Glare is subjective and can either cause disability or discomfort in eyes. Thus glare during driving especially at night is a serious concern and must be addressed. No commercial product exists to counter the glare, though there had been some academic progress in realizing a solution. The paper presents two promising technologies that help in reducing the oncoming vehicle glare. The system comprises of a vision based identification of glare source. A pixelated transparent film/glass with dynamically controllable transmittance is placed between the driver and source. By changing the transparency locally, glare is avoided without affecting the overall visibility. The paper details on lab results and feasibility of two proposed solution i.e. Use of a matrix of electro chromic films such that each element can be individually controlled and use of transparent LCD such that each pixel is controlled for its transparency. The paper concludes on the next level of cross research required from Automotive, Tier 1's and display manufacturers to create the required technology for solution.
