Nokia near-eye display gaze interaction update

The Nokia near-eye gaze interaction platform that I tried in Finland last year has been further improved. The cap used to support the weight has been replaced with a sturdy frame and the overall prototype seems lighter and also incorporates headphones. The new gaze based navigation interface support photo browsing based on the Image Space application, allowing location based accesses to user generated content. See the concept video at the bottom for their futuristic concept. Nokia research website. The prototype will be displayed at the International Symposium on Mixed and Augmented Reality conference in Orlando, October 19-22.

DoCoMo EOG update

While eye movement detection using EOG is nothing new the latest demonstration by Japanese NTT DoCoMo illustrates recent developments in the field. The innovation here is the form factor which is quite impressive. Typically EOG is detected using electrodes placed around the eyes as in Andreas Bullings prototype demonstrated at CHI 09 in Boston. Now it can be done using tiny sensors inside the ear. Just compare it to the prototype demonstrated last year!
