While it all started in the cloud Artificial Intelligence is now moving at the very edge is ultra-low power nodes, and Microchip has launched two SAMD21 Arm Cortex-M0+ machine learning evaluation kits that now work with AI/ML solutions from Cartesiam, Edge Impulse, and Motion Gestures. Bot machine learning evaluation kits come with SAMD21G18 Arm Cortex-M0+ 32-bit MCU, an on-board debugger (nEDBG), an ATECC608A CryptoAuthentication secure element, ATWINC1510 Wi-Fi network controller, as well as Microchip MCP9808 high accuracy temperature sensor and a light sensor. But EV45Y33A development kit is equipped with an add-on board featuring Bosch’s BMI160 low-power Inertial Measurement Unit (IMU), while EV18H79A features an add-on board with TDK InvenSense ICM-42688-P 6-axis MEMS. The photo above makes it clear both SAMD21 machine learning evaluation kits rely on the same baseboard with a MikroBus socket connected to either 6DOF IMU 2click or 6DOF IMU 14 click add-on board from MikroElektronika. Both boards are similar, but the latter was just released this […]
Way back in 2012, I wrote about Microchip MGC3130 3D Gesture Controller with “GestIC technology” which allows you to make gesture up to 15cm from the surface and at lower power in order to control devices in a new way. At the time, the chip was said to sell for $2.26 in large quantities, and the evaluation kits went for $169 and up. I’m writing about MGC3130 about 5 years later, as Seeed Studio has started taking pre-orders for a $25.89 Flick HAT board based on the solution, and designed for Raspberry Pi boards, or other boards with a compatible 40-pin “GPIO” header featuring an I2C interface. Flick HAT 3D Tracking & Gesture HAT specifications & features: Chip – Microchip MGC3130 3D Tracking and Gesture Controller Tracking / Gesture Features 3D tracking Gesture sensing up to 15cm: Swipe (east to west, west to east, north to south, south to north), tap and double tap (center, east, west, north, south), airwheel […]
You can use advanced methods to implement gesture control using devices like Leap Motion, or a camera with a computer vision program like OpenCV, but if you have cost and size constraints, and can work with a limited number of gestures, Broadcom APDS-9500 proximity & gesture sensor might be a useful component as it comes in a 18-pin package, and supports up to 9 gestures. The chip also provides proximity detection for sensing objects approaching or departing. Avago / Broadcom APDS-9500 key features: Gesture output – 9 gesture recognition: g move up, move down, move left, move right, move forward, move backward, circle-clockwise, circle-counterclockwise and wave Proximity output – Object brightness output and size output Cursor mode output – X and Y output Range – up to 60 cm Image output – SPI output; 30 × 30 pixels / 60 × 60 pixels; 9-bit gray scale Ambient light immunity I2C-bus interface compatible with data rates up to 400 kHz Dedicated Interrupt pin Flexible […]
ZTE launched Project CSX last year in order to let anybody submit product ideas and/or vote for the best choices, and after several months, the winning entry was a phone with an adhesive backcover and eye-tracking function to control the phone without hands. The company has now named the phone ZTE Hawkeye launched a crowdfunding campaign on Kickstarter to raise funds for the development and manufacturing of the smartphone. Hawkeye smartphone specifications [Updated on Jan 18 with the released the specs]: SoC – Qualcomm Snapdragon 625 Octa-core processor @ 2.0GHz System Memory – 3GB RAM Storage – 32GB flash memory + micro SD slot up to 256GB Display – 5.5″ FHD (1920 x 1080) Audio – HiFi audio Connectivity – WiFi, Bluetooth, NFC, dual SIM card slot Camera – Rear: Dual Lens 13MP + 12MP with optical zoom; front: 8MP USB – 1x USB type C port Sensors – Fingerprint sensor Battery – 3,000 mAh with Quick Charge 2.0 The […]
The first thing you notice with Tbee TV box is the beehives inspired hexagonal enclosure, as we’ve already seen with T95Z Plus TV box, but the features that really stand out are voice command, and especially gesture control thanks to the built-in microphone and camera. Tbee TV box specifications: SoC – Amlogic S812 quad core Cortex A9r4 processor @ up to 1.99 GHz with octa-core Mali-450MP GPU System Memory – 2GB Storage – 8GB eMMC flash + SD card slot Video & Audio I/O – HDMI input, HDMI output Connectivity – 10/100M Ethernet, WiFi 802.11 b/g/n (2.4 GHz) and Bluetooth 4.0 USB – 2x USB 2.0 host ports Misc – IR receiver, built-in HD ready camera and IR receiver Dimensions – 28.5 x 8.5 cm (full package) Weight – 860 grams (full package) The box ships with an air mouse with QWERTY keyboard and its RF dongle, a HDMI cable, a power adapter, a micro USB cable, a stand, and […]
ZTE launched CSX Project last month in order to design a smartphone or other consumer product based on input from the community. People submitted ideas last month, and voted for the best ideas at the beginning of September, and the results are now in. There used to be a popular proposal to make a ZTE Ubuntu phone, but for some reasons since they may make one anyway, this has not been selected by the jury, and instead the three winning ideas are: Self-Adhesive Smartphone with Optimized User Interface via Eye Tracking System and Split Screen Technology Powerglove (Android application control of hands) VR – Interactive diving mask The first solution had by far the most votes, and the main purpose is to use the phone without touching it. Two laser-focused front cameras would track the eye movement to let the user scroll the screen with eye, while it’s been stuck to wall via its self-adhesive polymer back. The phone would […]
There’s a wide a virtual reality solution from cardboard kits that now sells for a couple of dollars to full featured headset with motion tracking selling for several hundred dollars or more. 3DiVi has designed a Kinect like motion tracking device that connects to your Android and iOS smartphone, and is supposed to offer similar tracking capabilities of more expensive head mount displays (HMD) such as HTC VIVE at about half the cost, while also replacing the cables of those kits with wireless connectivity through WiFi and Bluetooth 4.0 LE. The company offer three VicoVR devices part with the following specifications: VicoVR Sensor SoC – Unnamed Samsung Exynos processor Connectivity – Bluetooth 4.0 LE, WiFi 802.11 b/g/n Data stream Bluetooth – User pixel mask @ 30 fps, 3D coordinates up to 19 skeletal joints per user (max 2 users) @ 30 fps, 3D point cloud @ 30 fps up to 160×120, hand pointers and gestures WiFi – Bluetooth data + […]
A group of researchers of the Future Interface Group, Carnegie Mellon University in the US, has worked on SkinTrack technology which enables continuous touch tracking on the skin by using a ring emitting high frequency AC signal, and a sensing wristband with multiple electrodes. They’ve created sensor band and ring prototypes to demonstrate the technology. The ring includes an oscillator that generated a 80Mhz sine wave at 1.2Vpp. It consumes 7mA during operating meaning that they could get 15 hours out of the 100 mAh battery used in the prototype. The wristband features four pair of electrodes coupled with AD8302 RF/IF gain and phase comparator chips in order to derive X and Y coordinates from the phase of the signal. The sensing board produces eight analog values which are sampled by Atmel ATMega328 microcontroller’s 10-bit ADC inputs, and transmitted to the watch using a Nordic NRF8001 Bluetooth Low Energy (BLE) chip about 30 times per seconds. The video below further […]
