Extending a smart wheelchair navigation by stress sensors

A Comprehensive Review of Smart Wheelchairs: Past, Present, and Future

“…Faria et al 2014 [107] argue that despite many distinct SW projects around the world, the adaptation of their user interface to the patient is an often neglected research topic. They recommend developing new concepts using multimodal [33] Maryland, USA Lehigh University [34] Pennsylvania, USA University of Pittsburgh [35] Pennsylvania, USA Imperial College [36], [37] London, UK Doshisha University [38] Kyoto, Japan University of Bremen [39] Bremen, Germany University of Paris 8 [40] Paris, France Chuo University [41] Tokyo, Japan Toyohashi U.of Technology [42] Tokyo, Japan McGill University [11] Montreal, Canada University of BC [43], [44] Vancouver, Canada University of Aveiro [45] Portugal Universidad Carlos III [46] Madrid, Spain KU Leuven [47] Heverlee, Belgium University of Canterbury [48] Christchurch, NZ U. of Apl.

“…State-of-the-art BCI can even be used to monitor the user's emotional state [45], [57], such that when the user is frustrated the control unit will stop the wheelchair and wait for a new command from the user. In the other case, the control unit will continue executing the previously selected command.…”

Hybrid Solar-RF Energy Harvesting Systems for Electric Operated Wheelchairs

“…Basically, the main components of an EW are: (i) a chassis, which can be foldable and can have different abilities, such as stair-climbing or standing positions, (ii) a controller, which is the interface between human and machine, (iii) a seating system with footrests, lateral supports and backrests, which typically include cushions that use foam, gel, or air to prevent pressure sores, and (iv) a battery unit used to provide energy to the navigation and locomotion system [8]. Although several studies have been conducted to propose innovative solutions to improve ergonomics of chassis and facility of controlling and operating system, addressing different users needs [9][10][11][12][13][14][15][16][17][18], the autonomy of EW's users results still strongly dependent on battery lifetime. Indeed, depending on the operating environment and the weight of users, a frequent recharging process for EW's battery may be necessary [19,20], limiting the travelling distance especially into outdoor environments.…”
