Itä-Suomen yliopistossa Joensuun kampuksella sijaitseva Sm4rtLab tuo laajennetun todellisuuden mukaan fotoniikan opintoihin. Maailmassa täysin ainutlaatuinen projekti on toteutettu yliopiston fysiikan ja matematiikan laitoksen, Tietotekniikkapalveluiden ja Suomen Yliopistokiinteistöjen voimin. Tietotekniikkapalveluiden opetusteknologia tiimi vastasi tilan AV-suunnittelusta, -laitehankinnoista ja -asennuksesta käyttöön ja tässä pieni esittely tilan AV-toteutuksesta.
AV-tekniikka integroituu laboratoriossa niin että se mahdollistaa laboratorion käyttämisen paikallisesti tai etänä mistä tahansa päin maailmaan. Oikeaa optiikan laboratoriota voidaan ohjailla myös etänä omalta tietokoneelta käsin ja toinen vaihtoehto on käyttää Microsoftin HoloLenseja, eli laajennetun todellisuuden laseja.
Salin kameratekniikasta vastaa nurkkiin sijoitettut Axis V5915 PTZ kamerat (katso 360 kuvaa) joista kuva siirtyy käyttöliittymään IP-kautta. Laboratorion yläkameraksi valikoitu erittäin laajakulmainen AXIS M3046V verkkokamera. Kuva saadaan kameroista myös ulos HDMI -> HDBaseT kaapeloinnin ja Kramer TP-580R + TP-580T muunniparin avustuksella Kramerin VS-62H 6x2 HDMI matriisiin, joka sijaitsee Sm4rtlabin etutilassa. Kuva voidaan ohjata myös suoraan Skype For Business lähetykseen Magewell HDMI USB 3.0 Capture Donglen (Tämä tuote oli UEFin löytö ja kumppanimme AV-Marketing ansiosta tuotteella on nyt maahantuoja - SUOSITTELEN) kautta ja kameraa voidaan vaihtaa lennossa matriisin kautta Skype4B yhteyteen (kuvan vaihtoviive -1sek)
Etutilan huomion vie iso CTOUCH 65inch Laser air+ 32p kosketusnäyttö, jonka kautta myös Sm4rtLabin käyttöliittymän hallinnointi ja käyttö onnistuu. Skype4B lähetystä varten käytössä on langaton AKG WMS45 Sport Setti ja pieni USB äänimikseri, josta äänet siirtyy kätevästi tietokoneelle.
Fotoniikan professori Pasi Vahimaa Fysiikan ja matematiikan laitokselta, esittelee video välityksellä livenä labrasta käsin Sm4rtLabin toimintaa Tutkimuksen IT-seminaariin Kuopioon, yliopiston LifesizeCould palvelun kautta.
Osa Joensuun kampuksen Metria-rakennusta on vielä peruskorjausremontin alla. Sm4rtLab laajenee remontin valmistuttua myös Metrian pääaluaan, jonne on vedetty HDbaseT kaapelointi info-näyttö varten. Tätä kautta voidaan heittää kuvaa labrasta Kramerin matriisin kautta, mistä tahansa kuvakulmasta ja näin avata labran toimintaa myös alan yleisölle.

Yo-kokeet sähköistyvät ja tämä tuo uusia mahdollisuukisa kokeen toteuttamiseen monella eri saralla. Kielissä suurimpia kehittelyssä olevia uudistuksia on tietokone avusteinen suullisen kielitaitojen mittaaminen.
Digitala-Hanke on kehittämässä juuri tämänkaltaista systeemiä. DigiTalasta vieraanamme oli kieltenopettajille suunnatussa workshopissa Erik Lindroos, Heini Kallio ja Aku Rouhe, jotka syväluotasivat puheenarviointiin liittyviä uudistuksia. Workshop järjestettiin Riihimäen lukiolla, joka on ollut jo aiemmin mukana DigiTalan tutkimuksen pilottikokeissa. Kielten opettajat olivat varovaisen myönteisiä uudistuksille ja hanke herätti paljon kiinnostusta ja pohdintaa tulevaisuuden tuulista.
There are some people who still think that sending or sharing files to other instantly is quite troublesome. Well, they are definitely wrong because developers have created some amazing apps for file-sharing these recent years, and each of these mobile apps is so amazing that you’ll get confused as which one to choose.
