Abstract [en]

This project aims at making a mock-up of a multigrip tool for a robotic assistive device and a camera systemwhich enable frail elderly to live more independently and tokeep track of their food intake. The robot will be developedthrough user centred design with analyses of real use cases inJapan and Sweden. Thanks to the collaborating researcherswith a strong applied research approach as well as thecompanies with a strong experience in engineering solutionsin both the Japanese and Swedish teams, the functionalities ofBestic, an assistive eating device, could be enhanced forcommercial use, and distributed to municipalities and to thegeneral public

Abstract [en]

The meal is fundamental in terms of nutrition but also from a social perspective. To be able to eat independently is described as important for the meal experience.  

The development of a robotic eating aid called Bestic and the evolvement of a list of usability criteria for such an aid are described in this thesis. The work has been ongoing for 16 years. Bestic has been developed through user centred design, an iterative process with reoccurring evaluations and development. The design principle “it is not supposed just to work, but to be worth using” has guided the work. The feedback provided by the users throughout this process has had a great impact on the strategic choices of which features to prioritize during further development and what to keep as it is and has contributed to the list of usability requirements for robotic eating aids.  

The context in which the robotic eating aid is used is of importance for the usability requirements. To further understand the environment that the robotic eating aid is used in, studies about the meal situation for older people in both Scandinavian/Swedish and Japanese contexts were conducted. The secondary users (care professionals or next of kin) were also taken into consideration when deriving the usability requirements and while performing the evaluations of the robotic eating aid.

The most important research outcome from this work is a list of usability requirements for robotic eating aids. The requirements are divided into functional requirements and social requirements. The functional requirements for robotic eating aids include:

·      how well they work to eat with

·      how they are controlled

·      safety aspects

·      portability

·      possibility to adapt to different users.

 

The social requirements for robotic eating aids include:

·      how to fit into the meal situation

·      not to disturb the conversation

·      the needs from secondary users.     

Abstract [sv]

Måltiden är fundamental för de allra flesta, för att få i sig näring men även som en social aktivitet. Att kunna äta självständigt beskrivs som viktigt för upplevelsen av måltiden.

I denna avhandling beskrivs utvecklingen av ett robotiserat äthjälpmedel som heter Bestic och hur en lista med användbarhetskriterier för robotiserade äthjälpmedel har växt fram. Arbetet har pågått i 16 år. Bestic är utvecklad genom användarcentrerad design, en iterativ process med återkommande utvärderingar och utvecklingssteg. Designprincipen ”den skall inte bara gå att använda, utan vara värd att använda” har lett arbetet. Återkopplingen från användarna genom hela processen har haft stor inverkan på strategiska val för vilka funktioner som skall prioriteras för fortsatt utveckling och vad som skall behållas som det är. Återkopplingen har även utgjort ett underlag till listan med användbarhetskriterier för robotiserade äthjälpmedel.

Miljön som äthjälpmedel används i påverkar också användbarhetskriterierna. För att förstå denna miljö genomfördes studier om måltidssituationen för äldre personer i både en skandinavisk/svensk och japansk kontext. Även sekundära användare (vårdpersonal eller anhöriga) togs i beaktan vid framtagandet av användbarhetskriterierna.

Det viktigaste forskningsbidraget från detta arbete är en lista av användbarhetskriterier för robotiserade äthjälpmedel. Kriterierna är uppdelade på funktionella och sociala kriterier. 

De funktionella användbarhetskriterierna för robotiserade äthjälpmedel inkluderar:

·      hur bra de fungerar att äta med

·      hur de styrs

·      säkerhetsaspekter

·      bärbarhet

·      möjlighet att anpassa till olika användare.

 

De sociala användbarhetskriterierna för robotiserade äthjälpmedel inkluderar:

·      hur den passar in i måltidssituationen

·      att inte störa konversationen

·      behoven från de sekundära användarna.
