Deeper Smart Sonar Fishfinder – Fish will hate your Smartphone!

The idea of this project is completely crazy, Deeper Smart Sonar enables your smartphone to detect fishes and any underwater objects, by using a Bluetooth sonar sphere. This waterproof sphere transmits fish depth and location info, along with temperature and floor depth to your Android or iOS smartphone or tablet within 150 feet via Bluetooth. One battery load lasts for at least six-hours which should suffice for a long relaxing fishing session.

SoftKinect announced mini HD gesture recognition camera

SoftKinetic announced world’s smallest HD gesture recognition camera and releases a middleware for far and close interactions. A professional developer kit will be available in order to start to develop new generation gesture-based user interfaces and applications.

SoftKinect is one of the pioneer providers for 3D vision and gesture recognition systems. They announced the DepthSense 325 (DS325) sensing device which is a mini HD camera that senses in 3D (depth) and in HD standard 2D (color). The DS325 uses a time-of-flight (TOF) cmos sensing camera system to detect gestures in 3D space. This camera is able to operate from as close as 10cm and includes a high-resolution depth sensor with a wide vield of view, combined with 2 microphones.

 

AirTiles: a Flexible Sensing Space

AirTiles is called a “flexible sensing space”. Using a series of electronic disks that contained a laser, infrared input and output ports, and a range-finding sensor, the modules could become aware of each other and the space between them. Each were slightly smaller than a cereal bowl, and could be easily picked up and moved around.

To set them up, the first AirTile is activated by pressing a small button, which activates a single laser beam that is drawn onto the floor. When a second AirTile is placed within the first’s laser beam, it also activates and in turn fires off another laser. At this point, multiple modules can be chained together until the originating tile receives the terminating beam from the final module in order to create a triangle, square, etc.

Once a pattern of tiles is achieved, the space inside is then tracked by all the tiles. If something blocking their vision, such as a hand, a shoe, or other intrusion is introduced, the tiles will blink and make an auditory sound effect. While this may seem strange at first, I could easily see similar devices created for security systems, gating in outdoor pets with virtual fences, or even in a toddler’s play area.

Below: I show how to set up the AirTiles together by “chaining” the lasers together. While I chained them properly, I didn’t quite get the square array to detect my hand. However, the triangle array next to it sensed my hand properly by flashing and beeping.