Today's Internet allows an array of mediums for sharing files across different platforms. However, sharing large files still…Read more
After trying lots of them, I’ve concluded some best file-sharing platforms which you should have in your phone. Of course, I rated these apps based on the ease of usage as well as some pros and cons that come with them. So, let’s dig into the list to know more about these apps.
WeTransfer has become one of the leading file-sharing mobile apps to date. One of the main reasons why you should use this app is due to the simplicity of its file sharing/sending procedure. Yes, as soon as you get to the official site, you can start sending files to your friends without even registering.
However, remember that the file you send will be available for a week. Also, there is a 20gb file size limitation per transfer, which is actually quite enough. But if you need more expiration time and sending file capacity, you can purchase the plus version which lets you choose your own expiration time for the file you send. The file limitation? Unlimited!
As for the receiver, they will get an email notification which will direct them to the main site to get the file. Yes, as easy as that. It is available for Android, as well as iOS phones. WeTransfer is also ‘kind’ on your phone because the size of the app is small, and it doesn’t even take much RAM when you are using it.
Easy to use, no need to register
Also very easy for the receiver to download the file
Big size limitation (even for the free user)
The size of mobile app is small
Attractive background and sound during downloading and uploading
There is a time expiration (7 days) for the free users before the file can be downloaded by the receiver.
Pibox is one of the most unique file-sending platforms out there. Aside from the ability to share or send files, this app lets you chat with your friends in a messenger-like mode. So, if you are a great fan of chatting, you will definitely love Pibox.
However, you have to register first before you can start sending files or chatting with your friends. Also, you have to invite your friends using their phone numbers to start chatting and sharing files.
Anyway, after registering, you will be given a free 3 GB storage to use. You can keep increasing the storage up to 1000 GB by inviting your friends to register in Pibox. So far, there is no paid version for Pibox, so every user is treated the same here. Pibox is currently available for Android and desktop. The developers of the app say that the iOS version will be developed soon.
No quality loss upon sharing files between users
3 GB free cloud storage after registering for the first time. You can increase it up to 1000 GB by inviting your friends to join Pibox
You can chat with your friends in a private or group chatroom
Fast uploading speed
The app is free for everybody, means that everybody gets the same services
You can change your profile picture as you prefer
No browser bookmarklet available yet
You can only invite your friends via their phone number
Currently, Pibox is only available for Android users
Filemail is quite similar to WeTransfer in term of sharing/sending simplicity. You can stay as a free user if you want, and don’t even need to register to start sending files to your friends.
However, unlike WeTransfer, Filemail offers 30 GB size limitation for file sending. The receiver has 7 days time limit to download the file you send before it’s gone forever. However, the pro and business version lets you send unlimited file size as well as controlling the time expiration for the file you send.
Filemail also has other awesome extensions to use for free, i.e., Filemail downloader and receiver (to increase download speed) and Filemail API (for developers). This app is available for Desktop, Mac, Android, iOS and Linux.
Very easy to use for both the sender and receiver
No registration needed (if you are a free user)
The files shared maintain their original quality
30 GB size limit to send files if you are a free user, and it’s unlimited if you buy the pro/business version
Supports almost any major platforms, such as Android, iOS, Mac, Windows and even Linux
Fast-response and helpful customer service
There is free Filemail Downloader and Receiver extension to make your uploading or downloading process faster
Filemail API is also available for developers
The uploading speed is rather slow compared to the other file-sharing program
There is a bug that says ‘no mobile data allowed, rescheduling transfer’ before you send files via mobile app. Filemail team hasn’t done anything to fix the bug or even answered the complaints from mobile users
Upon uploading, if you close the page, means your process will be lost and you have to start over
There is a 7 days time expiration for the free user
Send Anywhere takes an easy, quick, and unlimited approach to file sharing. And after trying it myself, I guess it is not an exaggerated statement. You can actually send any files easily to others in really simple steps. There is one important point which you have to underline about Send Anywhere, which is the 6 digits code system.
So, if you want to try the app without registering, you simply have to go to the official site and upload the files you want to send. After that, you will receive 6 digits code. If the receiver has Send Anywhere installed in their phone or computer, then they should insert the code to download the files you sent earlier. Otherwise, you simply need to give them the link to download page.
Most sending/transferring files programs ask you to provide the email or phone number of the receiver, but with Send Anywhere, you don’t have to, and that is the strongest point of this program.
Another good thing is that you can upload or receive as many files as you want, and there is no paid or pro version, so everyone gets the same service. However, the receiver has to wait 60 seconds before downloading the file.
