절대적으로 부족한 상황임
7
응용 및 활용성 요소 • 플랫폼 종속성이 강해 서로 다른 OS 기기간 활용할 수 없음
• 웨어러블 기기에 적합한 킬러 콘텐츠가 부족
• 다양한 응용들 사이에서 효과적으로 연계 활용할 수 없음

31. [4] ISO/IEC JTC1 SC41
• AHG on Wearables meeting
– Currently, the main gaps are the following:
• Service platforms: No service platform stands out in the field of Smart
Wearables. Also, no specific service platform has been deployed
specifically for Smart Wearables.
• Connectivity: Different networking and communications standards are
used for Smart Wearables. Short range communications technologies are
often used.
• Data interoperability: A lack of global data model and/or translation
mechanisms between different specific models is clearly a big issue.
• Devices certification: as Smart Wearables are electronics to be closer to
the human body, clinical certification of devices is an issue. Moreover, the
certification process of the whole wearable device does not allow rapid
innovation. Standards for incremental and modular certification are
needed.
• Devices modularity: No real standard targets the device modularity, i.e.
the ability to add/remove hardware capabilities to a device.
• Security and privacy: Since Smart Wearables devices are dealing with very
sensitive and personal data. Security and data privacy standards are
necessary. The lack of these standards prevents user acceptability from
both enthusiasts and rejecters.
