OoVoo

OoVoo is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand OoVoo rather than just read about it. In short: ooVoo was a video chat and messaging app developed by ooVoo LLC and owned by Krush Technologies, LLC. ooVoo had applications for Android, iOS, Mac OS X, Microsoft Windows, Windows Phone, and Facebook. The original Microsoft Windows app was released in 2007.

Key takeaways

OoVoo belongs to computer science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect OoVoo to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of OoVoo from memory before moving on to harder problems.

Reference excerpt

ooVoo was a video chat and messaging app developed by ooVoo LLC and owned by Krush Technologies, LLC. ooVoo had applications for Android, iOS, Mac OS X, Microsoft Windows, Windows Phone, and Facebook. The original Microsoft Windows app was released in 2007. It was discontinued on November 25, 2017.

Features ooVoo allowed users to communicate through free messaging, voice, and video chat. ooVoo video conferencing technology can have HD video and audio calls with up to twelve participants simultaneously and desktop sharing.

History ooVoo was founded in 2006 by Philippe Schwartz and Ohio entrepreneur Clay Mathile based on technology developed at Arel Communications and Software (formerly NASDAQ:ARLCF). Arel was founded in 1982 and specializes in remote e-learning collaboration application software. On March 13, 2006, Arel Communications was taken private by its current owners and relaunched as ooVoo. In June 2007, ooVoo for Microsoft Windows launched, with a video chat feature. In February 2008, video call recording and phone calling were introduced. In May 2008, ooVoo for Apple's OS X launched, creating cross-platform capabilities for video chat. In February 2009, ooVoo 2.0 launched and featured browser-based video chat rooms and video chat through a web link with no download required. An open API was launched with version 2.0, allowing developers to build customized applications and widgets. In May 2009, ooVoo introduced the first air-to-ground three-way video conversation. ooVoo version 2.2 was launched in July 2009, and introduced business plans geared for multiple seats and desktop sharing. New pay-as-you-go options and international phone calling were also introduced. In January 2010, ooVoo released its app for Android mobile devices. On 2 June 2011, ooVoo launched its social video chat service on Apple's iPhone (and other iOS devices), making its free HD Video chat service cross platforms, including: PC, Mac, Android and iPhone. On July 22, 2013, ooVoo released a Software Development Kit (SDK), allowing other applications to leverage its video chat technology (current apps leveraging the ooVoo SDK: Flinch, Heystax). On June 10, 2014, ooVoo released its app for Windows Phone devices. On September 9, 2014, ooVoo released its Video SDK for WebRTC. On November 25, 2017, ooVoo announced via Twitter that it would be shutting down, citing a lack of profit as the reason.

Accolades ooVoo won PC Magazine's Software Innovation "Best in Show" Award at the DigitalLife Expo in September 2007. In March 2008, ooVoo won the "Webware 100" award for Communication. ooVoo won PC Magazine's Best Mobile Product of 2011 in the Android Category ooVoo won the Tabby Award in the Social category for its Android app in August 2013. ooVoo was a nominee and finalist for a Mobby Award in the Business Collaboration category for its Android app in September 2015. ooVoo was honored in 2016 with a Mobile Excellence Award for Best Social Community. ooVoo won the CES Innovation Award Honoree in 2016.

Worked examples

Example 1 — a first encounter with OoVoo

Start with the simplest possible case. Write down what OoVoo claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to OoVoo before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about OoVoo ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of OoVoo

In research: OoVoo appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses OoVoo in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: OoVoo is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2007 software, Defunct instant messaging clients, MacOS instant messaging clients, so understanding it makes those chapters shorter.
In everyday life: Look for OoVoo outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
