“…This suggest that the selection and use of appropriate material that will enhance comfort should attract adequate attention. This is supported by the findings of Lebrasseur et al (2019) that the ability and possibility of performing daily activities with ease will reduce stress and possibly elongate life span especially if achieved within the living spaces. Folorunso and Ahmad (2013) observed that several finishing materials are in use in Nigeria.…”

PurposeWood is one of the materials that is used for building construction either as structural member or as finishes from ages past to contemporary generation. It is composed of elongated, hollow spindle shaped cells that are arranged parallel to each other along the trunk of a tree. The resistance to water, chemicals, strength properties, appearance and decay rate is dictated by the fibrous cells. The purpose of this paper was to examine the application and use of wooden floor finish (an extract from wood) in residential buildings in Lagos, Nigeria, with a view to determine its effectiveness.Design/methodology/approachThe study adopted a dual stage survey approach before the administration of questionnaire on 100 respondents that were selected through purposive sampling after the initial inquiry on the use of the material from 384 randomly selected samples from the entire population.FindingsThe study shows that the material is applied in all interior spaces except bathrooms and toilets. Minimal adoption is also seen in the kitchen area. Users indicate that wooden floor finish requires little maintenance, has low impact on users' health, considered safe-minimal occurrence of home accidents is recorded, has moderate thermal insulation and affordable.Practical implicationsThe usage has impact on the environment due to continuous lumbering activities and lack of adequate plan for reforestation. This suggests that its sustainability depends on afforestation programmes. Its poor performance in sound insulation, water and fire resistance requires further attention. The maintenance is relatively easy and affordable.Originality/valueThe author made a new foray into investigating the performance of wooden floor finish due to its resurgence in the area bearing in mind the unseasoned condition of wood in circulation in the area. Previous adoptions were done by a less aggressive generation of well-trained artisans. Best places for its usage within the interior spaces are identified.

Impacts of a Robotic Arm on People with Upper-Limb Disabilities Due to Neuromuscular Disorder

Introduction:Research is still limited on the impacts of robotic arms in improving independent living and social participation of individuals with upper-limb disabilities, and several knowledge gaps remain. This study aims to investigate the impacts of the JACO robotic arm on individuals with upper-limb impairments due to a neuromuscular disease. Methods: For this prospective study, participants used the robotic arm in their daily life for a 2-month period. The effectiveness of the robotic arm was objectively observed during activities performed in a controlled environment. The perception of the users and of their main family caregivers was also documented. Finally, the nature and importance of activities carried out with the robotic arm in a community-living environment were explored. Results: Participants' abilities with the JACO robotic arm improved continuously during the trial duration. Participants actively took part in more life habits, perceived fewer difficulties, and were more satisfied with their social participation. Despite these findings, very few life habits could be performed completely independently, limiting the impacts on global caregivers' burden. Conclusions: Even if participants encountered some difficulties, this study demonstrates short-term benefits of the robotic arm for individuals with upper-limb impairments due to a neuromuscular disorder. Future studies should mainly focus on the psychosocial, economic, and occupational long-term impacts of the robotic arm. The development of services to assist the integration of such devices in people's lives could optimize their impacts. Clinical Relevance: The results of this study contribute to the body of knowledge of clinicians for the prescription of a robotic arm. (

“…In any case, a common way to deal with the interface's lower dimensionality is often to arrange the AT's modes in sub-control groups. As shown in Figure 1, with this approach, accessing a mode can require a series of actions to browse through the nested groups [1,15,16]. Thus, a strategy needs to be implemented within the interface to either reduce the total number of modes, facilitate switching between them, or somehow artificially augment the dimensionality of the interface itself.…”

“…At each level, the modes are proposed to the user, one-by-one, and the user activates the switch when the mode they want is proposed. Although this strategy is quite robust (due to its simplicity) and, thus, commonly found in practice [19], it is time consuming and does not lead to a satisfactory user experience [15].…”

Assistive technologies (ATs) often have a high-dimensionality of possible movements (e.g., assistive robot with several degrees of freedom or a computer), but the users have to control them with low-dimensionality sensors and interfaces (e.g., switches). This paper presents the development of an open-source interface based on a sequence-matching algorithm for the control of ATs. Sequence matching allows the user to input several different commands with low-dimensionality sensors by not only recognizing their output, but also their sequential pattern through time, similarly to Morse code. In this paper, the algorithm is applied to the recognition of hand gestures, inputted using an inertial measurement unit worn by the user. An SVM-based algorithm, that is aimed to be robust, with small training sets (e.g., five examples per class) is developed to recognize gestures in real-time. Finally, the interface is applied to control a computer’s mouse and keyboard. The interface was compared against (and combined with) the head movement-based AssystMouse software. The hand gesture interface showed encouraging results for this application but could also be used with other body parts (e.g., head and feet) and could control various ATs (e.g., assistive robotic arm and prosthesis).
