Multitasking Behaviour and Gaze-Following Technology for Workplace Video-Conferencing.

[This post was written by Eveline van Everdingen and describes her M.Sc. project]

Working with multiple monitors is very common at the workplace nowadays. A second monitor can increase work efficiency, structure and a better overview in a job. Even in business video-conferencing, dual monitors are used. Although the purpose of dual monitor use might be clear to the multitasker, this behaviour is not always perceived as positive by their video-conferencing partners.

Results show that multitasking on a dual screen or mobile device is indicated as less polite and acceptable than doing something else on the same screen. Although the multitasker might be involved with the meeting, he or she seems less engaged with the meeting, resulting in negative perceptions.

Effect of technology on politeness of multitasking

Improving the sense of eye-contact might result in a better video-conferencing experience with the multitasker, therefore a gaze-following tool with two webcams is designed (code available at https://github.com/een450/MasterProject ). When the multitasker switches to the dual screen, another webcam will catch the frontal view of the multitasker. Indeed, participants indicate the multitasking behaviour as being more polite and acceptable with the dynamic view of the multitasker. The sense of eye-contact is not significantly more positive rated with this experimental design.

These results show that gaze-following webcam technology can be successful to improve collaboration in dual-monitor multitasking.

A Sugar Activity for Subsistence Farmers

[reblogged from http://worldwidesemanticweb.org/2015/03/06/a-sugar-activity-for-subsistence-farmers/ This post is written by Tom Jansen]

Subsistence farming or agriculture is a form of farming where farmers mainly focus on growing enough food to be self-sufficient. Especially in African countries, where people are very dependent of own-grown food, this type of farming is very common. Subsistence farming, however, in these countries has so much to gain and has so much potential. Improving the farming skills of the farmers could make significant contributions to the reduction of hunger. Unfortunately, farmers often haven’t had enough agricultural education to optimally grow their own food. To help these farmers, I developed an activity that will improve their farming skills. The application helps the farmers to identify diseases of their crops and animals and will present them ways to manage the diseases and prevent them in the future. Giving them an opportunity to manage diseases of their crops and livestock means giving them an opportunity to improve their harvest. The opportunity of a bigger harvest could be a substantial contribution to a better way of living for farmers in (a.o) West Africa.

The activity is Sugar based and is therefore perfectly suitable for the XO-Laptops that are commonly used in West Africa. The activity revolves around a database with a lot of information about diseases of crops and livestock. When the farmer opens the activity, he will be led through two menus with possibilities. When the right crop or livestock is selected, a list with diseases will be shown containing identification possibilites for a particular diseases. When the farmer notices that one description of the disease is very similar to what is happening to his crops or livestock, he clicks on the disease. When the choice is made another window pops up showing the information the farmer needs to manage and prevent the disease.

Right now it is only possible to access the database and read the information inside the database. What would improve the activity is a way where farmers can access the database and not only read, but also change and add information from the database. This way the information and thus the quality of the activity could be improved without any help from the outside.

The activity can be found on the following page (containing all the code): https://github.com/WorldWideSemanticWeb/farming-activity
