Cerebral Palsy (CP) is the most common cause of motor deficiency in young children, it occurs in only 2 to 3 per 1000 live births.” [1] To help to improve the motor skills of children, ranging from 2,5-8 years old with hemi paresis due to Cerebral Paresis, the Sint Maartenskliniek in Nijmegen has started a therapy group called “de Piratengroep”. During the therapy session the TagTile of SeriousToys could be used to help and motivate the children doing repetitive tasks. This TagTile is a tangible objects table which uses tangible objects for input and has both audible and visible feedback. The table is currently being launched commercially for use in primary school to train cognitive skills. Current games for improving motor skills on their earlier version of the table are not yet good enough in triggering the right movements in a repetitive way, among others because of compensating body movements and software stability issues.
During this graduation project there should be an effective design of a game and accompanying physical objects for this tangible object interface table. The game has to help these children to train their motor skills in a user-initiated way. This will be reached by analyses of children with unilateral spastic cerebral paresis [1], looking into the technical possibilities and limitations of the TagTile, exploration of how to design with children which will be followed by a customised iterative participatory design approach resulting in a final evaluated version of the game for the TagTile. During these activities new insights in designing with children will be generated and yet to be decided case specific research questions will have to be indicated and answered (e.g. questions about competition/collaboration, audible feedback issues, adaptive/adaptable game differentiation, effect of empathy in evaluation, rewarding and motivating in general).

Het Klant Contact Systeem geeft de mogelijkheid aan gemeentes om via de verschillende kanalen de burger te voorzien van antwoord of (te helpen bij) aanvragen. Het doel van de opdracht bij de Exxellence Group is dat dit Klant Contact Systeem voor gemeentes aan een kritische blik wordt onderworpen om de gebruikerservaring verder te verbeteren. Daarbij zal ook worden gekeken naar mogelijkheden van het inzetten van een PDA voor buitenmedewerkers bij de gemeente. Te denken valt aan medewerkers van straat-, riolerings- en groenonderhoud en verscheidende toezichthouders die met behulp van de PDA gemakkelijk zaken kunnen invoeren en afhandelen.
Deze opdracht zal bestaan uit het doen van een evaluatie van het huidige systeem doormiddel van een heuristische evaluatie, interviews en observaties. Daarnaast zal doormiddel van het in kaart brengen van huidige technologie en toepassingen een beeld gevormd worden van de mogelijkheden voor gebruik van een PDA. Hierbij spelen zowel de huidige ontwikkelingen binnen de overheid als de stand van de technologie en de toekomst hiervan een belangrijke rol. Met behulp van deze analyse aangevuld met guidelines voor het ontwikkelen van software/websites voor PDAs zal een proof of concept gemaakt worden.

In the last decade social network sites have been rapidly growing. Besides messaging, playing games and sharing information the sharing of photos has become an important part of these sites. Each month on Facebook alone 2.5 billion photos are uploaded (blog.facebook.com 2010). The amount of information willingly shared by people on their profile is astonishing. Another important trend is the usage of internet using smartphones with dedicated applications for social network sites. This combined with improving feature and face recognition algorithms which are publicly available (Everingham et al 2006, OpenCV) could lead to interesting new systems.
Several papers can be found on the use of context for face recognition for tagging but most deal with on-photo context or friendship networks (Stone et al 2008 2010; Mavridis et al 2009 2010). We expect that overall person recognition using social network communities could significantly improve when people would use both personal information, such as home town or age, and a photo.
There are many possible usage scenarios. A positive and important one is being able to retrieve the name and get in contact with someone you only spoke briefly and have a picture of. This scenario will be used as the basis for the prototype.
In this research we will try to show that it is indeed possible for users to identify a person with only a photo and some personal information from a ranking out of a set of hundreds of persons. This will also emphasize the usage of context from outside the photo itself. Although the realtime usage with a smartphone is very attractive we will first start with a desktop application. A prototype consisting of some text fields for input of personal information followed by a simple user interface showing the most similar persons will be used for a small evaluation. In this evaluation the effectiveness of identifying a person given some context will be compared to identifying a person only using context of the photo. To speed up development and to have a suitable test set, a part of the corpus based on a Dutch online social network for dance party visitors (Poppe 2011) will be used. |
