Features of project Valkyrie:
Glove: Project Valkyrie is aimed to complete the challenge "SpaceGlove". For the 2 days that we have worked on that project we have made a glove from leather and elastic material that is comfortable for everyday use and works about 70 hours on full power transmitting mode.
With that glove, we made experiments to control many of the standard home devices (light bulbs, lights, fan heater, LED light strip, TV, setup box) with based gestures such as slide, up-down, down-up etc. After that we made a service that is transmitting data from the glove to an iPhone, and we have modified the gesture data base, and added custom gestures. With 10% precision we have successfully distinguished 16 different gestures and added support for more than 60.
For controlling many interfaces we need a control center that is repeating signals received from any of the communication interfaces and sending it to the other interfaces.
The following interfaces are supported:
Glove sensor positions and descriptions:
Mobile applications: We have developed 2 applications for interfacing with the command center (and the glove) - one for Android and one for iOS. The Android application uses only the voice detection service using the google now search and if command is recognized it sends http post request to our online service (electric imp). The Android service is working on phone as well as on Android watch. The iOS application supports custom made Voice recognition service, home automation control using voice or direct input in the application, and weather station information. Our wellness service is checking your heart rate automatically every 30 minutes or continuously while you are training. It can also count your steps and detect your sleep quality. The application can also be used for uploading new firmware to the glove and to create more gestures to be recognized by the glove and bind them to execute a variety of actions.
At the moment, we have a fully functional glove, iOS application with all the properties that we need, remote controls for computer (glove acting like HID device), phone control though BLE HID service, smart home control with custom and already implemented gestures, robo arm control, computer game control, rover/car gesture control, Smart TV remote control and many more because of the universal V-API protocol which can be used in many places.
There is no gravity in the open space - we can use a magnetic transmitter to determine the 'zero' point in the space and use it to calibrate and sense pseudo gravity and angle velocity.
It is hard to use most of the GHz communication devices in the space - This is why we have 433 MHz transceiver on the Control Center. The VHF and UHF bands are able to penetrate the earth atmosphere and transmit low noise communication from the earth to space. This is used by the Radio amateurs to make QSOs using the International space stations as repeater.
Low data speed if the controlled device is far away from earth - there is not much that we can do about that, so we decided to make custom macros(for example if you are controlling robotic arm), you make the movement once with you hand then this is send to the robotic arm, it memorizes the movement and do it by command. For example on the video we have used this system to grab the box and move it few inches behind.
Connection drops while controlling something - If there is no connection for 300 ms, the operation stops until the connection is not resumed.
Charging - we are considering wireless charging, because with the new technologies in the wireless charging it is possible to charge 800 mAh battery for less than 40 min.
Power consumption - it is 13 - 15 mA in transmitting mode.
Can you use external devices (such as android phones, bluetooth joystic) for controlling Control Center Peripheral devices - Yes you can V-API is universal protocol for communication, all of the received reports are repeated to the other communication interfaces.
