Usable Persona Interface: Persona-Bookmark

We present a design that assigns persona information and uses it to selects one identity from several user identities in user resources such as bookmarks. As a proof of concept, we implemented a persona-bookmark system. In this system, a user can assign his persona information to his bookmarks so that the system automates login processes using the persona information. Thus, the user can log int...

Conjoint PERSONA - SOPRANO Workshop

Being both EU-IST integrated projects in the field of AAL, PERSONA and SOPRANO organized a conjoint workshop on the occasion of the AmI-07 conference in order for the researchers of the projects to exchange insights of the approaches to the key field challenges, the achievements so far in each of the projects, and possible synergies in the future. Here, we summarize the exchanged info and the w...

Enveloping Manifolds

We study the problem of embedding compact subsets of Rn into C1 submanifolds of minimal dimension. In [4], we define a generalized tangent space TxA suitable for a general compact subset A of Rn and we prove that A may be locally embedded into a C1 manifold of dimension dim(TxA). This result leads naturally to the global conjecture that for a compact subset A of Rn, there exists a C1 manifold M...

Persona: A Contextualized and Personalized Web Search

From Persona to Techsona

In this paper we introduce the notion of techsona, as a possible counterpart design instrument to personas. We use a case study to illustrate a design process where techsonas help pinpoint technological ideas and alternatives and analyze these systematically. While a persona captures “imagine a user...”, a scenario “imagine a situation...” the techsona gives the missing piece of “imagine a tech...
