$99 Mira Prism Augmented Reality Headset Works with your Phone

July 19th, 2017 7 comments

We’ve seen many virtual reality headsets launched in the last year or so, even through the technology and ecosystem still needs to be improved to offer an acceptable user experience, but so far I have not seen augmented reality headset that combines 3D real and virtual worlds into a single screen. I was pretty enthusiastic about augmented reality technology when I first heard about in 2010,  but fast forward to 2017, I’m not using any such apps myself, with the most popular AR app possibly being Pokemon Go game launched last year, and apps like the upcoming AR Measure look quite useful. Augmented reality normally works by holding your phone into your hands and the camera, but Mira Prism will change that it’s meant to be worn like a virtual reality headset and relies on a phone (iPhone only for now) to mix both worlds right in front of your eyes.

The headset includes a semi-transparent screen allowing you to view the real world, and also reflects the phone screen to mix your view with virtual objects. The Prism is also said to feature 6 degrees of freedom optical tracking and a wireless controller with gyroscope & accelerometer, a touchpad, and buttons. It only supports iPhone 6 / 6s / 7 phones, and I have not really been impressed by the demo in the promo video, although the people seem to have a lot of fun, as the virtual objects look somewhat pale due to the semi-transparent screen…


But that’s all new and an interesting concept, so we’ll have to see how that evolves. The main advantage I see is that when you play in groups, you can still interact with other people. Mira Prism is also not too expensive with pre-orders going for $99 on Mira Reality website. Note that you’d need to wait until the end of the year to receive the headset, and price may go up to $149 after that. It’s also mostly targeted at developers right now, since few AR apps are available.

Qualcomm Snapdragon Wear 1200 Platform for Wearables Supports LTE Cat M1 and NB1 (NB-IoT)

June 28th, 2017 No comments

After Snapdragon Wear 2100 and 1100 launched last year , Qualcomm has announced a new Snapdragon Wear 1200 platform still designed for wearables, but with lower power consumption, less processing power, a more compact package, and built-in support for LTE IoT communications standards such as LTE Cat M1 and LTE NB-IoT (Cat NB1).

 

Qualcomm Snapdragon Wear 1200 key features and specifications:

  • CPU – ARM Cortex A7 @ 1.3 GHz
  • Memory / Storage – Support for discreet or MCP NAND and LPDDR2
  • Display – Support via SPI for simple UI and displays
  • Modem
    • Global multi-mode supporting Cat-M1 / NB1 / E-GPRS.
    • Supports LTE FDD and TDD for Cat-M1 and E-GRPS and FDD only for Cat-NB1
    • Up to 300 kbps downlink and 350 kbps uplink for Cat-M1
    • 10 kbps download and 60 kbps upload speeds for Cat-NB1
    • Integrated voice support for VoLTE
  • Other Connectivity – Pre-integrated support for Qualcomm 11ac Wi-Fi and Bluetooth 4.2 / Bluetooth Low Energy
  • Location
    • GLONASS, Galileo, and BeiDou constellations supported
    • Accurate Wi-Fi and cellular positioning, optimized for Cat-M1/NB1
    • Low power Geo-Fencing
    • Qualcomm Cloud Based Location Services with   day GNSS predicted orbits service, Qualcomm end-to-end Global Terrestrial Positioning (GTP) Wi-Fi
      and cellular service
  • Security
    • Qualcomm Trusted Execution Environment
    • Wireless protocol security
    • Hardware based security with Secure Boot/storage/debug, hardware crypto engine, hardware random number generator, and Trustzone
  • Power Management
    • Ultra-low Rock Bottom Sleep Current (RBSC) for extended standby
    • Power Save Mode (PSM)
    • Extended Discontinuous Receive (eDRX)
    • Charging – Companion charging chipset
  • Package / Process – 79mm2 package; 28nm manufacturing process

The product brief actually mention an ARM Cortex-A1 core, but this must be a mistake, as later on Qualcomm explains the platform is cost-optimized to reduce the BOM and NRE with an ARM Cortex A7 core “eliminating the need for MCUs” . The company also claims the solution is scalable thanks to broad software re-use, and the possibility to add voice, WiFi, and Bluetooth. The solutions is also said to last 10 day on a charge with LTE standy, when paired with 350 mAh battery and using eDRX.

Linux and ThreadX operating systems will be supported, and while Wear 1200 chipset is supposed to target wearables such as kid, pet, elderly, and fitness trackers, I’d assume it might also be useful for some IoT applications like GPS trackers provided it’s cost-effective. Reference designs from Borqs and Quanta are available in order to allow manufacturers to bring products to market quickly. You may be able to find a few more details on Qualcomm Snapdragon Wear 1200 product page.

Samsung S-Patch3 Wearable Health Tracker Based on Samsung Bio-Processor Hits the FCC

June 9th, 2017 No comments

At the end of 2015, Samsung unveiled their S3FBP5A Bio-Processor comprised of an ARM Cortex-M4 MCU, a DSP, and sensors for PPG, ECG (electrocardiography), Skin temperature, BIA, and GSR to have a single package to design tracker able to monitor your health condition. The company demonstrated an early prototype called S-Patch at CES 2016 (See embedded video at the end of this post), and now S-Patch3 wearable health monitoring system has just hit the FCC.

The system has two round shapes case connected via a cable, with one for the battery compartment, and the other containing the Bio Processors, and meant to be placed on your chest. The device can then synchronize the data with your smartphone in real-time over Bluetooth. People with heart conditions may benefit from the system, as if they wish to do so, they could share the data with their doctor. Few documents are publicly available on the FCC website, and while we don’t know the expect launch date of the device itself, the user’s manual and photos will be released on December 3rd, 2017 on the FCC website, which should roughly correspond to the launch date, or at least the official announcement date from Samsung.

