Is there any WEARABLE SENSORS available that can simulate human emotions ?
Something like the one in this link https://www.technologyreview.com/s/421316/sensor-detects-emotions-through-the-skin/ (but it doesn't capture many of the human emotions).
I am looking for some WEARABLE sensor that should simulate the level of Anger, Disgust, Fear, Happiness, Sadness, Surprise, Excitement etc of a human at any particular instance. I am NOT looking for emotion detection from Facial expression or voice recognition.
Your Help is much appreciated !! Thanks.
Take a look at the Frauenhofer Shore Software. Frauenhofer creating really great things like mp3. But i think this Software would be really expensive.

For my university project I must develop a windows app which recognises a user based on two biometrics - fingerprint and facial heat signature. This is very new and exciting territory for me as I will encounter difficult challenges that I have not yet faced and the learning curve will be very steep but fruitful.
My question relates to the camera which I will attempt to use for facial heat signature recognition. This is it: http://support.logitech.com/en_us/product/brio
It is relatively new and Logitech have not released any dev SDK for it and as such I am stuck on how to get under its hood/bonnet and integrate it with my app. I am looking for advice on how I can go about doing it and assess whether it is feasible, in any case. If it is not then I can not afford to waste my time on it and will have to come up with new ideas.
As an aside, it can be used for Windows Hello.
In short, I am looking for advice on how I can approach this challenge or whether I should at all. Thank you.
Try to access through MediaCapture and MediaFrameSource classes. It works for me. But its only 340x340 30fps camera. And IR diode blinking about 15-20 Hertz so there is blinks in IR frame.
C# used.
I am right now working on one application where I need to find out user's heartbeat rate. I found plenty of applications working on the same. But not able to find a single private or public API supporting the same.
Is there any framework available, that can be helpful for the same? Also I was wondering whether UIAccelerometer class can be helpful for the same and what can be the level of accuracy with the same?
How to implement the same feature using : putting the finger on iPhone camera or by putting the microphones on jaw or wrist or some other way?
Is there any way to check the blood circulation changes ad find the heart beat using the same or UIAccelerometer? Any API or some code?? Thank you.
There is no API used to detect heart rates, these apps do so in a variety of ways.
Some will use the accelerometer to measure when the device shakes with each pulse. Other use the camera lens, with the flash on, then detect when blood moves through the finger by detecting the light levels that can be seen.
Various DSP signal processing techniques can be used to possibly discern very low level periodic signals out of a long enough set of samples taken at an appropriate sample rate (accelerometer or reflected light color).
Some of the advanced math functions in the Accelerate framework API can be used as building blocks for these various DSP techniques. An explanation would require several chapters of a Digital Signal Processing textbook, so that might be a good place to start.
I am a ME undergrad and am designing an implant device that requires programming knowledge. I honestly have no idea how to get started and am looking for advice. Basically what I need is a way to control a stepper motor. Stepper motor's use steps (pulses) to rotate the gear head. Now this motor I'm using needs 20 steps to revolve once. I need to be able to control the # of steps I want in a day per say. The motor I'm purchasing comes with an encoder which I'm guessing connects to the circuit board. Now what I want to do is have an external control (like a remote control for a toy)that can set these rates. I don't know anything about radio transmitters, or how to program the circuit board to do this for me. Any help would be appreciated, or books I can look into, websites, or tutorials. Thanks.
There are many ways of solving this problem, but it is more of a systems engineering question than a programming question; until you know what the system looks like, there is no way of determining what parts will be implemented in software. More details would be required to provide a specific answer.
For example what are the security/safety considerations?
What wireless technology do you need to use? e.g. RF or IR, if RF then licensing may be an issue, and that may vary from country to country. You could use BlueTooth, ZigBee, or even WiFi, but these technologies are probably more expensive and complex than necessary for such a simple application. If IR then is immunity from interference from TV remotes or PC IrDA ports or similar required?
If the commands/signals from the remote are complex you will probably need both the remote and the motor driver to incorporate a micro-controller and software. On the other hand if you just need increase/decrease functions then it would be entirely possible to implement the remote functionality you describe without any processing at all (depending on teh communication technology you choose).
What is the motor encoder for? Stepper motors do not normally need an encoder since the controller can simply count steps executed in either direction to determine position. Is the encoder incremental or absolute? If it is incremental, then it is certainly not needed; if it is absolute than it may be useful if you need to know the exact position of the motor on power-up without having to perform an initialisation or requiring end-stop switches.
