Senbay is a new media using a sensor data embedded video for sharing experiences. By using Senbay Camera, we can generate a sensor data (e.g., location, heart-rate, and air-pressure) video easily. In addition, the video (Senbay Video) can be quickly shared via existing web services such as video streaming services, SNS, and chart tools. Moreover, sensor data that are embedded in the video are stored as reusable format, then all of the audiences can utilize the data flexibly with synchronized video by Senbay Reader.


Like recording a video, Senbay Camera can generate a sensor embedded video (Senbay Video) easily.


Senbay Video can be shared via existing web services, and managed synchronized sensor data and video simply.


Using the embedded sensor data on the Senbay Video, Senbay Reader produces rich video experiences.

Use Case

Using Senbay, you can record, share, and utilize a sensor data embedded video easily. For example, (1) Senbay Camara on a smartphone allows recording a view from a bike with physical motion/condition data (such as speed, location, vibration, and heart-rate) by just push a record button. (2) Also, you can share the video via common web services like YouTube to all over the world. (3) In addition, audiences can visualize the embedded data as a map, chart, and animation flexibly. (4) Developers can extend the sensing/utilizing method using the Senbay Developer Libraries.