Think Silicon Ultra Low Power NEMA GPUs are Designed for Wearables and IoT Applications

May 8th, 2017 1 comment

When you have to purchase a wearable device, let’s say a smartwatch or fitness tracker, you have to make trade offs between user interface and battery life. For example, a fitness tracker such as Xiaomi Mi Band 2 will last about 2 weeks per charge with a limited display, while Android smartwatches with a much better interface need to be recharged every 1 or 2 days. Think Silicon aims to improve battery life of the devices with nicer user interfaces thanks to their ultra-low power NEMA 2D, 3D, and GP GPU that can be integrated into SoCs with ARM Cortex-M and Cortex-A cores.

Nema|t 3D GPU Block Diagram

The company has three family of GPUs:

  • NEMA|p pico 2D GPU with one core
    • 4bpp framebuffer, 6bpp texture with/out alpha
    • Fill Rate – 1pixel/cycle
    • Silicon Area – 0.07 mm2 with 28nm process
    • Power Consumption – leakage power GPU consumption of 0.06mW; with compression (TSFSc): 0.03 mW
  • NEMA|t tiny 2D & 3D GPU with one to 4 cores
    • 4bpp framebuffer, 6bpp texture with/out alpha
    • OpenGL ES support
    • Can render a 420×420 3D UI @ 80 MHz
    • Fill Rate – 1-4pixel/cycle; up to 1,600 MPixel/s for the quad core version  @ 400 MHz
    • Silicon Area – 0.1 to 0.25 mm2 with 28nm process
    • Power Consumption – leakage power GPU consumption of 0.07mW; with proprietary compression technology (TSFBc, TSTXc): 0.03 mW
  • NEMA|s GPGPU with one to four cores
    • Supports Network On Chip (NoC) interconnect for clusters with each cluster supporting up to four cores, and each core handling up to 128 threads
    • Fill Rate – 1pixel/cycle
    • Silicon Area and Power Consumption – TBA, as Nema|s is only implemented via FPGA for now

NEMA|s GPU

The first two models are available right now, while the third is still in development. The company is also working on the fourth family with NEMA|ts “tiny small” GPU, but no details have been provided.

Provided the website is up-to-date, NEMA|p 2D GPU is supported in FreeRTOS V8.0.1 and Linux kernel 3.x, while NEMA|t can be used in Linux 3.x and Android 4.x. The company also provides a software library in ANSI C, as well as DirectFB and Qt support.

I found out about the NEMA through a Charbax video at Mobile World Congress 2017.


Think Silicon GPUs are said to be already used in Microchip and Dialog MCUs, and Sequant recently announced an “LTE for IoT System-on-Chip” with a NEMA|p 2D/2.5D GPU. The demo in the video above also shows an Ambiq Micro board connected to an FPGA implementation of one of their GPUs. You’ll find more information on Think Silicon website.

$100 Xiaomi “90 Minutes Ultra Smart Running Shoes” are Equipped with Intel Curie Module

March 29th, 2017 2 comments

If you’ve ever used a fitness tracker on a wristband, you must know that although it gives an indication of your level of activity, it’s usually not really accurate to count steps. Xiaomi’s “90 Minutes ultra smart running shoes” fixes the issue as the fitness tracker powered by Intel Curie module is placed right inside the shoes.

Most of the information is in Chinese, and I could only find limited specifications for the shoes:

  • Size – 39 to 45
  • Intel Curie Module based on Quark SE SoC with 6-axis accelerometer and gyroscope, Bluetooth 4.0 LE connectivity
  • Battery – Good for 60 days on a charge
  • Material
    • Shoe sole – Rubber
    • Shoe vamp – Fabric + Synthetic leather
    • Shoe insole – Antibacterial removable air cushions

The small device based on Intel Curie module resides inside the sole, stores fitness data such steps, distance covered, speed, (estimated) calories burnt, etc… It’s unclear whether it will be charged wirelessly, or some charging port is available on the shoes.

You’ll allegedly get all that fitness data using Mihome app by connecting over Bluetooth 4.0 LE, and the app will be able to differentiate between walking, running, and riding a bicycle.

Xiaomi’s smart shoes have been selling for 299 RMB ($44) via a Crowdfunding campaign in China, but GeekBuying is already taking pre-orders for the shoes for $99.99 including shipping with delivery scheduled for mid April.

Omron Project Zero 2.0 is a Thinner Wrist Blood Pressure Monitor & Smartwatch

January 11th, 2017 3 comments

Omron Project Zero BP6000 blood pressure monitor & smartwatch / fitness tracker was unveiled at CES 2016. The device was due to be released at the end of 2016 pending FDA approval, but the launch has now been delayed to spring 2017, and it will be sold under the name “HEARTVUE”. The company has however showcased a new version at CES 2017, for now just called Omron Project Zero 2.0 that has the same functions but is more compact and lightweight.

The watch will also work with Omron Connect US mobile app, and can record accurate blood pressure, as well as the usual data you’d get from fitness trackers including activity (e.g. steps) and sleep, as well as smartphone notifications. Blood pressure measurement can be activated by the user by pressing a button and raising his/her wrist to the height of the chest. The goal is the same as the first generation watch: to make people who need it measure their blood pressure in a more convenient fashion. The second generation device looks much more like a standard wristwatch as the company reduced the size of the inflatable cuff.

blood-pressure-smartwatchThe new model will also have to go through FDA approval, a time consuming process, and Omron Healthcare intends to release the device in 2018 for around $300. More details about the new model may eventually show up on the company’s Generation Zero page.