You mentioned a "circuit board"; what hardware do you already have? What does it do? Do you have documentation for it? If it is commercially available, can you provide a link so we can see the documentation?
As you can see you have more system-level design issues to solve before you even consider software implementation, so the question is not yet ready to be answered here on SO. I suggest you seek out your university's EE department and team-up with someone with electronics expertise do design a complete system, then consider the software aspects.
Well worth taking a look at the Microchip site:
http://www.microchip.com/forums/f170.aspx
They produce microcontrollers that can be programmed to do exactly what you require (and a lot more).
It seems that a lot of small business people have a need for some customized embedded systems, but don't really know too much about the possibilities and cannot quite envisage them.
I had the same problem when trying to explain what Android could do; I was generally met with glazed eyes - and then I made a few demos. Somehow, being able to see something - to be able to touch it and play around with it – people have that cartoon lightbulb moment.
Even if it is not directly applicable to them, a demo starts them thinking about what could be useful to them.
The sort of person I am talking about may or may not be technical, but is certainly intelligent, having built from scratch a business which turns over millions.
Their needs are varied, from RFID or GPS asset & people tracking, to simple stock control systems, displays, communications, sometime satellite, sometimes VPN or LAN (wifi or RJ45). A lot of it needs a good back-end database with a web-site to display, query, data-mine …
So, to get to the question, I am looking for a simple project, or projects, which will cause that cartoon lightbulb moment. It need not be too complicated as those who need complicated solutions are generally tech-savvy, just something straightforward & showing what could be done to streamline their business and make it more profitable.
It would be nice it if could include some wifi/RJ45 comms, communicate across the internet (e.g not just a micro-controller attached to a single PC – that should then communicate with a server/web-site), an RFID reader would be nice, something actually happening (LEDs, sounds, etc), plus some database, database analysis/data-ming – something end-to-end, preferably in both directions.
A friend was suggesting a Rube Goldberg like contraption with a Lego Mindstorms attached to a local PC, but also controllable from a remote PC (representing head office) or web site. That would show remote control of devices. Maybe it could pick up some RFID tags and move them around (at random, or on command), representing stock control (or maybe employee/asset movement within a factory or warehouse (Location Based Services/GIS)), which cold then be shown on the web site, with some nice charts & graphs etc.
Any other ideas?
How best to implement it? One of those micro-controller starter kites like http://www.nerdkits.com/ ? Maybe some Lego, or similar robot kit, a few cheap RFID readers … anything else?
And – the $409,600 question – what's a good, representative demo which demonstrate as many functionalities as possible, as impressively as possible, with the least effort? (keeping it modular and allowing for easy addition of features, since there is such a wide area to cover)
p.s a tie with an Adroid slate PC would be welcome too
Your customers might respond better to a solid looking R/C truck which seeks RFID tags than to a Lego robot. Lego is cool, but it has a bit of a slapped-together 'kiddie' feel.
What if you:
scatter some RFID tags across the conference room.
add a GPS & wifi transmitter to your truck.
drive the truck to the tag
(manually - unless you want to invest a lot of time in steering algorithms).
have a PC drawing a real-time track of the trucks path.
every the truck gets within range of the tag, add it to an inventory list on the screen, showing item id, location, time recorded, total units so far.
indicate the position of the item on the map.
I'd be impressed.
Is it 'least effort'? I don't know, but I'd hope that if this is the type of solution you are pitching, that you already have a good handle on how to read GPS and RFID devices, how to establish a TCP or UDP connection with wifi, how to send and decode packets. Add some simple graphics and database lookup, and you are set.
Regarding hardware, I don't have any first hand experience with any of these, but the GadgetPC Wi-Fi G Kit + a USB RFID reader + a USB GPS reciever looks like a nice platform for experimenting with this.
Many chip manufactures have off-the-shelf demo boards. Microchip has some great demo boards for TCP/IP communications on an embedded system. I haven't seen one yet for RFID. Showing potential customers some of these demos could get them thinking about what is possible.
I'd like to start messing around programming and building something with an Arduino board, but I can't think of any great ideas on what to build. Do you have any suggestions?
I show kids, who have never programmed, or done any electronics before, to make a simple 'Phototrope', a light sensitive robot, in about a day. It costs under £30 (GBP) including Arduino, electronics and off-the-shelf mechanics. If folks really get into mobile robots, the initial project can grow and grow (which I feel is part of the fun).
