“Natural interaction on computer games is a common problem faced by game designers. For that reason, it is necessary to explore new interaction paradigms like tracking technologies in order to provide novel techniques for interacting with video games. For instance a head tracking system can be used to make the body movement tangible on the virtual world of the game.
The objective of this paper is to provide a technological solution to the creation of a low-cost head-tracking's solution, using the infrared light detection through the Nintendo Wii Remote.”

“The sedentary lifestyle is a common problem in most countries, such as Mexico. For that reason, it's necessary to promote a lifestyle change that includes physical activities and a healthy nutrition. The objective of this paper is to provide a technological solution to motivate people to walk, receive health benefits, and additionally, receive points, which can be exchanged for prizes. With this we pretend to motivate people to walk and improve their health. Thus, if a person doesn’t walk to improve their health, we will encourage it with a prize.”

“The problem of providing appropriate and effective medical care to the elderly has gained importance in recent years because of the exponential growth of people older than 65 years. This research work proposes using interactive television embedded in a ubiquitous computing environment to help mitigate some of the effects of discrimination and provide health services to older adults living alone in their homes who require timely medical attention.”

“As in many Latin–American countries, in Mexico many older adults live alone as a result of the migration of one or more of their relatives, mostly to the USA. Thus, not only do they live alone, but they might seldom see these relatives for long periods, even though they often depend on them financially. With the goal of designing appropriate communication technology for seniors and their relatives experiencing this situation, we conducted interviews and evaluated scenarios and prototypes to reveal the practical ways they maintain emotional ties despite the distance. Based on those findings, we envisioned a communication system through which seniors and their relatives can maintain close social ties by sharing information, personal reminiscences and stories. We found that older adults perceived the system as a richer, natural form of communication with their relatives that could facilitate their integration into the networks that currently connect members of their families.”

“A user-centered design approach based on ethnographic interviews and prototype evaluations, our research group envisioned a home-based pervasive communication system. The Electronic Family Newspaper (EFN) facilitates communication between elders and their families living abroad. The system is a blogging tool that operates on a tablet PC. Family members can access the system through any Web browser. The EFN lets users share messages, attach pictures, and create news sections, and elders can play the included memory game (based on revealing pairs of pictures).”

“The aging of the population is a phenomenon faced by most nations, such as Mexico, where 7.5% of the population is older than 60 years, a significant proportion of whom live alone (10%). This fact is related with the ever increasing migration of one or more of their relatives, mostly to the USA. Our work aims to provide a technological solution that eases the isolation of elder people living alone in Mexico while their families are abroad. To envision and inform our design we interviewed independent old persons living alone. We propose an electronic family newspaper, through which elders and their families share information, personal reminiscences and cultural stories, and occasionally interact with each other. Through its functionality, the electronic newspaper enables elders not only to maintain close social ties, but ameliorate cognitive decline.”

In: Sixth Mexican International Conference on Computer Science Sep 26-30, 2005, Puebla, Mexico. pp. 18-25.
“The aging of the population is a phenomenon faced by most nations. Growing old is often accompanied of a loss of close companionship which has been shown may aggravate the cognitive impairment of elders. From a qualitative study, key issues emerged regarding unmet needs of elders communication that we propose to address with Web-based technology. We decided to create an electronic family newspaper to incorporate elders to the current social networks created by their younger relatives who already communicate through Internet applications, such as IM and e-mail. The system uses Web-based technology to make it accessible from any Web browser for those users living abroad. To serve the needs of elders and make the input of information easier, several autonomous agents help the user to interact with the system that can be accessed by any electronic display with a touch screen, such as a tablet PC.”

Knowledge wants to be free !
We have decided to give away world-class educational materials
because we believe that universal access to high quality education is key to the building
of peace, sustainable social and economic development, and intercultural dialogue.
To calculate just have much we have saved you, our wonderful readers, we compare our free encyclopedia to two
books we love:
$110: Human-Computer Interaction by Dix et al (a great textbook but without video interviews)
$116: Shneiderman's Designing the User Interface
(a great textbook but without video interviews).
As you are reading our encyclopedia on your iPad/tablet (and saving a few trees), we estimate that the price would be $90 if sold as an eBook.
With that number, we can calculate how much money we have saved our readers, based on calculating the number of readers.
How we calculate readership
Because of our online and tablet/iPad approach to publishing, we are able to precisely measure reading behaviour across hundreds of parameters in realtime: Anything from reading
speed, drop-off points in the text, reader demographics, and much more.
Based on our server logs and the Google Analytics API,
we calculate the number of readers as described in the calculation method below.
A reader is not the same as a simple pageview and a reader is not the same as a
website visitor (as described in our calculation method below).
We calculate readership for two types of readers:
- Readers that have read our whole encyclopedia, much the same way you read a printed book
- Readers that have reader an individual chapter
Calcalution method: How we define a reader
- First we use the Google Analytics API to get a report of the number of unique human visitors to a chapter/page. Google runs its business on ads and thus completely relies on the ability to distinguish between a human visitor and an automated request. If not, you could earn millions on automating clicks on Google Ads.
- We then compare that number to our Apache webserver logs, which report the much higher number of actual visits to a chapter/page (both human and automated). We calculate the difference in percent, which we call an "exaggeration factor", which we use in step 6 below.
- With a large part of the visitors excluded, we further exclude any visitor who:
- has not remained on the page for at least 3 minutes (this factor is calculated by recording visit durations of 1000 randomly selected visitors) or has not printed the page (i.e. has not visited the printerfriendly version of the chapter/page)
- has not scrolled the page (this factor is calculated by recording scroll movements on 1000 randomly selected visitors)
- We then further exclude "double readers", i.e. readers who read a portion of a chapter and then returns in,
say, a week or a month to read the rest.
Although this person's reading activity spans multiple server sessions, the person is only counted as a single reader.
We categorize a "double reader" as a visitor who:
- visits a page, or multiple pages, across multiple server sessions
- qualifies to be defined as a reader, cf step 1-3 above, in all server sessions
- uses the same originating IP address
- We then subtract 5% from the final number to counter-balance a last remaining factor, namely the situation where one reader reads a chapter on his/her tablet
using a WiFi connection (and counted as one reader) but then picks up his other tablet using a 3G dongle
(with another IP address) and re-reads some of the chapter. That will equal two readers, not one. We have no way
of calculating how many times this situation arises, but to be on the safe side we subtract 5%
from the final number.
- We then take half of the "exaggeration factor" from step 2 and substract from the final number. We do this for no rational reason. We do it only as a further measure to be certain that our number of readers is not inflated.
- To qualify as a reader who has read our whole encyclopedia - much the same way you read a printed book - that person must have qualified as a reader (cf. 1-6 above) of at least 80% of the encyclopedia chapters.
As a result, we have eliminated everything from automated requests to the more casual visitors. That leaves us with what we can safely call readers.
