Reference excerpt

The Kobo Aura HD (also called the Aura HD) is a limited-edition Kobo eReader device designed and marketed by Kobo Inc. It was revealed 15 April 2013 and allowed for preorders the next day at a price of 169.99 USD/CAD. It arrived in stores in Canada and the United Kingdom on 25 April 2013. The marketing slogan of the Kobo Aura HD was "The eReader, reimagined." In October 2014 the Kobo Aura H2O was launched, it has a similar screen resolution to the Kobo Aura HD but has a waterproof coating. Kobo's CEO announced in March 2015 that the Kobo Aura HD was officially discontinued.

Hardware The hallmark feature of this device was the display – at 6.8 inches (diagonal) it was larger than other popular e-book readers such as the Kobo Glo, Kindle Paperwhite, and Nook Simple Touch with Glowlight with screens of 6 inches. The screen offered by the Aura HD offered 30% more screen area than the 6-inch screens of competitors. It was also of a much higher resolution, with a WXGA+ 1440 × 1080 screen offering 265 ppi; with Pearl E ink technology, the screen allowed for a much improved text rendering. This screen was marketed as the "ClarityScreen+" by Kobo. The Aura HD shipped in three colours: espresso, ivory, and onyx. It was made of a new material; whereas previous Kobo eReaders used a soft touch matte plastic, the Aura HD's body was made of a harder, shinier, plastic. This was accompanied with an angular back design, resembling crumpled pages of a physical book, used for added grip. The CPU is 1 GHz Freescale i.MX507. Built-in memory totalled 4 GB, allowing 3,000 books to be stored on the device. This was expandable via microSD card slot; adding up to 32 GB of storage was possible. The ComfortLight introduced in the Kobo Glo was also present in the Kobo Aura, allowing a user to read in the dark. Battery life was estimated to be up to two months, assuming 30 minutes of reading a day and Wi-Fi turned off.

Software Kobo Aura HD runs on the Kobo Firmware, based on the Linux kernel. The software is available in eight languages and two variants: English, French, Canadian French, Japanese, German, Dutch, Italian, Spanish, Portuguese, and Brazilian Portuguese. The operating system was redesigned with the launch of the Aura HD, featuring a new library view and a new home screen. The main application, the digital reader, supports a variety of ebook formats: ePub, PDF, Adobe DRM, RTF, HTML, TXT, Comic Book Archive file, JPEG, PNG, BMP, GIF, and TIFF. By flicking or tapping a side of the screen, the user may advance to the next page or previous page. Finetuning a font in a book is possible with a feature called TypeGenius: users can change the weight, sharpness, and font size of any preinstalled fonts on the Kobo. Highlighting, adding notes, and looking up definitions in the built-in dictionaries is also possible by long-tapping a passage in any part of the book. The Kobo Aura HD also provides statistics about reading progress: average reading time per session, total time read, pages turned, and the percentage of books completed. Users may also download books through the use of the Kobo Bookstore. Adding books to a wishlist, purchasing books, and browsing through the library can be done on the Kobo itself thanks to the Wi-Fi chip. Once purchased, books are saved in the cloud and can be redownloaded at any time if the user has deleted the book from his/her device. This feature also allows for reading location, bookmarks, highlights, and notes to be synced across many devices.

Reception The reception of the Kobo Aura HD was generally positive. Reviewers appreciated the larger screen, the increased pixel density, the ComfortLight, and the abundant storage options. The pricing was the universal gripe: although many felt that the eReader was worth it, they noted that it cost $30 more than the closest competitors. In 2013 it contributed 25% of all of Kobo's hardware sales.

Worked examples

Example 1 — a first encounter with Kobo Aura HD

Start with the simplest possible case. Write down what Kobo Aura HD claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In 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 Kobo Aura HD 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 Kobo Aura HD 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 Kobo Aura HD

In research: Kobo Aura HD appears in 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 Kobo Aura HD 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: Kobo Aura HD is common in secondary-school and first-year university syllabi. It links to neighbouring topics Dedicated ebook devices, Kobo Inc., Linux-based devices, so understanding it makes those chapters shorter.
In everyday life: Look for Kobo Aura HD 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.