There are international robot competitions which require relatively simple mechanics to get started, e.g. in the UK http://www.tic.ac.uk/micromouse/toh.asp
Ultimate performance require specially built machines (for lightness) , but folks would get creditable results with an Arduino Nano, the right electronics, and a couple of good motors.
A line following robot is the classic mobile robot project. The track can be as simple as electrical tape. Pololu have some fun videos about their near-Arduino 3PI robot. The sensors are about £1, and there are a bunch of simple motor+gearbox kits from lots of places for under £10. Add a few £ for motor control, and you have autonomous robot mechanics, in need of programming! Add an Infrared Remote receiver (about £1), and you can drive it around using your TV remote. Add a small solar cell, use an Arduino analogue input to measure voltage, and it can find the sun. With a bit more electronics, it can 'feed' itself. And so it gets more sophisticated. Each step might be no more than a few hours to a few days effort, and you'll find new problems to solve and learn from.
IMHO, the most interesting (low-cost) competitions are maze solving robots. The international competition rule require the robot to explore a walled maze, usually using Infrared sensors, and calculate their optimal route. The challenges include keeping track of current position to near-millimeter accuracy, dealing with real world's unpredictably noisy environment and optimising straight-line speed with shortest distance cornering.
All that in 16K of program, and 1K RAM, with real-time interrupt handling (as much as 100K interrupts/second for some motor systems), sensor sampling, motor speed control, and maze solving is an interesting programming challenge. (You might make it 'easy' with 32K of program, and 2K RAM :-)
I'm working on a 'constrained' robot challenge (based on Arduino) so that robot performance is mainly about programming rather than having a big budget.
Start small and build up to something more complex. Control servos. Blink LEDs. Debounce inputs. Read analog sensors. Display text on an LCD. Then put it together.
Despite the name, I like the "Evil Genius" book for PIC microcontrollers because of the small, easily digestible projects that tend to build on one another. It is, of course, aimed at PIC programmers rather than the Arduino, but the material covered will be useful no matter what you're developing on.
I know Arduino is trendy right now, but I also like the Teensy++ development board because of its low price-point ($24), breadboard-compatible PCB, relatively high pin count, Linux development environment, USB connectivity, and not needing a programmer. Worth considering for smaller projects.
If you come up with something cool, let me know. I need an excuse to do something fun :)
Bicycle-related ideas:
theft alarm (perhaps with radio link to a base station which is connected to a PC by Ethernet)
fancy trip computer (with reed switch or opto sensor on wheel)
integrate with a GPS telematics unit (trip logging) with Ethernet/USB download of logged data to PC. Also has an interesting PC programming component--integrate with Google Maps.
Other ideas:
Clock with automatic time sync from:
GPS receiver
FM radio signal with embedded RDS data with CT code
Digital radio (DAB+)
Mobile phone tower (would it require a subscription and SIM card for this receive-only operation?)
NTP server via:
Ethernet
WiFi
ZigBee (with a ZigBee coordinator that gets its time from e.g. Ethernet or GPS)
Mains electricity smart meter via ZigBee (I'm interested now that smart meters are being introduced in Victoria, Australia; not sure if the smart meters broadcast the time info though, and whether it requires authentication)
Metronome
Instrument tuner
This reverse-geocache puzzle box was an awesome Arduino project. You could take this to the next step, e.g. have a reverse-geocache box that gives out a clue only at a specific location, and then using physical clues found at that location coupled with the next clue from the box, determine where to go for the next step.
You could do one of the firefighting robot competitions. We built a robot in university for my bachelor's final project, but didn't have time to enter the competition. Plus the robot needed some polish anyway... :)
Video here.
Mind you, this was done with a Motorola HC12 and a C compiler, and most components outside the microcontroller board were made from scratch, so it took longer than it should. Should be much easier with prefab components.
Path finding/obstacle navigation is typically a good project to start with. If you want something practical, take a look at how iRobot vacuums the floor and come up with a better scheme.
Depends on your background and if you want practical or cool. On the practical side, a remote control could be a simple starting point. It's got buttons and lights but isn't too demanding.
For a cool project maybe a Simon-style memory game or anything with lights & noises (thinking theremin-style).
I don't have suggestions or perhaps something like a line follower robot. I could help you with some links for inspiration
