Abstract:Vizualno-kinestetična naprava za slepe in slabovidne je dolgoletni projekt, ki smo ga pričeli z namenom, da slepim in slabovidnim pomagamo pri vsakodnevni orientaciji in mobilnosti v prostoru. Naprava je sestavljena iz dveh delov. Prvi predstavlja očala, ki jih uporabnik nosi na glavi. Ta poskrbijo za določitev usmerjenosti pogleda ter zaznavo ovir v vidnem kotu bližnje okolice. Drugi del naprave predstavlja pas, ki ga uporabnik nosi na abdominalnem predelu in je z očali povezan preko brezžične komunikacije. Ta uporabniku zaznane ovire interpretira preko vibracijskih vzorcev. Med izvedenimi testiranji, ki smo jih opravili s testnimi subjekti na za to namensko zasnovanih poligonih, smo ugotovili, da nimamo zadostnega pregleda nad meritvami in splošnim delovanjem naprave. Prav tako smo se morali zanašati le na opisane občutke uporabnikov, ki pa so znali biti subjektivni. V ta namen smo implementirali zajem podatkov, shranjevanje le-teh v datoteko ter njihovo vizualizacijo v simulacijskem okolju Unity. To nam je omogočilo boljši pregled nad pridobljenimi meritvami in lažjo zaznavo napak med delovanjem naprave. Naknadne meritve z dodano vizualizacijo so nam razkrile prej še ne odkrite napake v zaznavanju okolja. To nam je omogočilo boljši vpogled v delovanje in razumevanje naše naprave.

Title:Calculation and visualization of the orientation of the visual-kinesthetic device for blind and visually impaired using inertial sensor and magnetometer
Abstract:Visual-kinesthetics device meant to aid the blind and visually impaired is a long-term project we have started to aid the recipients in every-day orientation and spatial mobility. The device consists of two parts. The first part are the glasses worn on the users’ head. These allow for the setting of the field of vision and recognition of any obstacles in the immediate surroundings. The second part of the device is a belt worn on an abdominal part. This belt is connected to the glasses through wireless communications. The belt interprets the obstacles recognised by the glasses through vibration patterns. During the testing of the device in the specially designed testing grounds we have discovered that we do not have sufficient overview of the measurements and general operations of the device. We were forced to rely on the described feelings of the users which tended to be subjective in nature. We have implemented data capture, data saving and their visualisation in the Unity simulation environment. This allowed us to have a better oversight regarding the collected measurements and allowed for far simpler detection of malfunctions. Supplementary measurements have shown several not yet discovered flaws in the environment detection process. This offered us a better understanding of the workings of our device.
