Chapter 7 Tagging Objects with the Nokia Point & Find Client Application

Lighting Conditions

If an object is always in the same lighting (such as an indoor object under constantly controlled lighting), taking three to five tags of the object will suffice.

If an object is found under dif- ferent lighting conditions (day, night, bright, cloudy, supple- mental lights on or off, etc.), then take three to five tags of the object under each (or most) lighting conditions.

Multiple Tagging

When tagging a movie poster, for example, Nokia will take five tags of a poster from differ- ent angles and distances, under one to three different lighting conditions for a total of approx. five to 15 tags. When tagging a storefront, Nokia will take five to 10 tags from different angles at a distance of approx. six feet and 12 feet from the store for a total of 10 to 20 tags.

Helpful pointers for tagging

Tag an object multiple times from a few different angles and dis- tances – and under different lighting conditions when appropriate

– in order to improve recognition success of your targets (objects). Depending on the object, three to five tags per environmental condi- tion – day/night, indoor/outdoor lighting – is sufficient.

Include tags with a focus on any logo names or fixed images that are on (or part of) an object, and also include tags with a focus on the entire object.

Do not focus on small text or areas within the target that may change over time (as in a window display that will change in a store front).

In summary:

•Tag objects from multiple angles

(approximately 30 degrees each side of center).

•Tag objects from the front and back, close up, and from a distance.

•Tag objects under several lighting conditions (day, night, bright, cloudy, artificial lights, etc.)

•Include tags for logos or fixed images that are part of, or on, an object

•Do not tag small text areas or images that will change over time

Nseries specifications

The Nokia Nseries, launched in the mid-2000s, represented a groundbreaking line of multimedia smartphones that combined innovative technology with sleek designs. This series reinvigorated Nokia’s reputation as a leader in mobile phone technology while catering to a new generation of tech-savvy users looking for powerful devices that could handle various multimedia tasks.

One of the standout features of the Nokia Nseries was its commitment to high-quality multimedia capabilities. Equipped with advanced cameras, many models boasted Carl Zeiss optics, allowing users to capture stunning photos and videos. The Nokia N95, for instance, featured a 5-megapixel camera that set a new standard for mobile photography. In addition, the Nseries often included dedicated multimedia buttons, making it easier for users to access their favorite media apps and functions.

Displaying vibrant colors and impressive clarity, the Nseries devices typically used high-resolution screens. These displays not only enhanced the multimedia experience but also made browsing the internet, reading e-books, and enjoying games visually engaging. The inclusion of features like a built-in music player supported a rich audio experience, with many models offering support for various audio formats.

Connectivity was another hallmark of the Nseries. Users could expect 3G capabilities, Wi-Fi, and Bluetooth support, allowing seamless sharing and downloading of content. The devices also usually incorporated GPS functionality, a feature that became increasingly important for navigation and location-based services, marking the Nseries as a pioneer in integrating location technology into mobile phones.

Software-wise, Nokia Nseries phones ran on the Symbian operating system. While not as user-friendly as later platforms, Symbian provided users with a level of customization and extensive app availability through the Nokia Software Market. This allowed users to personalize their devices according to their preferences, maximizing their utility.

The Nokia Nseries encapsulated a perfect balance of form and function. The sleek designs and premium materials reflected Nokia’s commitment to quality, while the powerful features emphasized the trend towards multimedia smartphones. By combining photography, video, music, and internet capabilities, the Nseries paved the way for today's smartphones, influencing how devices are designed and utilized in modern life. Though the series has been discontinued, its legacy remains visible in the evolution of mobile technology.
