The motivation of this article is to analyze and define the barriers and opportunities in senior people’s adaptation to the Internet-based services in Turkey. Digitalization has emerged in developed countries where people’s lifestyle was molded by it, then the technology diffused to the developing countries including Turkey. With this emergence, internet-based applications have entered into people’s daily life activities such as shopping and using banking services. However, Turkey can be seen as a late-adopter of these digital technologies, yet Turkish companies have been fairly quick in adaptation and improving internet-based services to local needs. Today, many young and middle-aged users in Turkey are using above-mentioned services, and they take internet-based applications for granted in their daily life activities. On the other hand, senior people could not catch up with the diffusion of these kinds of internet-based services. There seem to be barriers to the adaptation of elderly people to the digitalized world and it seems to prevent usage of internet-based applications which makes accomplishing those tasks easier. A design researcher’s perspective can point out opportunity areas and provide innovative solutions to overcome barriers to adaptation. In this study, our approach is to conduct ethnographic interviews with senior people in Turkey in order to understand how they use internet-based services and how digitalization in this aspect is affecting their life. The second part of this study is to understand internet-based service providers’ perspective. By conducting interviews at service provider companies, we aim to understand their approach regarding the inclusion of senior users. As a result, service providers and end users will be examined simultaneously, therefore deeper analysis and conclusions will be obtained. To our knowledge, there is no research study investigating adaptation to internet-based services of seniors in Turkey from a design research perspective. As a conclusion, this study investigates the barriers in the adaptation of internet-based services by senior people in Turkey, and the study aims to find opportunities where design can help with the integration of the digital world and senior people.

Environmental force estimation for a robotic hand : compliant contact detection
(IEEE, 2015) Kaya, Osman; Yıldırım, Mehmet Can; Kuzuluk, Nisan; Çiçek, Emre; Bebek, Özkan; Öztop, Erhan; Uğurlu, Regaip Barkan; Computer Science; Mechanical Engineering; BEBEK, Özkan; ÖZTOP, Erhan; UĞURLU, Regaip Barkan; Kaya, Osman; Yıldırım, Mehmet Can; Kuzuluk, Nisan; Çiçek, Emre
This paper presents a model based compensation method to enable environmental force estimation for a robotic hand with no tactile or force sensors. To this end, we utilize multi-joint robot dynamics and disturbance observer based friction identification methods based to account for forces that arise due to Coriolis, gravity, stiction and viscous friction. With the effective compensation of these forces, disturbance observer units, implemented for each joint, allow us to estimate environmental interaction forces. To validate the effectiveness of the force estimation with our method, experiments were conducted on an anthropomorphic robot with no haptic sensing capability. The results of these experiments showed that the force estimation was in good agreement with the actual sensor measurements. To further elaborate the effectiveness of the method, compliant contact detection task was implemented on the robot. The result of this experiment indicated that environmental force estimation performance was enough to facilitate the task, and as such our method may eliminate the need for expensive force sensors at the finger tips or the joints for dexterous manipulation.
