So far, pedestrians must look on the phone’s display or put on speech, if they want to navigate with their Smartphone. German researchers are developing a system in which the direction of instructions as a kind of remote control directly in the legs go.
German researchers are working on a navigation aid, where the direction of notes directly as electrical impulses in the leg muscles are supplied. Users could download the Navi app to your smartphone, with which you don’t have to constantly look at the display.
For the trend-setting current pulses, electrodes are attached to the thigh of walkers. They then stimulate the running from the basin up to the Shin Schneidermuskel (Musculus sartorius), which bends the knee and hip, as well as allows thigh turns. The pulses occur while walking if the respective leg in the air is, and cause a slight external rotation. This will affect the direction of rotation. This impulse of pedestrians could counter but also aware and resist, the researchers emphasize. The pedestrian stops, nothing was happening because the impulses for the rotation of the leg are too weak.
Via Bluetooth can be for example with a Smartphone connected the electrodes of’s from the walkers then effectively be controlled remotely. First tests with a prototype at the 18 subjects by mobile phone were guided through a busy Park in Hanover, had been positive. Most of the participants with the technology be coped after a short acclimatization. It feels like when a tempo slider in the car in which the driver at any time could take control, the study cited one of the subjects.
Application fields for their muscular navigation researchers about can imagine wearables to lure firefighters on missions by unknown buildings. Also could thus run tourist attractions or players in team sports will receive the necessary impulses from the coach. The scientists want to present their findings at a conference this week to the human-computer interaction in Seoul.
