Ubiquitous Help System–Selection (UHS–Selection)

Ubiquitous Help System-Selection (UHS-Selection) is a context-aware social computing prototype system that assists users in two discrete ways. In one way, it helps the user to select relevant contextual information that is necessary to exchange in a conversation with persons from distant places. In any social conversation in a collocated environment, we share a lot of contextual information both implicitly and explicitly. However, when we communicate with persons from distant places, it is difficult to convey the contextual information that we share implicitly while we perform the same conversation in a face-to-face communication. Furthermore, there is a lot of contextual information, and it is difficult to identify which contextual information is important and necessary to convey. The UHS-Selection system captures and prioritizes a dynamic list of contextual information to assist the user in the selection process.

When a user is looking for a reliable help from a trusted social peer, additionally, the UHS-Selection system helps the user to identify a group of potential help providers within his social network. Selecting a group of potential help providers while on the go is a cumbersome task. Depending on the contextual information, the system presents a list of potential help providers to the users.

Ubiquitous Help System for Persons with Dementia (UHSd)

Ubiquitous Help System for Persons with Dementia (UHSd) is a software prototype developed together with Joël Vogt, from University of Fribourg (Switzerland). It fits in the domain of assistive living for people with dementia. When dementia syndrome progresses, persons with dementia increasingly need spatio-temporal, social and navigational support. The UHSd system strengthens the involvement of caregivers through the patient’s social network. Typically running on the Android device, UHSd provides targeted help by providing it only when it is necessary; without potentially patronizing its user! A raw video could be found here.

Ubiquitous Help System (UHS)

Ubiquitous Help System (UHS) is a software prototype that allows user to find context aware interactive information help from potential users present in the vicinity. Typically it runs on (mobile) client devices and can communicate with other clients within the vicinity. It utilizes the power of Social Network (SN) to find friend of a friend (FOAF). It also takes into account the users’ profile and preferences. A distributed architecture made it possible to scale up the system. The system utilizes RDF query language SPARQL for searching the distributed databases.

Marine Stabilized Satellite Communication System (SatMax)

I (together with my colleagues in SatPoint AB, Stockholm, Sweden) have developped an interactive system for marine stabilized stellite communication system under the SatMax project. We have utilized the User Centered Design (UCD) approach. The system runs on PC-101 harware running on customized Linux. We have utilized: Python, PHP, Java, HTML, CSS etc. For more detail please visit my *old* website in KTH, here.