You don’t have to insert your email or phone number of the receiver
Privacy both sender and receiver is secure
The service is totally free. There’s no paid or pro version
When you send download code to receiver, they need to wait for 60 seconds before able to download the file
Volafile.io is a live filesharing and chat service that strongly believe in protecting the anonymity of the users. Simply put, this program doesn’t ask your or the receiver’s email, phone number and any other confidential data. You don’t even need to register to use Violafile.
Apart from that, this program is totally easy to use. As soon as you get to the site, you can create a ‘room’ (like a chat room) and share the room’s link to the receiver to chat while uploading the files.
People like this program because it protects your privacy and is simple to use. Not to mention that you can send as many files as you want. Oh, and you can invite more than one people to the room. The only problem is that Violafile has no mobile app, so the user has to access the room via browser (from desktop or mobile). And the other thing is, the file you uploaded to to this app will only last for about 2 days before it is taken down.
It is like a social media for big file sharing. So you could put files into group room and share with anyone you want.
There’s not only the option to send big file but you can make motion picture too from photos you uploaded in Violafile
Violafile doesn’t have mobile app version, so you can only use it in mobile or desktop browser.
Pcloud offers free service to send your big files up to 5GB instantly. Its simple interface allows you to upload multiple files through drag and drop. Then fills the receiver email form where you can add up to 10 of your friends to receive your files. After that, you need to fill in your email address (as sender) and an optional message. Your files will be delivered in one click with ‘send files’ button.
The great features that the company offers is, you can encrypt your files to achieve data security. No one can access your files until they see the password.
Can deliver your files up to 5gb instantly
Encrypts your files for data security
No mobile/desktop app provided
Sending or sharing things has turned into such a lifestyle across the cyber world now. We used to send files to others using e-mail, which is convenient, but there is a size limitation which makes things not fun anymore.
The mobile apps and online services mentioned above, are one of the best available in the market that take the hassle out of file sharing and let you enjoy the different features that they offer. Let us know about your experience with any of this app or service.

Whether from Stephen Hawking, Siri, or anyone in between, we’ve all heard quite a lot of electronically synthesized speech by now. But less than eighty years ago, the very idea of a human-sounding voice produced in a mechanical manner inspired wonder and disturbance in equal measure. The everyman and everywoman got their first chance to hear such a technology at the 1939 New York World’s Fair, during its hourly demonstrations of the very first speech synthesizer, the “Voder.” Who, they must have imagined as they stood before its booming square-jawed-Art-Deco-hero logo, could have invented such a thing?
Homer Dudley, an electronic and acoustic engineer at Bell Labs, had in the 1920s invented the “Vocoder” (or “Voice Operated reCorDER”), a device that could convert human speech into an electronic signal and then, somewhere else down the like, turn that signal back into speech again.
For the Voder (or “Voice Operation DEmonstratoR”) he took the initial voice out of the signal, creating a kind of synthesizer dedicated to the sounds of speech that one could operate manually, through an interface somewhat resembling that of an organ. Its controls (which you can see diagrammed at 120 Years of Electonic Music) presented a steep enough learning curve that fewer than thirty people, mostly the “girls” employed for the Voder’s demonstrations, ever learned to play it.
Though impressive for the time (the other feat of artificial humanity at that World’s Fair being Electro the Smoking Robot), “the Voder’s speech came out a little hard to understand, and even a bit unsettling,” according to Atlas Obscura. “The Voder was shown again during San Francisco’s Golden Gate International Exposition in late 1939, but after that, the machine disappeared almost instantly.” Speech synthesis itself, by contrast, had come to stay, though progress would remain relatively slow for the next four or five decades. Now, in the 21st century, it exists all around us, and despite considerable improvements in realism, its voices still retain a bit of the unearthly awkwardness of the Voder — and we probably wouldn’t have it any other way.
Jeanne C. Meister describes three new roles that have emerged as corporate e-learning departments adapt to changes in the learning landscape. The roles are:
Curators: "learning leaders increasingly focus on facilitating and orchestrating learning aligned to their organization’ s growth priorities."
Design thinking: "a human-centered, prototype-driven process for innovation that can be applied to product, service and business design."
People analyst: "uses machine learning to calculate the relative importance of geography, compensation, employee and manager engagement at the aggregate level."
I don't like any of the titles. They're each different types of research, not simply the function-driven positions that the titles imply. Maybe they should be called scholar, designer and demographer, respectively.
